Technical Data／Diamond Rotary Dresser
Diamond Rotary Dresser
What is Diamond Rotary Dresser ? A diamond dresser is a diamond tool used for processing (truing / dressing) and molding (forming) to correct dulling, clogging, and peripheral runout of general whetstones and Diamond / CBN wheels to restore their good sharpness. A dresser is a diamond tool for forming general whetstones and CBN wheels. As complex and precise shape accuracy is required for precision automotive parts, high precision bearings, airplane parts and other types of total shape grinding, a high precision rotary dresser is indispensable. Further, the rotary dresser is capable of highly precise and highly efficient profile dressing compared with the stationary dresser.

For Profile Grinding
Used for traverse dressing of grinding wheels.
Used for total forming shape of grinding wheel.
Uses prismatic diamonds that offers consistent sharpness and wear resistance. Excellent for micro- shape machining.
Diamonds set on both shoulders are suitable for processing micro- profile.
This is a double- shouldered radius type using natural diamonds. This type is used for forming wide grinding wheels and for forming a radius around the periphery of the grinding wheel.
This is a Impregnated type with fine diamond grains bonded by sintered metal. It has a long life, but the wider the abrasive grain layer, the worse the cutting ability.
Cup-shaped dresser suitable for dressing small-diameter grinding wheels.

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 profile. 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.
