● Double-ended Grinding Solution

Differential gasket requires medium grinding and quenching, followed by fine grinding with 580B (Note: According to the requirements of the host factory, it is divided into before and after quenching).

Core Objectives:
Precisely control the final thickness: Achieve the precise dimensional tolerance required by the drawings (usually micron level).
Ensure high parallelism: The parallelism between the two ground surfaces is crucial and directly affects the sealing performance.
Obtain good surface quality: The surface roughness must meet the requirements to avoid burns, scratches, and other defects.
High-efficiency production: Improve grinding efficiency and reduce costs while ensuring quality.
