Dresser Blank SUMICRYSTAL PD PD / PDX
■ General Features SUMICRYSTAL PD and PDX are single-crystal synthetic diamonds processed into thin prism shapes for use as dresser blanks. Their stable performance and long tool life improve dressing precision.
M
SUMICRYSTAL PD ■ Features ● Revolutionary Elongated Shape (1) Improved retention strength prevents diamonds from falling out. (2) Consistent cross-section prevents deterioration. (3) Uniform crystal orientation promotes stable tool life.
SUMICRYSTAL PDX ■ Features ● Compared to conventional tools (PD), the product has different face crystal orientation. (1) Crystal orientation (211) provides better tool life than conventional PD blanks. (2) Parallel abrasive resistant faces (111) facilitate blank setting
during manufacturing of dressers. ■ Standard Cat. No. (PDX)
