High temperatures, exhaust gases as well as mechanical stresses and other negative factors acting on piston rings during their normal work requires the use of precise manufacturing solutions during piston rings production. Un­doubtedly grinding is the key process here.

ANDRE offers a number of solutions for piston rings producers. Thanks to many years of experience, we can offer high performance abrasive tools that achieve the required geometry parameters and desired surface quality.
