Grinding pistons and liners requires controlled material removal and excellent wheel stability to achieve the required dimensions and surface finish. CUMI provides application-specific grinding wheel solutions based on the component material, grinding operation, and machine requirements.
Our centerless grinding solutions are suitable for:
| Application | Material | Grinding Operation |
|---|---|---|
| Piston Rings | Grey Cast Iron | Rough & Finish Grinding |
| Piston Rings | SG Iron | Rough & Finish Grinding |
| Cylinder Liners | Grey Cast Iron | Rough Grinding |
| Cylinder Liners | SG Iron | Rough Grinding |
CUMI grinding wheels are manufactured with carefully selected abrasive grains and bond systems to support consistent grinding performance. The right wheel specification helps achieve:
CUMI wheels can be selected according to the centerless grinding process and component geometry.
Through-feed grinding is suitable for continuous grinding of cylindrical components and high-volume production.
In-feed grinding is used for components with steps, shoulders, grooves, or different diameters.
End-feed grinding is suitable for tapered components and applications where a specific section of the component needs to be ground.
The selection of a centerless grinding wheel depends on the workpiece material, grinding operation, required surface finish, dimensional tolerance, machine speed, and production requirements.
CUMI provides application-specific wheel specifications to help manufacturers achieve the desired grinding performance for piston and liner applications.
With expertise in abrasive technology and industrial grinding applications, CUMI develops grinding solutions for demanding manufacturing environments. Our application-focused approach helps manufacturers select the appropriate abrasive and bond system for their specific grinding requirements.
