Additional Safety for CNC Mills/Lathes

You can be seriously injured or killed by getting clothing, jewelry, or long hair entangled with rotating cutter/spindle. You can be severely cut or have fingers amputated from contact with rotating cutters. You can be blinded or struck by broken cutting tools, metal chips, workpieces, or adjustment tools thrown from the rotating spindle with great force. To reduce your risk of serious injury when operating this machine, completely heed and understand the following:

UNDERSTAND ALL CONTROLS. Make sure

you understand the function and proper use of all controls before starting. This will help you avoid making mistakes that result in serious injury.

AVOIDING ENTANGLEMENT. DO NOT wear loose clothing, gloves, or jewelry, and tie back long hair. Keep all guards in place and secure. Always allow spindle to stop on its own. DO NOT stop spindle using your hand or any other object.

EYE INJURIES. Operator and bystanders MUST wear ANSI-approved safety glasses to help protect eyes from thrown metal shards and chips.

USE CORRECT SPINDLE SPEED. Follow recommended speeds and feeds for each size and type of cutting tool. This helps avoid tool breakage during operation and ensures best cutting results.

INSPECT CUTTING TOOL. Inspect cutting tools for sharpness, chips, or cracks before each use. Replace dull, chipped, or cracked cutting tools immediately.

UNATTENDED MACHINE. Operator MUST be present to immediately stop machine in case of malfunction to prevent injury to bystanders and machine damage.

POWER DISRUPTION. In event of power outage during operation, turn spindle switch OFF to avoid a possible sudden startup once power is restored.

SECURE WORKPIECE TO TABLE. Clamp workpiece to table or secure in a vise mounted to table, so workpiece cannot unexpectedly shift or spin during operation. NEVER hold workpiece by hand during operation.

DISCONNECT POWER FIRST. To reduce risk of electrocution or injury from unexpected startup, make sure mill/drill is turned OFF, disconnected from power, and all moving parts have come to a complete stop before changing cutting tools or starting any inspection, adjustment, or maintenance procedure.

CLEAN MACHINE SAFELY. Metal chips or shavings can be razor sharp. DO NOT clear chips by hand or compressed air that can force chips farther into machine—use a brush or vacuum instead. Never clear chips while spindle is turning.

PROPERLY MAINTAIN MACHINE. Keep machine in proper working condition to help ensure that it functions safely and all guards and other components work as intended. Perform routine inspections and all necessary maintenance. Never operate machine with damaged or worn parts that can break or result in unexpected movement during operation.

SAFE OPERATING LOCATION. DO NOT place machine where it can be exposed to rain or moisture. Exposure to water creates a shock hazard and will reduce life of machine.

POWER SUPPLY

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes and standards.

or equipment damage may occur if machine is not properly grounded and connected to power

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the specified circuit requirements.

This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements:

Note: Circuit requirements in this manual apply to a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult an electrician or qualified service personnel to ensure circuit is properly sized for safe operation.

For your own safety and protection of

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power supply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time.

regarding the total connected power of the milling machine.

 Firmly connect the machine.

CAUTION!

Install the connection cable of the machine in such a way that people will not stumble over it.

Please verify if the type of current, voltage and protection fuse correspond to the values specified. A protective earth ground wire connection must be available.

 Main Fuse 16A.

Due to the design, the leakage current is greater than 3••5 mA. We ask for due attention while executing machine tests within the framework of industrial safety guidelines.

ATTENTION!

When delivered the machine is equipped with a plug for electrical connection. It only serves for acceptance and test purposes. In order to operate the machine it is necessary to remove this plug and to connect the machine directly with a power supply.

Firmly connect the CNC machine to the terminal box. It is not allowed to connect the machine using a standard 16A CEE plug, since the stray current of the frequency converter is exceeding the admissible value of 3.5mA.

ATTENTION!

Depending on the quality of the network, there is a risk of machine malfunctions under extreme conditions. If necessary and in order to exclude retroactive effects on the internal power supply system, the operator should install a line filter on the machine. Therefore, at workplaces with lots of powerful consumers, it might also be necessary to use a system for network compensation. Please consult your electricity supplier regarding this.

ATTENTION!

Frequency converters (drive regulators) might trigger the Fl circuit breaker of your electrical supply. In order to avoid malfunction, an Fl circuit breaker switch sensitive to pulse current or to universal current may be required.

ATTENTION!

