Frequently Asked Questions

Can the CPX accept headed blanks and grind the neck diameter behind the head?
This should be possible, but the roughing wheel would need to be manually rotated at 90° to grind the neck section.
Can the headstock A-axis actually index and be used as an axis?
Is it possible to only rough grind sections of a blank?
Yes, it is possible to only rough (or finish) grind individual sections on a blank.
What are the specifications for the incoming blanks used on the CPX Linear?
Incoming blanks used on the CPX require a chamfer on the shank end of the blank with a run out of ≤1 micron for best results.
By what means is the Roller on the Top Clamp actuated?
The Roller is actuated pneumatically.
