The working principle of the diamond rotary dresser

By installing the diamond rotary dresser on the dressing device of the grinder. Diamond rolls dress ordinary ceramic grinding wheels or CBN grinding wheels. The grinding wheels are trimmed and shaped before grinding the parts, thereby copying the contour, accuracy, and size of the diamond rollers to the surface of the processed parts through the grinding wheels.

Application of diamond rotary dresser

Gears, bearings, aerospace, weapons manufacturing, auto parts, air conditioning compressors, tools, measuring tools and other industries

Processing object

Superhard ceramic abrasives, superhard resin abrasives, ordinary ceramic abrasives, etc.


High dimensional accuracy, good shape retention and long life.

Main types of diamond rotary dresser

Forming diamond  rollers:single-axis feed dressing

Single-axis rotary diamond dressers are used for grinding wheel shaping and are used in the series production of many different types of grinding wheels. Shorter dressing time, longer life, high productivity and consistent process conditions. A variety of general grinding wheels and some special super-hard grinding wheels can be dressed with this dressing method. CD dressing (continuous dressing) is commonly used for dressing grinding wheels used for machining hardened workpieces as well as high-temperature alloy fine profiles.

Diamond dressing Disk for flexible dressing

Dressing CNC dressing technology can be used in all areas of grinding production, especially small and medium-volume production and shaping applications. The flexibility of CNC control allows easy changes to the production process. Compared to single-axis insert trimming, CNC rotary trimmers have a lower cost per piece. Various types of grinding wheels can be dressed. CNC dressing discs with natural or CVD diamonds are used for dressing general grinding wheels. Self-sharpening rotary dressers are used to dress superhard grinding wheels. Precise optimization of dressing tools and spindle systems enables optimal runout tolerances and optimal dressing results for precision dressing applications.

Diamond rotary dressers for Profile Grinding

Since gear grinding is one of the final operations in gear production, rotary diamond dressers must combine long life with correctly contoured grinding wheels to produce high-precision geometries and the highest quality surface finish.

Dressers for Worm Gear Grinding

The production method of gear grinding is one of the most efficient processes for long-term production runs. Due to its extremely powerful dressing process, long-life electroplated gear dressers are used for this process. Innovation and continuous development of gear dressing machine manufacturing processes guarantee process-optimized dressing solutions for all machine systems.

    How to Grind Precision Ceramic Materails?

    In the process of ceramic processing, how to improve grinding efficiency, reduce surface roughness, and avoid the thermal impact generated during the grinding process are the main challenges. These challenges arise primarily from the hard and brittle nature of ceramic materials. Therefore, it is necessary to choose a grinding method with high grinding force and low grinding heat.Moresuperhard recommends using ceramic diamond grinding wheels as the main grinding tool to grind ceramic materials. Ceramic diamond grinding wheels have the characteristics of high grinding force, low grinding heat, and long service life, which can meet the needs of long-term and efficient grinding of ceramic materials.