Ensure that all 3 phases (L1, L2, L3) and the ground wire are connected correctly.

The neutral conductor (N) of its power supply is not connected.

3.5.5 Current in the Protective Earth Ground Wire

Since a direct current may be caused by the frequency converter in the protective earthing conductor, if an upstream residual current device (ELCB / RCD) is required in the network, the following guidelines must be followed:

There are three common types of FI (ELCB / RCD):

 AC - to detect AC fault currents  A - to detect AC fault currents and pulsating DC fault currents (provided the DC current

reaches zero at least once every half cycle).

 B - to detect AC fault currents, pulsating DC fault currents and smooth DC residual currents.

Type AC should never be used in converters.

Type A can only be used for single-phase converters.

Type B must be used for 3-phase converters.

Model G0877 (Mfd. Since 02/19)

When using an external EMC filter, to avoid false error shutdowns, a time delay of at least 50 ms is required. The leakage current can exceed the threshold trigger value for an error shutdown if the phases are not switched on at the same time.

Line systems

The CNC milling machine is designed for TN and TT line systems with a grounded neutral point.

Prohibited operation

Operation on TN line systems with grounded external conductors is prohibited.

Operation on TT line systems without grounded neutral points is prohibited.

Operation on IT line systems is not permitted. In an IT line system, all of the conductors are insulated with respect to the PE protective conductor – or connected to the PE protective conductor through an impedance. Operation on an IT line system is not permitted.

Permissible line supplies

Operation on TN and TT line systems

TN line system

The TN line system in accordance with IEC 60364-1 (2005) transmits the PE conductor to the installation via a conductor. Generally, in a TN line system the neutral point is grounded There are versions of a TN line supply with a grounded line the conductor, e.g. with grounded L1.

A TN line system can transfer the neutral conductor N and the PE protective conductor either separately or combined.

TT system

In a TT line system, the transformer grounding and the installation grounding are independent of one another. There are TT line supplies where the neutral conductor N is either transferred – or not.

4 General information about CNC

4.1 Compensation of geometry

It is necessary to be able to measure any currently actual position of the CNC-controlled axis in order to perform tool moves on workpieces.The measured value is related to a machine fixed zero position and is compared to the target position which is predefined by the programs.

Required knowledge:

 coordinate systems of the machine and workpiece  reference points of the machine, tool and workpiece  type of distance measurement  options of dimensioning and dimension compensation

Basics:

For chip removal relative moves between the tool and the workpiece are required. For programming all moves are related to the resting workpiece.

4.2 Coordinate systems on CNC-machine tools

Types of coordinate systems

Coordinate systems allow the exact description of all points on a working plane, respectively in an area.

Generally they are divided into

 Cartesian coordinate system and  the polar coordinate system

4.2.1 Cartesian coordinate system

A Cartesian coordinate system also called a rectangular coordinate system possesses two coordinate axes (two-dimensional Cartesian coordinate system) or also three coordinate axes (three-dimensional Cartesian coordinate system) which are perpendicular to one another in order to exactly describe the points.

On a two-dimensional Cartesian coordinate system, e.g. on the X, Y-coordinate system, each point is clearly defined on the plane by indicating the coordinates (X,Y).

The distance from the Y-axis is called the X-coordinate and the distance from the X-axis is called Y-coordinate. Those coordinates may possess positive or negative algebraic signs.

The three-dimensional Cartesian coordinate system is required to display and determine the position of special workpieces, e.g. milling parts.

In order to clearly describe a point in the space, three coordinates are required which are named according to the corresponding axes X-, Y- or Z-coordinates.

Such three-dimensional coordinate systems with positive and negative areas on the coordinate axis allow the exact description of any locations, e.g. in the working area of a milling machine, independent from where the zero point of the workpiece is set.

Model G0877 (Mfd. Since 02/19)

-37-

4.2.2 Polar coordinate system

In the Cartesian coordinate system a point is described by e.g. its X- and Y-coordinate. For rotation-symmetric outlines, e.g. circular drilling images the required coordinates can only be calculated with considerable effort.

In the polar coordinate system a point is described by means of its distance (radius r) to the coordinate origin and its angle (a) to the defined axis. The angle (a) is related to the X-axis of the X, Y coordinate system. In opposite direction it is negative.

4.2.3 Machine coordinate system

The machine coordinate system of the CNC machine tool is determined by the manufacturer. It cannot be changed. The position of the origin point for the machine coordinate system, also called machine zero point cannot be changed.

