6.6.1) Pneumatic Clamping for the B- und C-Axis of milling head Option 6.6) to increase its stiffness.
In normal operation the rotary axes of the cutter head of a 5-axes machine are permanently position controlled and have therefore a certain amount of elasticity according to the KV factor of the control.
For 3 axes jobs like roughing or tapping etc. it is possible to lock the position of the turning axes B and C via a M command. The holding torque for the B-axis is 600Nm and for the C-axes 1380Nm.
