User Guide
• To maintain a stable and controlled machining
process use constant RPM (G97).
• Each blade is pre-calibrated in laboratory
conditions for an overhang of 100 mm.
• Although the pre-calibration is suitable for a
wide range of overhangs, sometimes fine-
tuning calibration is necessary, depends on the
overhang and clamping rigidity of the machine.
• Before making fine tuning calibration try
to optimize the cutting conditions. First
step should be reducing the RPM. Damping
plates
Fine-Tuning Calibration
For shorter overhangs / more rigid clamping conditions, it
is recommended to increase the compression of the O-ring Distance
by rotating the calibration screw clockwise (make sure between
the distance between the damping plates increases). plates
Calibration
• For longer overhangs / less rigid clamping conditions, it is screw
recommended to decrease the compression of the O-ring by O-Ring
rotating the calibration screw counter clockwise (make sure
the distance between the damping plates decreases).
• The fine-tuning resolution should be about a half-
turn for each 30 mm difference in the overhang.
• To restore the initial setup, use the distance between
the damping plates imprinted on the blade.
