XYZ Bed Mill Safety, Installation, Maintenance, Service & Parts List Manual
1.0 Safety
1.1 Introduction
Manual mills were traditionally used by skilled machinists. Prototrak was designed to replace these manual machines and at the same time enhance productivity by adding CNC control.
But, unlike Machining and Turning Centres that can be operated even with unskilled staff (in some modes), Prototrak is designed to be used exclusively by skilled or experienced machinists.
The safe operation of the SMX Mill and ProtoTRAK SMX CNC depends on its proper use and the precautions taken by the operators.
1.2 Safe Operating Information
This machine must only be operated by trained and experienced operators. Any other users should first be subjected to a risk assessment by a responsible, trained person.
This machine is designed for the milling of cold metal within the stated capacity of the machine with axes movement occurring by manual use of handwheels, electronic handwheels or CNC control.
This machine must not be used for machining flammable materials (e.g. magnesium, titanium) without undertaking a risk assessment and incorporating any additional safety measures identified.
It is designed to be used in a standard workshop environment only.
It is the responsibility of the employer, machine owner or machine controller to ensure that this machine is installed, operated and maintained in accordance with the Provision and Use of Work Equipment Regulations (1998) or equivalent local regulations.
In particular, the responsible person must:
Undertake a Risk Assessment on the use of this machine, paying particular attention to the
specific characteristics of the Prototrak system, especially:
o Unrestricted operating mode selection o Guarding height and access to the work zone
Generate and apply Safe Operating Procedures for the use of the Prototrak machine Provide any additional training or safeguarding identified by the risk assessment.
All operators and maintenance staff must read and study this Safety, Installation, Maintenance Service and Parts list manual before operating or undertaking any maintenance or repair work on the machine.
Electrical and Mechanical maintenance must only be conducted by trained and experienced machine tool engineers who fully understand the hazards of working with machine tools.
The electrical supply to the machine must be isolated and locked out before undertaking any maintenance or repair work on the machine. Ideally, power should be isolated and locked out at the distribution board supplying the machine. If not possible, isolate and lock out using the machine isolator on the electrical cabinet at the back of the machine.
All operators must read and study the ProtoTRAK SMX CNC Safety, Programming, Operating, and Care Manual (document 25040). The machine must not be operated until operators understand the operation and safety requirements of this machine.
The cutting tool must not be raised above the table guards without additional guarding measures such as a cutter guard.
The guard vision panels must be replaced in accordance with the stated schedule.
When operating this machine, always observe the following safety precautions
Do not operate this machine without knowing the function of every control key, button, knob, or
handle.
Always wear the appropriate personal protective equipment, including safety glasses and safety
shoes.

the machine.
Keep your hair away from moving parts. Wear adequate safety head gear. Never operate any machine tool after consuming alcoholic beverages, or taking strong
medications, or while using non-prescription drugs.
Carry out a COSHH risk assessment and use the correct protection equipment, e.g. barrier
cream/latex gloves, to prevent harm from items such as cutting fluid, lubrication oil and other substances used on the machine.
Always ensure the appropriate guarding is in place for the machinery operation being undertaken. Observe and understand the warning and safety information labels affixed to this machine. Do not attempt to tamper with or override any guarding/safety device fitted to the machine. Keep the working area clear and remove all tools (spanners, etc.) from the machine before you
start the machine running. Loose items can become dangerous flying projectiles.
Stop the machine spindle and ensure that the CNC control is in the STOP mode:
o Before changing tools. o Before changing parts. o Before you clear away the Swarf, oil or coolant. Always use a chip scraper or brush. o Before you make an adjustment to the part, vice, coolant nozzle or take measurements. o Before you open guards. Never reach around a guard to gain access to the part, tool, or
fixture.
Do not use compressed air to remove swarf or clean the machine. Keep work area well lit. Ask for additional light if needed. Be aware that the machine can move unexpectedly so do not lean on the machine while it is
running.
To prevent slippage and personal injury, keep the working area around the machine dry and
clean. Ensure there is no swarf, oil, coolant and obstacles of any kind around the machine.
Avoid getting pinched in places where the spindle, table or guard doors create "pinch points"
whilst the machine is in motion.
For machines fitted with manual handwheels: to prevent injury during powered axes movement,
keep the handle folded inside the hand wheel at all times except when required to hand crank the table.
Securely clamp and properly locate the workpiece in the vice or in a fixture. Use proper tool
holding equipment.
Use the correct tooling for the process being undertaken. Never use damaged or worn tools and
ensure the correct cutting parameters (speed, feed, and depth of cut) are used in order to prevent tool breakage.
Prevent damage to the workpiece or the cutting tool. Never start the machine (including the
rotation of the spindle) if the tool is in contact with the part.
Avoid large overhangs on cutting tools when not necessary. To prevent fires keep flammable materials and fluids away from the machine, hot swarf and
workpieces.
Never change gears when the spindle is rotating Do not rotate the spindle by hand unless the table guard is open. Stop and disconnect the power to the machine before undertaking any machine cleaning or
maintenance

