SUMICRYSTAL
M46
SUMICRYSTAL PD and PDX are synthetic diamonds
processed into thin prism shapes for use as dressers. These
dressers can be used in automated, high precision dressing
providing reliable performance and longer tool life, as
compared to natural diamonds.
SUMICRYSTAL PD
Characteristics
Revolutionary Elongated Shape
(1) Improved clamp strength prevents diamond pull out.
(2) Consistent cross-section prevents deterioration.
(3) Uniform face orientation promotes stable tool life.
