WARNING!
In the event of improper use, the mill drill

 there may be a risk to the staff,
 the mill drill and other material property of the operating company will be endan-

gered,

 the correct function of the mill drill may be affected.

The mill drill is designed and manufactured to be used for milling and drilling cold metals or
other non-flammable materials or materials that do not constitute a health hazard by using com­mercial milling and drilling tools.

The mill drill must only be installed and operated in a dry and well-ventilated place. If the mill
drill is used in any way other than described above, modified without the approval of the com­pany Optimum Maschinen Germany GmbH then the mill drill is being used improperly.

We will not be held liable for any damages resulting from any operation which is not in accord­ance with the intended use.

We would like to stress that any modifications to the construction or technical or technological
modifications that have not been authorised by the company Optimum Maschinen Germany
GmbH will also render the guarantee null and void. It is also part of proper use that

 the maximum values for the mill drill are complied with,
 the operating manual is observed,
 the inspection and maintenance instructions are observed.

 "Technical data“ on page 15

1.4 Reasonably foreseeable misuses

Any other use as the one determined under the "proper use" or any use beyond the described
use shall be deemed as not in conformity and is forbidden.

Any other use has to be discussed with the manufa cturer.
It is only allowed to process metal, cold and non-inflammable materials with the milling-

machine.
In order to avoid misuses it is necessary to read and understand the operating instructions

before the first commissioning.
The operators must be qualified.

1.4.1 Avoiding misuses

 Use of suitable cutting tools.
 Adapting the speed adjustment and feed to the material and workpiece.
 Clamp workpieces firmly and vibration-free.

OPTIMUM

MASCHINEN - GERMANY

Version 3.1.8 dated 2015-1-27 Page 9Original operating instructions

BF20V US

ATTENTION!
The workpiece is always to be fixed by a machine vice, jaw chuck or by another

appropriate clamping tool such as for the clamping claws.
WARNING!

Risk of injury caused by workpieces flying off.

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

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

surface quality.

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

It is recommended:

 Insert the drill in a way that it is exactly positioned between the three clamping jaws of the

quick action chuck.

 Clamp and mills by means of the collet chuck and the corresponding collets.
 Clamp end face mills by means of shell end mill arbors.

When drilling make sure that

 the suitable speed is set depending on the diameter of the drill,
 the pressure must only be such that the drill can cut without load
 in case of too strong pressure the drill will get worn early or even might break resp. get

jammed in the hole. If the drill gets jammed immediately stop the main motor by pressing
the emergency stop button,

 for hard materials, e.g. steel, use commercial cooling / lubricating agents,
 generally always drive the turning spindle out of the workpiece.

ATTENTION!
Do not use the quick action drill chuck for milling tools. Never clamp a milling cutter into

the quick action drill chuck. Use a collet chuck and the corresponding collets for the end
mill.

When milling make sure that

 the corresponding cutting speed is selected,
 for workpieces with normal strength values, e.g. steel 18-22 m/min,
 for workpieces with high strength values 10-14 m/min,
 the pressure is selected in a way that the cutting speed remains constant,

for hard materials commercial cooling / lubricating agents are used.

1.5 Possible dangers caused by the mill drill

The mill drill was built using the latest technological advances.
Nonetheless there remains a residual risk, since the mill drill operates with

 at high speeds,
 with rotating parts and tools,
 with electrical voltages and currents.

2.11 Emissions

The emission of the mill drill is below 80 dB(A).
If the mill drill is installed in an area where various machines are in operation, the noise expo­sure (immission) on the operator of the mill drill at the working place may exceed 80dB(A).

INFORMATION

This numerical value was measured on a new machine under proper operating conditions.
Depending on the age respectively on the wear of the machine it is possible that the noise
behaviour of the machine changes.

Furthermore, the factor of the noise emission is also depending on manufacturing influencing
factors, e.g. speed, material and clamping conditions.

INFORMATION

The mentioned numerical value is the emission level and not necessarily a safe working level.
Though there is a dependency between the degree of the noise emission and the degree of the

noise disturbance it is not possible to us e it reliably to determine if further precaution measures
are required or not.

