CVD diamond dressing tool

Trimming tools generally remove dull ceramic or abrasive particles from the surface of the grinding wheel, in an effort to reduce the grinding temperature and improve the roughness of the workpiece surface, and improve the ability of the grinding wheel to process small tolerance workpieces. Dressing knives also use dry finishing grinding wheels. Historically, most dressing and finishing operations have been fed into a rotating grinding wheel using stationary dressing tools, often made of single crystal diamond or PCD.


Today, many high-productivity grinding operations use rotating CNC dressers or sharp dressing rollers. When one side of the grinding wheel is processing the workpiece, the other side is continuously trimmed at the same time. CNC rotary dressers hold over 100 identical diamonds, these small diamond pieces are mounted on the outside diameter of the dresser to create unique shapes on the grinding wheel.


Separate CVD diamond offers users and producers of dressing tools a number of unique advantages when cutting with a laser. The structure of CVD diamond can be engineered to have high fracture toughness and strength to optimize dressing tool life and dimensional stability.


Because CVD diamond is cut into uniform small pieces, it minimizes or eliminates challenges associated with single crystal diamond, such as the shape constraints and variability inherent in natural diamond. Finally, CVD diamond material can be manufactured with high aspect ratios (eg: 8mmX1mmX1mm), and CVD diamond can be cost-effectively mounted on dressing tools, extending life and improving dressing efficiency.


The natural qualities of vapor deposited diamond and the advanced technology in the manufacture of freestanding CVD diamond tools provide an excellent solution for many difficult-to-machine materials. With the success of CVD diamond in finishing tools, CVD diamond has been rapidly promoted and applied in the field of industrial material processing.