1.5 EC Declaration of Conformity
The manufacturer, Southwestern Industries, declares that the ProtoTrak SMX mills conform to all the relevant provisions of the:
•Machinery Directive 2006/42/EC Low Voltage Directive 2014/35/EU, and •EMC Directive 2014/30/EU
The Technical file is available from XYZ Machine Tools, Woodlands Business Park, Burlescombe, Nr Tiverton, EX16 7LL, United Kingdom.
1.6 Airborne Noise Emissions
The A-weighted emission sound pressure level at the operator’s workstation is 74dB(A).
(Measured in accordance with ISO 3744 with an uncertainty of 2.5dB.)
The figures quoted are emission levels and are not necessarily safe working levels. Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not further precautions are required. Factors that influence the actual level of exposure of the workforce include characteristics of the work room and other sources of noise,. i.e. the number of machines and other adjacent processes. Also the permissible exposure level can vary from country to country. This information, however, will enable the user of the machine to make a better evaluation of the hazard and risk.

2.8 Electrical Connection
The SMX 2500, 3500, 4000 & 5000 require a 400 volts, 3-phase, 50/60Hz supply plus an Earth connection. No Neutral connection is required.
The incoming supply is wired to the machine through the electric cabinet located on the back of the machine. The cable enters the cabinet through a compression gland fitted into the hole in the top of the cabinet. The wires are connected to the incoming isolator. The main ground wire should be fastened to the isolator mounting bracket with the screw provided.
The earth connection to the machine must be a minimum of 10mm2 (copper) due to high earth leakage current (200mA).
DANGER!
The 400 VAC supply should only be wired by a qualified electrician.
2.9 Air Connection
The machines have a PCL/series 19, quick release air connection on the side of the electrical cabinet for the power drawbar (see section 5).
The air preparation unit is fitted with a pressure regulator, factory set to 70 psi, water trap and lubricator.
2.10 Mounting the Display Pendant
The ProtoTRAK SMX display pendant mounts to the pendant arm with four 1/4-20 x ¾ SHCS. There is a locating screw on the pendant arm to help align the pendant with the mounting holes.
CAUTION!
The locating screw in the arm is used for positioning. Keep a hold of the pendant until the
screws are fastened.
If the pendant arm rotates too freely, remove the painted cap on the bracket attached to the column and tighten the hex nut to tension the hinge. Replace the cap.
2.11 Cable Interconnections
All cable interconnections are made at the factory. See Figure 11 for a complete illustration of cable interconnections for all components. If electronic handwheels are fitted, these plug into the two, 15 pin connectors near the top.
Make sure there is sufficient slack in the cables for when the pendant is rotated about the pendant arm. The worst case is when the pendant is all the way forward toward the operator. The following drawing illustrates pendant connectors.
Make sure there is a hardware (option) key plugged into the parallel port of the pendant. This key activates any converters or options ordered. The part # for this key is 22648. The key must be programmed according to the type of machine it is on and the options ordered.
The Machine ID port must have this key or the machine will not run.
CAUTION!
Make sure the main power is turned off on the back of the electrical cabinet before plugging
in the cables.

