1.13 Rescuing persons in dangerous situations after the CNC retrofitting
If the machine was subject to a subsequent retrofitting with CNC controlled drives, the following
additional dangerous situations such as squeezing and sticking of parts of the body may result
hereof.
If the machine had been switched off in a dangerous situation using the Emergency-Stop function, it is no longer possible to actuate the axis by means of the electromotor in order to rescue
the squeezed person.
In this case it is necessary to release the machine manually.
This releasing of the X-axis and of the Y-axis is performed using an appropriate tool (e.g. a flat
wrench), which is inserted on the hexagon nut at the shaft end which is opposite to the drive.
It is only possible to release the Z-axis using a separate handwheel which is inserted on the free
shaft end of the manual crank drive.
WARNING!
It is imperatively necessary that the tools are available to release the machine in case of a
dangerous situation.
Therefore, keep the wrench and the handwheel always in close proximity of the CNC con-
trolled machine.

2.11 Emissions
The emission of the drilling-milling machine is below 76 dB(A). If the drilling-milling machine is
installed in an area where various machines are in operation, the acoustic influence (immission)
on the operator of the drilling-milling machine may exceed 85 dB(A).
INFORMATION
This numeric value had been measured on a new machine under conventional operating conditions. Depending on the age or wear of the machine, the noise behavior of the machine might
change.
Furthermore, the extent of the noise emission is also depending on manufacturing
influence factors, such as speed, material and clamping conditions.
INFORMATION
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 depe nding on the overall
stress caused by noise and on the basic limit values.
We generally recommend using a sound and ear protection.

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 the work spindle without using the
draw-in rod are not allowed for milling operations. The cone connection shou ld be
released by the lateral pressure. Injuries may be caused by parts flying off.
The mill head is equipped with a draw-in rod M10.
Remove the cover.
Clean the seat in the milling spindle /
spindle sleeve.
Clean the taper of your tool.
Insert the tool into the holding fixture /
spindle sleeve.

ATTENTION!
When installing a cold morse taper into a heated-up machine those MT seats tend to
shrink on the morse taper contrary to the quick-releaser 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.
“Optional accessory“ on page 24
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 another
appropriate clamping tools such as clamping claws.
4.7 Changing the speed range
ATTENTION!
Wait until the drilling-milling machine has come to a complete halt before changing the
speed using the gear switch.
Select reduction stage.
H = rapid
L = low
Adjust the speed with the potentiome-
ter. The speed and thus the cutting
speed are depending on the material of
the workpiece, the milling cutter diameter and the cutter type.

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. Tabellenbuch Metall,
Europa Lehrmittel, ISBN 3808517220).
The required speed is calculated as follows:
n = speed in min
-1
(revolutions per minute)
V = cutting speed in m/min (meters per minute)
d = tool diameter in m (meters)

4.8.2 Standard values for speeds with HSS – Eco – twist drilling
• 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).

The mill head with column can be mounted on the lathe bed of the D240 and
D280. An adapter is required to fix it. It is
not possible to fix it on the lathe saddle.
The adapter is dimensioned in a way that
the center of the lathe chuck can be
reached with the centre of the milling
spindle (line tailstock - lathe chuck).
“Optional accessory“ on page 24
Due to the manufacturing tolerances of
cast parts and the manufacturing tolerances of two different machines, it is
however not possible to exactly reac h the
centre. The adapter might be too short or
too long.
If required, the adapter has to be milled or
provided with dummy sheets. When using
dummy sheets, the complete surface
needs to be filled.
Fig.4-15: Adapter
When aligning the column with the mill head mounted onto it, we recommend to disassemble
the mill head from the column in order to reduce the holding force of the column. Unscrew the
stud screw (screw) position 266. Disassemble the mill head from the column by completely loosening the clamping screw and the guide screw and pull off the mill head.
Check the alignment (right angle horizontal and vertical) of the column regarding th e reference
level at the lathe bed.
INFORMATION
In order to avoid the efforts of alignment when retrofitting it at a later time, we recommend you to
provide the column and the adapter as well as the adapter and the lathe bed with aligning pins.
If required, also pin the column to the cross table before disassembling the column. It is most
suitable to use hardened straight pins of 8mm or 10mm according to DIN 6325 and an adjustment tolerance field m6 (e.g. DIN 6325-8 m6 x 30). These straight pins have a round cap on
one side which simplifies to stick the parts together. The holes have to be predrilled imperatively
about 0,2mm smaller in the assembled status and have to be grinded with a reamer also in the
assembled status. Therefore, ma ke sure to use a new spiral d rill with a diameter of 7.8mm for
the straight pins of 8mm.

Spindle nuts
Readjust
An increased clearance in the spindles of the crosstable can
be reduced by readjusting the spindle nuts. Refer to spindle
nuts position 66 and 71
The spindle nuts are readjusted by reducing the flank of
screw thread of the spindle nut with an adjusting screw. By
readjusting a smooth running move over the whole toolpath
is to be assured, otherwise the wear by friction between
spindle nut /spindle would increase considerably.

5.4 Setting instructions control
Please find below a description to set the operating parameters, if required after replacement of
the control and of the motor.
Vmax
This is the potentiometer to set the maximum possible speed of the motor.
The speed of 3000 min
-1
must not be exceeded since the spindle bearings and your tools might
get damaged.
Vmin
This is the potentiometer to set the minimum possible speed of the motor. Make sure that the
speed does not fall below 50 min
-1
.
With reduced speed also the torque (power of the motor) and the cooling will reduce!
Torque
This is the potentiometer to set the torque when readjusting the motor. Depending on the
application set the value by which the the control will readjust. If you require less readjustment,
turn the potentiometer one to two turns in direction "minus". For a larger readjustment, turn the
potentiometer in direction "plus". For thread cutting we recommend little torque.
Slope
This is the potentiometer to set the acceleration time of the motor at the moment when it starts
turning. If you require a smoothe r ramp, turn the potentiometer in direction "plus". In order to
achieve a steeper ramp, turn the potentiometer in direction "minus".
CL
This is the potentiometer to set the current limiting as an o verload protection for the motor. The
current limiting is set by the manufacturer and must not be changed in any way.
General information
The control is charged with high constant-voltage currencies. Please make imperatively sure
that the housing will only be opened up in the idle status. Furthermore, make sure that any
settings are only being performed when the housing is closed.
The spindle trimmers of the potentiometer are designed with 12 gears. This means in order to
achieve the corresponding minimum or maximum value, the spindle trimmer needs to be turned
12 times. Due to this high number of gears of the spindle trimmer it is possible to perform a very
sensitive setting over the corresponding potentiometer.

Any services which OPTIMUM GmbH or one of its agents performs in order to fulfill in the
frame of an additional guarantee are neither an acceptance of the defects nor an acceptance of its obligation to compensate. Such services do neither delay nor interrupt the warranty period.
Place of jurisdiction among traders is Bamberg.
If one of the above mentioned agreements is totally or partially inefficient and/or null, it is
considered as agreed what is closest to the will of the warrantor and which remains in the
framework of the limits of liability and warranty which are predefined by this contract.
