The grinding wheel, code 100100, is a precision tool used in maintenance and reconditioning processes associated with MAN L21/31 engine components. Designed for accurate material removal and surface finishing, it enables the restoration of critical parts such as valve seats, shafts, or sealing surfaces to their required tolerances and surface quality. Manufactured from high-performance abrasive materials bonded for durability and consistent cutting action, the grinding wheel delivers reliable performance under controlled machining conditions. Its role in achieving precise geometries and smooth finishes is essential for ensuring proper component function, extending service life, and maintaining the overall performance of the engine.
