Piston Engine Valve Stem

The piston engine valve stem is a rod-shaped object that connects the cam and the valve, which are installed on the engine valve. It is mainly used to transmit the cam trajectory. During normal engine operation, the piston engine valve stem needs to withstand extreme working environment such as high frequency , high temperature and high pressure.

The piston engine valve stem is usually made of high-quality alloy steel such as 15Cr, 20Cr, and 45Cr. These alloy steels have excellent performance in extreme working environment due to the high hardness and excellent wear resistance. The materials of piston engine valve stem include 5Cr21MnNi4N, 2Cr21Ni12N, 4Cr14Ni14W2Mo, 4Cr9Si2, 4Cr10Si2MO, and 8Cr20Si2Ni.

Feature Of CBN Disc For Cutting Piston Engine Valves Stem

CBN has high hardness, which means stronger and sharper cutting ability.

CBN has high wear resistance, which means it is more difficult to wear than the traditional abrasives. The ability to maintain the shape of abrasive particles is one of the main features of CBN. CBN has high compressive strength, which means it can maintain particle integrity and is not easily broken when working under harsh condition. CBN has good thermal conductivity and can achieve cold cutting.

When grinding and cutting iron materials, there will be no sticking. It is an ideal cutting tool for metal material that are sensitive to grinding temperature, such as quenched steel, high vanadium high-speed steel, and etc.
