Rotary Dressing Disc The CNC dressing technique can be used in all fields of grinding production, especially for small and medium production lot sizes and for prototype applications. The profile of the grinding wheel is created by the CNC controlled process that moves the rotating form roll along the target contour. Form rolls are therefore not restricted to a specific workpiece but can be used flexibly.

Profile Rolls Profile rotary diamond dressers are used to form grinding wheels for many different kinds of mass production. Profile rolls transfer a defined shape to the grinding wheel rim, which is used to generate the workpiece profile. Usually the profile of the roll corresponds precisely to that of the workpiece but it can also be adapted to the specific grinding. Shorter dressing time and long tool life leads to high productivity and consistent process conditions. Many kinds of conventional grinding wheels, and in special cases super-hard grinding wheels, can be dressed with this dressing method.

Rotary Diamond Dressers Are Divided Into Profile And Form Rolls
depending on the type of abrasive layer profiling
Diamond Profile Dressing Rolls
* Profiling of the grinding wheel along the desired contour by moving the diamond dressing roller
* The profile of the grinding wheel is created by a CNC controlled process that moves the rotating form roll along the target contour
* Form rolls are not restricted to a specific workpiece but can be used flexibly
Diamond Form Dressing Rolls
* Profiling of the grinding wheel in only one operation using the plunge-cut dressing method
* Usually the profile of the roll corresponds precisely to that of the workpiece
* Extreme accuracy, even with highly complex profile contours
