1.3 Reasonably foreseeable misuse

Any other use or any use beyond the use described under "Proper use" is regarded as
improper use and is forbidden.

If it is intended to use the device in any othe r wa y as de sc rib ed above, it is necessary to consult
the manufacturer.

It is only allowed to work metallic, cold and non-flammable material using the milling machine.
In order to avoid misuse, it is necessary to read and understand the operating instructions

before the first commissioning.
The operators must be qualified.

1.3.1 Avoiding misuse

 Using suitable cutting tools.
 Adapting speed settings and feed on the material and on the workpiece.
 Clamp the workpiece firmly and vibration-free.

ATTTENTION!
The workpiece must always be fixed in a machine vice, jaw chucks or any other suitable

clamping tool such as e.g. clamping claws.
WARNING!

Injuries due to workpieces flying off at high speed

Clamp the workpiece in the machine vice. Make sure that the workpiece is firmly clamped in the
machine vice resp. the machine vice is firmly fixed on the machine table.

 Use of cooling and lubricating agents in order to increase the durability of the tool and to

improve the surface quality.

 Clamp the cutting tools and the workpieces on clean clamping surfaces.
 Sufficiently lubricate the machine.
 Correctly set the bearing clearance and guidance.

It is recommended to:

 Use the drill in a way that it is exactly located between the three clamping jaws of the quick

action chuck.

 Clamp the end mill by means of the collet chuck and the corresponding clamping collets.
 Clamp the end face mill by means of the end mill arbor.

When drilling, please observe that

 It is necessary to set the suitable speed depending on the diameter of the drill,
 The press-on must only be as intense that the drill can cut on no-load,
 If the press-on is too intense, it might result in early tool wear perhaps even tool fracture

resp. jamming in the drill hole. If the tool gets jammed, immediately stop the main drive
motor by actuating the emergency-stop button,

 For hard materials, e.g. steel, it is necessary to use commercial cooling/lubricating agents,
 Generally always back out the tool from the workpiece while the shaft is turning.

ATTENTION!
Do not use the quick action chuck as milling tool. Do not clamp the milling tool in the

quick action chuck in no case. Use a collet chuck and the corresponding collets for the
end mill.

The mentioned numerical value is an emission level and not necessarily a safe
working level.

Unless the degree of noise emission and the degree of noise disturbance are depending on
one another it is not possible to use it in order to reliably determine if it is necessary to take fur­ther preventive measures or not.

The following factors influence the actual degree of the noise disturbance of the
operator:

 Characteristics of the working chamber, e.g. size or damping behavior,
 Other noise sources, e.g. the number of machines,
 Other processes proceeding nearby and the period during which the operator is exposed to

the noise.

Furthermore, the admissible pollution level may be different from one country to another due to
the national regulations.
This information regarding the noise emission should allow the operator of the machine to per­form a better evaluation of the endangerments and risks.

CAUTION!
The machine operator has to wear an appropriate ear protection depending on the

overall stress caused by noise and on the basic limit values.
We generally recommend using a sound and ear protection.

3.4 Installation and assembly

3.4.1 Site requirements

Organize the working space around the drilling-milling machine according to the local safety
regulations.

INFORMATION

In order to provide for good functionality and high machining accuracy as well as long durability
of the machine the site should fulfill certain criteria.

Observe the following items:

 The device must only be installed and operated in dry ventilated places.
 Avoid places nearby machines generating chips or dust.
 The site has to be vibration-free, i.e. at a distance from presses, planin g machines, etc.
 The substructure has to be appropriate for drilling-milling machine. Also make sure that the

load bearing capacity and the evenness of the floor are appropriate.

 The substructure has to be prepared in a way that possibly used coolant cannot penetrate

into the ground.

 Protruding parts such as stops, handles, etc. need to be secured by measures provided by

the customer if necessary in order to avoid dangers for persons.

 Provide sufficient space for assembly and operating staff as well as for material transport.
 Also allow for accessibility for setting and maintenance works.
 Make sure that the mains plug of the turning machine is freely accessible.
 Provide for sufficient illumination (minimum value: 500 lux, measured at the tool tip). In case

of little intensity of illumination provide for additional illumination i.e. by a separate workplace
illuminator.

