The Coborn PG3B is a manual machine with programmable pivot and has air bearings for both the pivot and the water cooled-wheel spindle. The machine is designed for polishing low or controlled waviness SCD tools and facetted, coned and radiussed indenters.
The PG3B is still one of Coborn’s most popular machines and we currently have PG3B in our demo room. Please get in touch if you would like to book an appointment for a machine demonstration.
