With the “More Super Hard” PCBN tools, the automobile sleeve has better precision after processing, and controls deformation when cylinder block under pressure. Thus, the wear rate between cylinder block and cylinder sleeve is reduced very much, it improves engine’s efficiency, reduces fuel consumption and lower the engine’s noise.
