Rubber grinding

Principle of cylindrical grinding of elastomers

Cylindrical grinding is a finishing process that uses an abrasive wheel to smooth the external surface of a cylindrical rubber part. This process is commonly used to improve the dimensional precision and surface quality of rubber parts.

Before grinding, several steps are necessary:

Preparation of the rubber
Preparation of the inserts for bonding
Elastomer overmolding on the inserts

Semi-automatic grinding process

Advantages of cylindrical grinding of elastomers:



Improved dimensional precision: Grinding enables very precise dimensions to be obtained in terms of diameter and concentricity, which is essential for applications where tight tolerances are required.

Surface quality: The process significantly improves the roughness of the elastomer part, reducing imperfections and irregularities. A smooth surface is often required for roller applications with thermal printing, ticket distribution, … where uniform contact with other surfaces is crucial.
