TURN PLUS | Machining information

Shaft machining

For shafts, TURN PLUS supports rear-face machining of outside
contours in addition to standard machining processes. This enables
shafts to be completely machined using one setup. You can select
the clamping type for the Shaft machining AWG (1: Shaft/chuck
or 2: Shaft/face driver) in the V input parameter in the chucking
equipment dialog.
Precondition for shaft machining: The workpiece is clamped at
spindle and tailstock.
Danger of collision!
In AWG submode and during machining on the front or rear face,
the control does not automatically monitor for collisions, and
retraction of the tailstock is not supported. Danger of collision
during machining!
In the Simulation submode, test the NC program with the
graphic.
Edit the NC program if required
Separation point TR
The Separation point TR divides the workpiece into a front and
rear area. If no Separation point has been specified, TURN PLUS
sets a separation point at the transition from the largest to a
smaller diameter. Position the
corners.
Tools for machining the
Area on front side: Main machining direction – Z; and primarily
left recessing or tapping tools, etc.
Area on rear side: Main machining direction + Z; and primarily
right recessing or tapping tools, etc.
Setting/changing the Separation point:
