7.7 Torque / clamping force / holding force too low

Possible cause

Corrective action

Toolholder pressed in wrong angle
(clamping area is deformed).
Toolholder has been over-pressurized,
which means charged with too much
pressure (clamping area deformed).

Send the toolholder to SCHUNK for inspection/
repair.
Observe TRIBOS pressure table (do not exceed
max. pressure).

Shank does not have the required
tolerance h6.
Tool shank is under-dimensioned (< h6).

Use tool shank with tolerance h6.

Minimum shank clamping depth was not
observed.

Observe minimum shank clamping depth (see
operating manuals TRIBOS polygonal
toolholder).

Lubricant film on tool shank and/or on
clamping area.

De-grease and clean clamping area and tool
shank.

Toolholder and tool were inserted with
wrong (too high) cutting data.

Adjust cutting data/cutting values.
