Our high concentrate and random setting technology achieves long tool life and high accuracy. Our unique precision electroforming and precision machining technologies enables us t o achieve any kind of complicated pro le. Also, we offer wider variety of option.
With our precise diamond setting technology, concentration can be controlled as per your request. Higher electroforming technology as same as RZ type can achieve high precision grinding with maintaining good sharpness. This is also suitable for large-sized plunge dressing.
precision powder metallurgy technology and high-precision diamond lapping technology works greatly for dressing that requires sharpness. It is effective even for traverse dressing.

Peripheral Speed Ratio
The Spec optimized for sharpness by regular array or lower concentration treatment. Especially it works greatly for reducing dressing load, chatter and burning issue in wider grinding wheel.
High-precision specialized spec that achieves high pro le accuracy as well as ne sharpness. Excellent shape stability supports quality control of workpieces.
The spec which designed for maintaining sharpness as well as improving wear resistance. It performs high pro le accuracy even in high-load dressing with CBN wheels and hard grinding wheels.
Vr (Speed)=R.P.M x O.D x π Vs (Grinding wheel peripheral speed) =Grinding wheel revolution (min -1 ) ×O.D.×π * In case of up dress, please add "-", minus, to the number after the calculation.

This is standard dressing method that uses same profile as a parts to be ground.
Profile grinding at end face without burn mark is available. High dressing ability spec such as Optimard Spits is highly recommended.
