Abstract
Based on the principle analysis of two-axis linkage and cut point tracking crankshaft servo grinding technology, the principle of triaxial linkage and cut point tracking for crankshaft servo grinding is analyzed and researched on the technological advantages for the neck of crankshaft connecting rod and the spindle neck. Then the dynamic grinding model is established, and the high-precision liquid hydrostatic slide-way technology, high rigidity straight line drive technology and on-line measurement and error compensation technology are employed synthetically to solve the dynamic performance of moving parts for ultra-precision grinding and its influence on the machining accuracy successfully. The problem of using common corundum wheel to process the crankshaft neck and connecting rod efficiently and accurately is conquered.
