general principles
Check of cutting insert seat condition:
Before clamping of new cutting insert or change of edge (rotation of
cutting insert) is necessary to purge the seat, check its condition or
condition of anvil and wedge (especially the damage under the corner
of cutting insert).
Check and maintenance of clamping parts:
The checking of clamping parts – clamping levers, screws, wedges,
clamps. Use only undamaged parts, use the original parts only – you
find them in the catalogue. Regularly lubricate the threads and binding
surface of screws, for example by heat-resistant lubricant (Molyko G). For
mounting and disassembling, use only screw drivers and wrenches as per
our catalogue or recommended by the tool producer. Pay attention to the
right tightening (proportional), we recommend to use torque wrench.
Check of tightening:
At tightening check the fitting of cutting insert on the whole binding surface
and fitting in radial and axial direction. Cutting inserts and tools must be
always clean and undamaged.

POOR SURFACE QUALITY
Description and cause:
Causes are various, depend on work piece material,
cutting conditions (feed and cutting speed), cutting edge
condition, extend and type of wear, condition and rigidity
of machine-tool-work piece.
- wrong choice of tool
- wrong chip thickness
- wrong cutting speed
- coolant is needed
- high feed rate
Troubleshooting:
- use wiper insert
- use cutting insert with the right geometry
- reduce the feed rate
- change (usually increase) the cutting speed
- use a coolant
- improve the stability of cutter and work piece
- change the chip cross section
