ER-32 Collet Adapter Kit
This adapter permits use of ER-32 series collets on on lathes with 1-1/2" threaded spindles. The ER series collet is a parallel closing design available from most industrial suppliers. Front closing collets permit full utilization of through hole in spindle.
The kit comes with material, drawings and instructions. Included is enough material to produce a duplicate of your spindle nose to serve as a thread gauge. Machining includes internal and external threading and accurate angle setting for machining from the compound slide. The kit also provides both material and drawings for machining a complete, though not standard ER nut. If you prefer to do a little less machining, dimensions are also included for the ER specification so that a standard nut may be purchased from any of the major industrial suppliers.