Any tool moves are generally defined in a standardized, right-handed coordinate system.

Turns from +X to +Y are created in +Z direction, which result in a right-handed screw.

Z-axis:

According to the standard it is equal to the working spindle or continues in positive direction starting from the workpiece.For milling it continues directed to the spindle perpendicular on the clamping surface (only for perpendicular milling machines) for several spindles one main spindle is determined.

X-axis:

Continues horizontally and parallel to the clamping surface

for vertical Z-axis: +X to the right

for horizontal Z-axis: +X to the left .

Img.4-1: Vertical Z-axis

Y-axis:

At a right angle to the Z- and X- axis in a way that a right-handed coordinate system is resulting

4.2.4 Workpiece coordinate system

The workpiece coordinate system is determined by the programmer. It can be changed. The location of the origin point for this workpiece coordinate system, also called workpiece origin point is generally user-defined.

4.2.5 Rotary axes and secondary axes

NC machines with rotary table or swivel head

Rotary axis: A B C

Positive turn around X, Y, Z (right- hand-rule)

NC machines with several feed axes

Secondary axis: U V W

Parallel to the X-,Y-,Z-axis

4.3 NC mathematics

4.3.1 Basics of the coordinate calculation

For the CNC programming the corresponding points of the outline which is to be machined need to be entered. In most cases if the drawing is suitable for NC purposes, it is possible to directly transfer these coordinate points from the drawing. In some cases it may be necessary to calculate the coordinates.

In the frame of the automation those coordinates are calculated by an NC programming system at external working places and the data are directly transferred to the machine. Therefore, in most cases the NC programming is directly performed on the product (3D pattern) in the construction or in the process engineering department.

For the computer-aided programming the switch and path information are entered over the keyboard in the dialogue using the menu technique.

4.3.2 Parameters of a triangle

In order to calculate the missing coordinates the relations valid for a triangle are very useful. There are several options to describe a triangle. Some of the following parameters e.g. corners, angles or sides are being used.

4.3.3 Angle on a triangle

The angles on a triangle determine the type of triangle. Depending on the size of the individual angles we distinguish between acute-angle, obtuse angle or rectangular triangles.

On triangles the following relation is applied:

the sum of the angles a, b and g in a triangle always amounts to 180°.

a + b + g = 180°

If two angles are known it is possible to determine the third unknown angle by means of this formula.

Rectangular triangle

The rectangular triangle has a special meaning in the analytic geometry as the sides of such a triangle are having a definite mathematic relation to one another.

On a rectangular triangle the single sides are specially named.

 The longest side is located opposite to the right angle and is named hypotenuse.  The two sides of the triangle which are forming the right angle are named cathetus.  The side opposite the angle a is named opposite leg.  The side adjacent to the angle a is named adjacent leg.

On a rectangular triangle the right angle is described by an quarter circle and a point in the angle.

In a rectangular triangle it applies:

In a rectangular triangle you can calculate the missing leg if the other leg lengths are known. To do so, use the Pythagorean theorem.

Model G0877 (Mfd. Since 02/19)

-39-

The Greek Pythagoras (from about 580 to 496 B.C.) had been the first person to prove the following mathematic relation which had later on been named the Pythagorean the-

orem.

The sum of the cathetus square is equal to the hypotenuse square and expressed as a equation:

a² + b² = c²

4.4 Trigonometric functions

The trigonometric functions describe the relations between the angles and the sides of a rectangular triangle. With the help of these trigonometric functions it is possible to calculate unknown leg lengths with an unknown angle and a known leg. It is depending on which side and which angle are known in order to choose the appropriate trigonometric function e.g. the sinus function, the cosine function or the tangent function.

For the calculation of unknown legs the corresponding equation needs to be transformed as described in the following example:

Known are: the angle and the length of the adjacent leg

Looking for: the length of the opposite leg

It applies: tan alpha = opposite leg / adjacent leg

The results is:

opposite leg = adjacent leg x tan alpha

6.4 Programming

For further working steps please proceed as described in the operating instructions "Part programming, system, programming and cycles“ for SINUMERIK 808D.

Manual resp. part programming:

For this kind of programming, the programs must be created manually and entered in the control. The direct programming in the DIN-Code is a complex method which requires lots of skills. Nowadays this task is mostly taken over by CAD/CAM systems which directly create an operating program using a graphical user interface.

