Ch 7 GENERAL DESCRIPTION
GT 326-E
7.13 TWO POSITION SYSTEM (Option for Non-Guide Bushing)
An adjustable 2-position retraction with dual safety switches can be installed to accommodate
non-guide bushing applications with sliding headstock machines (Swiss style).
Benefits :

This option reduces the unsupported gap between the front of bar feeder and back of
headstock when the headstock is working in chucker mode (non-guide bushing).

Better bar support => maintains rpm performance

Reduced pusher length outside the bar feeder (reduced overhang)
Safety:

Reduces or eliminates danger of bar and pusher collet separation in an open area due
to excessive vibrations

2-Positions are confirmed by safety switches (SQ10 and SQ10A).
Note: The CNC should be prepared to receive a signal from the bar feeder confirming Guide
Bushing mode (bar feeder adjusted back) or Non-Guide Bushing mode (bar feeder in the most
forward position).
