Jan 01, 2015· Path controlled grinding process has been used in automotive powertrain industry. The grinding conditions are periodically changing between grinding wheel and crankpin due to the existence of the eccentricity of crankpin and constant rotation speed of crankshaft. ... Crankpins are generally subjected to high thermal and cyclic loads when ...
Inspection of Crankpin is in Process . II) Polishing or undersize of journals and crankpin: On the basis of surface geometry reports available decision is taken in regard to polishing or grinding of crankpin and main journal.In the event of minor bearing line marks, pitting or rough surface it is recommended that these defects are removed only by process of polishing of crankpin and main journal.
The distinctive deformation deteriorates the coaxiality of all the main journals and thus the grinding precision of crankpins in non-circular grinding. ... grinding process control problems that ...