Automatic programming:

By means of the CAD/CAM program (for instance a 3D-CAD program including downstream co-processor) construction data are transmitted (semi-)automatically to an executable program. For this kind of programming a 3D model is designed using a PC. By means of an operating sequence which is predefined by the user the motion-sequence of the machine are being calculated. These programs are accessing the tool data base which includes all tool parameters (speed, feed, diameter, etc.). Due to this systematic program structure the user is able to create complete programs within shortest time without having any knowledge of the individual program commands and its syntax.

6.9 Central lubrication system

The CNC-machine is equipped with a central lubrication system.

The lubricating system is used to maintain an oil lm on the slideways, the bearings, the ledges and the ball screws and to reduce their wear.

In case of a failure or a fault in the central lubricating system a stick-slip eect may occur. This eect describes the jerky sliding of solids moving opposite one another. For instance: creaking doors and rattling windscreen wipers.

6.10 Data interfaces and current collection

When connecting data interfaces make sure that the data cable runs to the interface of the controlwithin shortest possible distance. The cable routing can be conducte d along the measuring system lines. However the cable in the switch cabinet must never be routed nearby the drive apparatuses of the NC axis or the frequency converter itself. Errors occur during data transfer due to electromagnetic radiation (EMC-problems).

The control is equipped with the following data interfaces. They are located laterally on the control panel of the CNC-maschine:

m RJ45 plug- in connection m USB connection m Connection for power supply

6.11 Selecting the speed

The correct speed is an important factor for m illing. The speed determines the cutting speed by which the cutting edges cut the material. By selecting the correct cutting speed, the service life of the tool is increased and the working result is optimized.

The optimum cutting speed mainly depends on the materi tools (milling cutters) made of hard metal or ceramic insert it is possible to work with higher speeds than with tools made of high-alloy high speed steel (HSS). You will achieve the correct cutting speed by selecting the correct speed.

In order to determine the correct cutting speed for your tool and for the material to be cut you may refer to the following standard values or a table reference book.

al and on the material of the tool. With

The required speed is calculated as follows:

 When drilling a cooling or lubricating agent should be used.  For stainless materials (e.g. VA – or NIRO steel sheets) do not center as the material would

compact and the drill bit will become rapidly blunt.

 The workpieces need to be tensed in flexibly and stably (vice, screw clamp).

INFORMATION

High temperatures are generated at the tip of the tool by the occurring friction heat. The tool should be cooled during the milling process. By cooling with an appropriate coolant lubricant you will achieve a better working result and longer durability of the tool.

INFORMATION

Use a water soluble environmentally compliant emulsion as cooling agent procured from the specialized trade.

Make sure that the cooling agent is properly retrieved. Respect the environment when disposing of any lubricants and coolants. Follow the manufacturer’s disposal instructions.

INFORMATION

The CNC milling machine is lacquered with a one-component paint. Observe this fact when selecting your cooling lubricant.

11.1 Operating material

11.1.1 Machine lubricants

Only use appropriate lubricants which guarantee a safe operation of the machine.

Recommended lubricant class: ISO V668 Recommended lubricant: guideway oil Mobil Vactra (Oil No. 2) 2)

11.1.2 Cooling lubricants

In order to avoid interferences during operation the water-mixed cooling lubricant and the slideway oil or grease need to be compatible.

INFORMATION

The CNC-milling machine is lacquered with a on e-component paint. Observe this fact when selecting your cooling lubricant.

The company Grizzly Industrial, Inc. does not assume any guarantee on subsequent damages due to unsuitable cooling lubricants.

The ashing point of the emulsion must be higher than 140°C.

When using non water-mixable cooling lubricants (oil content > 15%) with ashing point ignitable aerosol air mixtures might develop. There is a potential danger of explosion.

ATTENTION!

Only the correct selection of an appropriate combination of cooling lubricants and slideway oils as well as the proper care and maintenance of the cooling lubricant can ensure that no problems such as stick-slip eects or deposits are resulting.

The selection of cooling lubricants and slideway oils, lubricating oils or greases as well as their care are being determined by the machine operator or operating company.

Therefore, Grizzly Industrial, Inc. cannot be held liable for machine damages which are caused by unsuitable coolants and lubricants as well as by ina and servicing of the coolant. In case of problems with the cooling lubricant and the slideway oil or grease, please contact your supplier for mineral oils.

ATTENTION!