INFORMATION

The mains plug of the drilling-milling machine has to be freely accessible.

3.4.2 Load suspension point

WARNING!
Danger of crushing and overturning. Proceed with extreme caution when lifting,

installing and assembling the machine.

 Secure the load-suspension device around the drill-mill head. Use a lifting sling for this pur-

pose.

 Clamp all the clamping levers at the drilling-milling machine before lifting it.
 Make sure that no add-on pieces or varnished parts are damaged due to the load suspen-

sion.

3.4.3 Installation

 Check the horizontal orientation of the base of the drilling-milling machine with a spirit level.
 Check that the foundation has sufficient floor-load capacity and rigidity.

 „Total weight [kg]“ on page 15

ATTENTION!
Insufficient rigidity of the foundation leads to the superposition of vibrations between

the drilling-milling machine and the foundation (natural frequency of components).
Insufficient rigidity of the entire milling machine assembly also rapidly causes the
machine to reach critical speeds, with unpleasant vibrations, leading to bad milling
results.

 Adjust the speed with the potentionmeter.

4.5.1 Selecting the speed

For milling operations, the essential factor is the selection of the correct speed. The speed
determines the cutting speed of the cutting edges which 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 material and on the material of the tool. With
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.

For 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 (e.g. Tabellenbuch Metall, Europa Lehrmittel
ISBN 3808517220).

The required speed is calculated as follows:

n = speed in min
V = cutting speed in m/min (meters per minute)

(revolutions per minute)

• The above mentioned indications are standard values. In some cases it may be advanta­geous to increase or decrease these values.

• When drilling, a cooling or lubricating agent should be used.

• For stainless materials (e.g. VA – or NIRO steel sheets) do not center since 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

Friction during the cutting process caus es hi gh temp er atures at the cutting edge of the tool. The
tool should be cooled during the milling process. Cooling the tool with a suitable cooling lubri­cant ensures better working results and a longer edge life of the cutting tool.

INFORMATION

Use a water-soluble and non-pollutant emulsion as a cooling agent. This can be acquired from
authorized distributors.

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

4.11 Installation on a lathe

The mill head with column can be
mounted on the lathe D240 and D280.
For fastening, an adapter is required. The
adapter needs to be fixed to the engine
bed. It is not possible to fix it to the lathe
slide. The adapter is dimensioned in a
way that the middle of the lathe chuck
should be reached with the center of the
milling spindle (alignment headstock ­lathe chuck).

 „If the machine is cold such as e.g.

directly after having transported the
machine it should be warmed up at a
spindle speed of only 500 1/min for the
first 30 minutes.“ on page 22

Due to the manufacturing tolerances of
castings and the manufacturing toler­ances of two different machines it is,
however, not possible to reach the exact
center. The adapter may be too sh ort or
too long.

If required, the adapter is to be milled off
or equipped with dummy sheets. When
using sheets the complete surface is to be filled.

Img.4-10: Adapter

BF16 Vario GB

OPTIMUM

MASCHINEN - GERMANY

In order to reduce the support expenditure of the column with milling head during the orientation
we recommend you to disassemble the milling head off the column. Unscrew the locking screw
(safety screw) position 266. Disassemble the milling head off the column by completely loosen­ing the clamping screw and the leading screw and stripping off the milling head. (
screw, guide screw“ on page 28)

Control the orientation (90° angle horizontal and vertical) of the column with the reference
planes on the engine bed of the lathe.

INFORMATION

In order to prevent you from having to reorient the milling head when altering later on, we rec­ommend you to provide the column and the adapter as well as the adapter and the engine bed
with alignment pins. If required, pin the column together with the cross table before disassem­bling the column. It would be best if you use hardened straight pins according to DIN 6325 in
8mm or 10mm and a fitting tolerance zone m6. (z.B. DIN 6325-8 m6 x 30). These alignment
pins have a round cap on one side which facilitates pinning together the parts. When assem­bled the boring holes must necessarily be pilot-drilled about 0,2mm smaller and then be rubbed
with a reamer also when already assembled. Therefore use a new twist drill with a diameter of
7,8mm for alignment pins of 8mm.
