Automotive industry - Finishing solutions for piston parts

Engine pistons

The piston is the reciprocating part of the cylinder block of an automotive engine. WSS solutions and tools for aluminium alloy pistons rely on the practical application of a team of specialists who are committed to optimising and improving the tools to create a better standard of workmanship.

Piston ring machining

WSS CBN external grooving inserts provide close grooving of piston surfaces with excellent cutting control and a wide range of sizes to meet different machining requirements. They are the most cost effective choice for long and stable grooving.
