As with all technical processes, preparation is everything.
Prior to HPT, perform soft machining with a Sandvik Coromant wiper insert to create the best possible conditions for HPT. Correct soft machining equalizes surface topography and stabilizes hardening effects.
It will also permit completely dry HPT and minimize inheriting surface imperfections. Due to the relatively small depths of cut in HPT, close dimensional tolerances in soft machining are one of the keys to HPT process consistency.
