Material For Dressers

SUMICRYSTAL PD/PDX

SUMICRYSTAL PD and PDX are synthetic single crystal diamonds processed into long prism shapes for use as dressers. Compared to natural diamond blanks, SUMICRYSTAL blanks have stable performance and long tool life, making it possible to improve and automate dressing.
