A force model was developed for crankshaft pin grinding to predict the forces generated during grinding. The force model developed builds on the authors' previously developed model, which predicted the out-of-roundness in crankshaft pin grinding. The model includes key grinding variables, such as the work removal parameter (WRP), system ...
A new approach for the precise grinding of crankshaft pin is presented. In which, noncircular following strategy is investigated based on the motion model consists of horizontal feeding axis, additional lifting axis for wheel frame, and the active rotary axis for workpiece. The straight line relationship of wheel center, pin center and grinding point is ensured by the synchronism between ...

TECHNICAL FIELD. This invention relates to crankshaft pin grinders and particularly to a belt grinder for crankshaft pins. BACKGROUND. It is known in the art relating to the manufacture of crankshafts to use a grinding wheel to finish grind the crank pins which are eccentrically mounted with respect to the crankshaft axis of rotation.
Nov 22, 2010· Grinding the crankshaft is a relatively straight-forward process. The crankshaft nose is placed into the head stock chuck and the crankshaft flange (in some cases the crankshaft seal surface) is secured in the tail stock chuck. At which point the main journals can be ground. The rod journals are...
