2.2 Proper use
WARNING!
In the event of improper use of the add-on pieces, it
• will endanger the user,
• will endanger the machine and other material property of the operator or user,
• may affect proper operation of the machine.
The add-on pieces as conversion kit are provided for the computer-aided - CNC, Computerised
Numerical Control - milling operations of your machine.
The drive of the step motors may also be performed manually with a control unit
(potentiometer).
Improper
use! The milling machine with the adapter kit must only be placed and operated in dry and ventilated
rooms.
The hand wheels need to be disassembled.
If the adapter kit is used in any way other than described above or modified without approval of
the company Optimum Maschinen Germany GmbH the adapter kit is no longer properly used.
We do not take liability for any damage caused by improper use.
We would like to stress that any modifications to the construction, or technical or technological
modifications that have not been authorised by Optimum Maschinen GmbH will also render the
guarantee null and void.
2.3 Required auxiliary material
Means of shaft lock-down device "Loctite 648, join the shaft".
The designation of the parts in the assembly description corresponds to the numbering of the
packing list.
In order to degrease the shaft, a cleaner for brakes or a corresponding cleaning agent is
required.
A tenacious grease e.g. Mobilux 3 or a corresponding lubricating grease serves to grease the
bearings.
Required tools:
lubricating oil for thread cutting, twist drill 5mm,
counter sink; screw tap M6, manual drilling machine, calliper gauge,
a set of Allen keys, set of fork wrenches, blow-back proof plastic tip hammer,
box wrench 13mm, screw driver, tongs, chipping spanner,
soldering iron with accessories, abrasive cloth, small chisel (you may also use a small screw
driver).

3.1 Assembly X axis
3.1.1 Disassemble the self-locking nut and
the shim of the left handwheel of the X
axis.
3.1.2 Remove the handwheel with a blow-
back proof plastic tip hammer with
smooth knocks. Turn the handwheel at
the same time.
Fig.3-1: Handwheel on the left
3.1.3 Remove the rivet of the nonius with a
hammer and a small chisel (or use a
screw driver as chisel).
3.1.4 Grind off the relief with an abrasive
cloth in order to facilitate the mounting
of the assembly ring.
Fig.3-2: Grinding
INFORMATION
The axial deep groove ball bearing of the milling machine table has to be disassembled on the
right side and reassembled on the left side. The bushing of the milling machine table has to be
disassembled on the left side and reassembled on the right side.

3.1.5 Modify the axial deep groove ball bea-
ring and the bushing.
3.1.6 Shift the assembly ring (No. 3) with the
slot downward on the relief - if required
- with slight beats of the hammer with a
blow-back proof plastic tip hammer.
3.1.7 Beat on the assembly ring until a small
collar is being formed (2 to 3mm). In
this place the housing will centre later
on.
Fig.3-3: Assembly ring
3.1.8 Do not clamp the assembly ring yet! (The ring should be positioned as parallel as possible).
3.1.9 Mount the pulley of the toothed belt
(No. 6) on the shaft.
3.1.10 Fasten the pulley of the toothed belt
with the nut and shim of the handwheel.
3.1.11 Do fasten the nut too much otherwise
the shaft might clamp.
3.1.12 Check if the shaft is running well by
turning the pulley of the toothed belt.
Fig.3-4: Pulley of the toothed wheel X axis
3.1.13 If the shaft is too tight, detach the nut a little.
3.1.14 Uniformly fasten the housing (No. 2)
with the screws (No.12) on the assem-
bly ring.
3.1.15 The housings differ in the diameter of
the through hole. The hole for the Z
axis is a little larger.

CAUTION!
Do not fasten the self-locking screw with force. Allow enough clearance for the spindle
(air, clearance).
3.2.3 Mount the pulley of the toothed belt
(No. 6) on the shaft and fasten it with
the self-locking nut and the shim of the
handwheel.
3.2.4 Control if it is running well by turning