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

 Characteristics of the working area, e.g. size or damping behaviour,
 Other noise sources, e.g. the number of machines,
 Other proce sses taking place in the proximity and the period of time during which the oper-

ator is exposed to the noise.

Consult OSHA, state and local regulations in order to determine compliance, dangers and risks
to the operator.

CAUTION!
Depending on the overall noise exposure and the basic limit values the machine

operators must wear an appropriate hearing protection.
We generally recommend to use a noise protection and a hearing protection.

 Fix the load lifting gear around the mill drill head. Use a lifting sling for this purpose.

lifting sling.

 Firmly clamp all clamping levers on the mill drill before lifting the mill drill.
 Make sure that the load attachment does not cause damage to components or paint.

3.4.3 Assembly

 Check if the underground of the mill drill is level using a spirit level.
 Check if the underground is sufficiently stable and rigid. The total weight is 440 Kg./ 227 lbs.

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

the vibrations of the mill drill and of the underground (natural frequency of components).
Critical speeds and moves in the axis with displeasing vibrations are rapidly achieved in
case of insufficient rigidity of the whole system and will lead to bad milling results.

 Place the mill drill on the provided underground.
 Fix the mill drill in the provided through-holes on the machine foot.

WARNING!
The condition of the underground and the fixing type of the machine foot to the

underground must be in a way that it can bear the loads of the mill drill. The
underground must be level. Check if the underground of the mill drill is level using a
spirit level.

Fix the foot of the mill drill to the stand with the provided through-holes. When using an option­ally available machine stand, it also needs to be anchored safely and firmly. We recommend
you to use shear connector cartridges resp. heavy-duty anchors.

4.5 Inserting a tool

4.5.1 Installation

CAUTION!
When milling operations are performed the cone seat has to be fixed always to the draw-

in rod. Any cone connections with the taper bore of t he work spindle without using the
draw-in rod are not allowed for milling operations. The cone connection should be
released by the lateral pressure. Injuries may be caused by parts flying off.

The mill head is equipped with a 10mm draw-in rod.

 Remove the cover.
 Clean the seat in the milling spindle /

spindle quill.

 Clean the taper of your tool.
 Insert the tool into the holding fixture /

spindle quill.

Fig.4-4: Mill drill head

 Screw the draw-in rod into the tool.
 Tighten the tool with the draw-in rod

and hold the spindle onto the end

support with a key.

Fig.4-5: Mill drill head

4.5.2 Disassembly

 Hold the spindle thrust bearing with a wrench and loosen the draw-i n rod 2-3 turns. Tap top

of draw rod with hammer to loosen the tool from the cone. Turn the draw-in rod further, so

that the tool is released completely from the cone.

ATTENTION!
When installing a cold Morse taper into a heated-up machine those MT seats tend to

shrink on the Morse taper versus quick-release tapers.

4.5.3 Use of collet chucks

When using collet chucks to hold milling tools, a higher operation tolerance can be achieved.
The exchange of the collet chucks for a smaller or larger end mill cutter is done in a simple and
rapid way and it is not necessary to disassemble the complete tool. The collet chuck is pressed
into the ring of the swivel nut and has to rest there by itself. The milling cutter is clamped by fas­tening the swivel nut on the tool.

Make sure that the correct collet chuck is used for each milling cutter diameter, so that the
milling cutter may be fastened securely and firmly.

4.6 Clamping the workpieces

CAUTION!
Injury by parts flying off.

The workpiece always needs to be fixed by a machine vice, a jaw chuck or by other
appropriate clamping tools such as clamping claws.

4.7 Changing the speed range

ATTENTION!
Wait until the mill drill has come to a complete halt, before performing any changes on

the gear switch.

 Select gear level

H = rapid
L = low

 Adjust the speed with the

potentiometer. The speed and
thus the cutting speed
depends on the material of the
workpiece, the milling cutter
diameter and the cutter type.

Fig.4-6: Drilling and milling head

4.8 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 optimised.

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 at higher
speeds than with tools made of high-alloyed 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 (e.g. Machinery's
Handbook ISBN 0-8311-2424-5, Insert Pgs. 30a & 30b (attached)).

The required speed is calculated as follows:

H = rapid

L = low

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. 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
authorised distributors.

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.
