6 TURN PLUS 330
6.16.9 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.
TURN PLUS does not support retracting the tailstock and does not
check the setup used.
Precondition for shaft machining: The workpiece is clamped at
spindle and tailstock.
Danger of collision!
TURN PLUS does not monitor for collisions during transverse
machining or machining operations on the end face.
Protective zones for drilling and milling operations
■ TURN PLUS machines drilling and milling contours on the end face
(front and rear face) provided that the following conditions are
fulfilled:
■ The (horizontal) distance from the end face must be greater than
5 mm, or
■ The distance between chucking equipment and drilling/milling
contour must be
greater than SAR (SAR: see machining parameter 2).
■ If jaws are used for clamping the shaft at the spindle, TURN PLUS
accounts for the cutting limitation (SB).

Separation point (TR)
The workpiece is divided into 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
separation points on outside corners.
Tools for machining the
■ Area on front side: Main machining direction – Z; or primarily ”left”
recessing or tapping tools, etc.
■ Area on rear side: Main machining direction + Z; or primarily ”right”
recessing or tapping tools, etc.
