3.3.3 Machine mounting
Anchor-free assembly
Align the CNC machine with a machine spirit level. The slope deviation of all levels must not
exceed 0.04/1000mm.
Adjust the height by screwing in or screwing out of the levelling screw. Screwing in the lev-
elling screw causes that the rubber plate lifts itself as on the drawing from the same ele-
ment.
Fix the height adjustment by the the jackscrew with the help of the counternut.
Check the alignment of the machine after a few days of usage.

Anchored assembly
Use the anchored assembly in order to attain a firm connection to the ground. An anchored
assembly is always reasonable if parts are manufactured to the maximum capacity of the CNC
machine.
ATTENTION!
An insufficient rigidity of the substructure leads to superposition of vibrations between
the CNC machine and the substructure (natural frequency of the 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.
Check the correct alignment of the machine after a few days of usage.
3.3.4 Corrosion protection
A corrosion protection is applied on the machine table and on the guiding surfaces for trans-
port and storage. Remove the anti-corrosive agent from the CNC machine before first com-
missioning. Therefore, we recommend you to use paraffin.