For safe functioning of the CNC-machine the cooling lubricant needs to be checked at least weekly also during down times with regard to its concentration, ph-value,bacteria and fungal decay.

ATTENTION!

Cooling lubricants and oils for the mechanic and pneumatic system of the machine have to be adjusted referring the water added initially, the cooling lubricant emulsion and the machining task.

We would like to ask you to have the following machine-related properties of the cooling lubricant conrmed in writing by the ma nufacturer of the cooling lubricant.

m The products need to comply with the current regulations of the law and of the employers

WARNING!

The polycarbonate windows are part of the safety device on your CNC machine.

Damaged, scratched or even broken polycarbonate windows must be replaced immediately.

A soft cloth should be used to clean the machine safety glass.

We recommend to replace the polycarbonate windows of the door after 60 months of commissioning of the CNC machine.

In the following cases, an immediate replacement is strongly recommended:

 plastic deformation (distortion) by previous impact stress,  cracks,  Damage to the edge seal,  immersion of cooling agent in the composite structure,  destroyed or damaged window (coating) on the workspace or operator position.

Model G0877 (Mfd. Since 02/19)

11.3.2 Cleaning electrical cabinet

Although the electrical cabinet is constructed to shut off external air, foreign particles such as dust and dirt may enter the cabinet when the door is open.

Accumulation of foreign particles on the printed circuit boards or other electronic components could cause machine malfunction.

Clean the inside of the electrical cabinet regularly.

Remove dust inside electrical cabinet with a vacuum cleaner. Do not use compressed air to clean inside the electrical cabinet.

Never touch printed circuit boards or parts around the connector. Also avoid shock on these parts.

It is recommended to clean the electrical cabinet every 1000 operating hours.

11.4 Interlock switch sliding door

The interlock switch can be mechanically unlock for repair and maintenance purposes. Perform a safety check if you have set the interlock switch back to the ground state. on page 17

11.4.1 Drain compressed air service unit

The filtration of water and other impurities in the compressed air is automatic when compressed air flows through the maintenance unit.

If the water level of the filter housing exceeds the maximum limit, the water enters the pneumatic equipment and cause damage.

Check the water level daily and drain the water level in the filter when needed.

Model G0877 (Mfd. Since 02/19)

11.5 Cooling lubricants and tanks

CAUTION!

The cooling lubricant can cause diseases. Avoid direct contact with cooling lubricant or parts covered in cooling lubricant.

Cooling lubricant circuits and tanks for water-cooling lubricant mixtures must be completely emptied, cleaned and disinfected as needed, but at least once per year or every time the cooling lubricant is replaced.

If fine chips and other foreign matters are accumulated in the coolant tank, the machine can no longer be correctly supplied with coolant. Furthermore, the lifetime of the coolant pump is reduced.

When processing cast iron or similar materials generating fine chips, cleaning the coolant tank more often is recommended.

Limit values

The cooling lubricant must be replaced, the cooling lubricant circuit and tank emptied, cleaned and disinfected if

 the pH value drops by more than 1 based on the value during initial filling. The maximum

permissible pH value during initial filing is 9.3

 there is a perceivable change in the appearance, odour, floating oil or increase of the bacte-

ria to more than 10/6/ml

 there is an increase in nitrite content to more than 20 ppm (mg/1) or nitrate content to more

than 50 ppm (mg/1)

 there is an increase in the N-nitrosodiethanolamine (NDELA) to more than 5 ppm (mg/a)

CAUTION!

Comply with the manufacturer's specifications for mixture ratios, hazardous substances, e.g. system cleaners, including their permissible minimum use times.

CAUTION!

Since the cooling lubricant escapes under high pressure, pumping out the coolant by using the existing cooling lubricant pump via a pressure hose into a suitable tank is not recommended.

ENVIRONMENTAL PROTECTION

During work on the cooling lubricant equipment please make sure that

 collector tanks are used with sufficient capacity for the amount of liquid to be col-

lected.

 liquids and oils should not be spilled on the ground.

Clean up any spilled liquid or oils immediately using proper oil-absorption methods and dispose of them in accordance with current statutory environmental regulations.

Collect leakages

Do not re-introduce liquids spilled outside the system during repair or as a result of leakage from the reserve tank, instead collect them in a collecting container for disposal.

Disposal

Never dump oil or other substances which are harmful to the environment into water inlets, rivers or channels. Used oils must be delivered to a collection centre. Consult your supervisor if you do not know where the collection centre is.
