Company GSP – High Tech Saws, s.r.o. produces HSS circular saw blades for cutting piston rings.
The saw blades are produced from HSS steel grade M35 and M42. The PVD coating is possible.
The piston ring is an expandable and adjustable metal split ring used to provide a spring-loaded seal between the piston and the cylinder wall (against the cylinder wall). This metal springy split piston ring, usually one of a series, fits around a piston (into a groove on the outer diameter of a piston) and seals the gap between the piston and the cylinder wall to maintain a tight fit.
The main function of piston ring is to ensure a tight fit (seal the combustion chambre) in the engine cylinders for heat transfering from the piston (conduct heat from the piston) to the cylinder wall and for cylinder-wall lubrication (returns oil to the crankcase).
The piston rings are usually made of cast iron which retains the integrity of its original shape under dynamic forces an heat. Piston ring configuration and size depends on cylinder material and design of engine.
