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.
⑴ Improves clamping strength and prevents the diamond from dropping. crystal orientation of its end face. ⑵ Consistent cross-section prevents performance deterioration. ⑴ The crystal orientation of the end face is (211), resulting in improved tool ⑶ Crystal orientation alignment stablizes tool life. life compared to the previous product PD. ⑵ Since the wear resistance direction is parallel to the (111) face, it is easy to set the blank during dresser manufacturing.
