Installation On The Lathe; Preparing The Lathe; Preparing The Chuck For Mounting - Bison 2500 Instruction Manual

6. installation on tHe latHe

6.1. preparing the lathe

The machine safety control sytem should prevent
turning on the spindle rotation, while the pressure
distributor is ‚under pressure'.
The lathe should be equipped with a special ring or
bracket, supporting the distributor in centric and non-
contact position with the chuck, as well as the adapter
plate (for chuck mount). The operator should get these
elements by himself or order.
Stiffly and permanently mount the ring or brackets
onto the lathe spindle or spindle bearing cover; the
adapter plate on the spindle end. The adapter plate
requires the I.D. hole of Ø14mm - as far as the safety
valve pin appears (dimensions ‚L' and ‚F' according to
Fig. 1. and Tab. 2.).
After the mount, the ring or brackets, and adapter
plate should meet the conditions indicated in Fig. 3.,
dimensions according to Tab. 2.
