Centerless grinding for shock absorbers is an application that presents some of the most daunting challenges for abrasive manufacturers. The range of requirements and priorities varies from product to product, calling for an equally wide range of solutions. Since, in most centerless grinding applications, more than one wheel is mounted on the spindle, extremely tight tolerances must be maintained in wheel geometry and density to ensure uniform wear patterns, even when each wheel in the set is different. CUMI has the expertise when it comes to centerless applications thanks to the advanced manufacturing process, premium abrasive grains, and specially designed vitrified, resin, and rubber bond systems to suit the application needs. Customized solutions are provided for every application and specific requirement. Be it through-feed, end-feed, or in-feed, CUMI wheels ensure that components are finished to stringent quality requirements.
