Machining of the сrankshaft crankpins

The machining and grinding of crankshaft crankpins without engine dismantling are performed by our specialists.

Machining and grinding operations are made to achieve the required size and the normal firmness level in accordance with the technical terms of crankshaft manufacturing. The available equipment enables us to machine crankpins of the diameter from 100 to 400 mm. The accuracy of the machining reaches 0,01 mm. The smoothness of the surface corresponds to the 9th class of roughness according to GOST 2789 (RA = 0.20 μm, RZ = 1.6 μm).