2.12 Lubrication
2.12.1 Way Lubrication
The auto lube system provides centralised, automatic lubrication for the ways and ballscrews. The lube pump has a 2-litre reservoir and should be kept filled with ISO 32 slideway oil or equivalent.
The pump has an audible alarm for low oil pressure or low oil level.
The pump is factory set to:
Interval Time: 20 min. Discharge Time: 5 sec Discharge Pressure: Approximately 690-1030 kPa (100 – 150 psi)
The interval time and discharge time can be set electronically:
SMX2500:
o Use the buttons on the side of the lube pump:
INT (Interval): this button programs the interval between pumping cycles. Each press of
the button increases the interval by one minute.
DIS (Discharge): this button programs the amount of time the pump will discharge
each pumping cycle. Each press of the button increases the discharge time by one minute.
FEED: this button is used to manually operate the pump. RST: this button tells the pump to discharge for the time programmed.
SMX3500, 4000, 5000:
o Interval time: Use service code 301. o Discharge time: Use service code 302. o Manually cycle pump: Use service code 300. o See section 4.8 for details of accessing Service Codes within the ProtoTrak control.
The lube pump should be operated manually at the beginning of each shift (using the FEED button or code 300).
CAUTION!
Failure to manually activate the pump at the beginning of each day, or allowing the Auto
Lube to run dry may cause severe damage to the way surfaces and ballscrews.
To adjust the amount of Discharge Pressure displayed on the lube pump gauge, loosen the jam nut and turn the adjustment screw located on the top right side of the lube pump while the lube pump is activated.
See Figures 66 to 71 for machine lubrication drawings.
2.12.2 Head Lubrication
Once Each Week:
1. Fill the oil cup on the front of the head with ISO 32. This oil lubricates the quill feed assembly.
2. Fill the oil cup on the right hand side of the head with ISO 32 oil. This oil lubricates the quill
assembly.
3. Extend the quill fully and apply a coating of ISO 32 oil to the outside diameter of the quill.
Every Four Months:
1. Apply a good grade of general-purpose grease through the grease fittings on the back of the head
and on the left side of the head. This grease lubricates the Low range gear set and the feed change gears respectively.
2. Remove X handwheel drive cover and apply general-purpose grease to the drive gears.

3.0 Troubleshooting by Symptom
Use this section to begin the process of resolving a problem. Each symptom type is described in a few words and then more fully described in an explanatory paragraph. Following this, is a chart that directs in the most logical steps.
DANGER!
Some of these checks involve accessing potentially hazardous mechanical or electrical
systems. These checks must only be carried out by competent personnel.
3.1 Problems Relating To Machining Results
3.1.1 Poor Finish
The part finish is marred with scallops or is very rough.
Do the following Service Codes and document values:
Code 33 Software Identification. This is needed if you call Customer Service Code 11 Measures backlash in the system (Only used on Dual Feedback systems) Code 12 Feed Forward Constant Code 127 Measures backlash in the system (not used on Dual Feedback systems) Code 128 Enter backlash compensation
Possible Cause
Check This
Too much backlash entered for code 128 or calculated with code 11.
Verify nothing is mechanically loose and the backlash values are not higher than what physically is in the system.
Machine Tool & Setup problem
Check for any looseness in the setup (Tool, Tool holder, Part, Vice, or Fixture). Check the condition and type of cutter being used, type of material, RPM and Feedrate, etc. See Machine Tool & Setup Section 4.1
Table, Saddle, or Ram Locks are locked
Make sure the Table, Saddle, and Ram Locks are unlocked. Never use gib locks with a CNC machine.
Inadequate or no Lubrication to Ballscrews and Way surfaces
Make sure all the Way surfaces are getting proper lubrication. If not, check to make sure that the lube pump is functioning properly. Also check for any pinched or blocked oil lines. See Lubrication Section 4.1.3
X, Y, and Z-axis Gibs are not adjusted properly
Check the adjustment of the X, Y, and Z-axis Gibs. See X, Y, and Z-axis Gib Adjustments in Section 5.2.1.
X & Y-axis Drive Trains are loose
Check Repeatability using the Repeatability and Positional Accuracy procedure. Step by step, carefully inspect the Drive Train for any looseness. It may be necessary to disassemble and then reassemble the Drive Train. See Mechanical Drive Train (X, Y) Section 4.2
Way surfaces are pocked, scarred, or excessively worn
Visually check the condition of all the Way surfaces. For machines that may have excessively worn Way surfaces you may need to adjust the Gibs in this area. This will affect performance when using the machine outside of this area. Check lubrication to affected areas.
3.1.2 Circles Out of Round
Circles are not round within 0.05 mm TIR over 75 mm DIA. This is best measured by placing a dial indicator in the quill and sweeping around the part.
Note: The typical slideway-milling machine is not capable of achieving more precise results. If more precise circles are required, then it is recommended to use a precision boring head/boring bar.
