The connecting rod journals are also called as crank pins or rod bearing journals. It will be easily broken off because the stress here is concentrated. So the eccentricity, parallelism, distortion and R angle of connecting rod should be carefully controlled during connecting rod journals machining.
Nazhen will choose different CNC turning lathe and CNC grinding machine. Before machining, the crankshaft will be placed on the auxiliary tool produced by ourselves to make sure that the crankshaft is fixed on it. Then the machining efficiency can be improved and the machining precision can be ensured. After finishing the machining, we will carry out quality testing by adopting deflection instrument, coordinate measuring machine, altimeter and profiler to ensure that the crankshaft machining is in line with the blueprint.
