POLISHING REPLACEMENT STONES KIT

Function and technical context

Polishing stones are the consumable abrasive elements of the finishing and grinding system used in the maintenance of onboard metal surfaces such as cylinders, ports and valve surfaces in outboard and outboard marine engines. This replacement kit (ref. CRA946331) allows you to completely renew the set of stones of a polisher without having to purchase the complete tool, reducing the maintenance cost of the nautical workshop. Excessive stone wear results in poor surface finish, inadequate frictional heat generation, and ultimately damage to treated surfaces requiring costly rework or component replacement.

When to replace this part?

The most common signs of polishing stone wear are the loss of abrasive capacity - the tool stops removing material uniformly - the appearance of irregular scratches on the treated surface and visible wear or fracture of the abrasive segments. It is recommended to inspect the condition of the stones after each session of intensive work and replace them preventively when they present a significant reduction in their dimension or when the finish obtained does not reach the required tolerance; In workshops with frequent use, it is advisable to check the game at each seasonal maintenance. Always having a spare kit in the workshop avoids unforeseen stops during critical interventions on marine engines.
