Drawbar Retention Force
The tool holder is clamped in the spindle by the gripping action of the col-
let fingers on the tool holder retention knob.
A clamp force of 1980kg (4366lb) is generated by a set of disc (Belleville)
springs mounted on the drawbar. This design provides a positive mechan-
ical clamping mechanism. The normal state of the spindle is clamped.
Makino recommends checking the retention
force periodically to ensure that the clamping
mechanism is providing the proper force. Loss
of retention force is the result of weakened or
cracked disc springs.
Retention force is measured with a calibrated
gage called a “Drawbar Dynamometer” (
). These gages vary widely in price and
quality. An acceptable source for this gage is
listed below, contact them for price and deliv-
