usage and structural performance
this machine is widely used in aerospace,military and auto industry and for machining die,precise measuring implement,hardware,electric component,castings,nonferrous material and specially for machining precise spare parts in bulk.
machine is made strictly upon on nation's standard, cross slide-move structure, auto lubrication and stable performance with high accuracy;
Longitudinal traverse of working table is hydraulically driven with stepless shifting and vertical feeding and cross traverse are controlled by servo drive and electronic impulse with 2-axis CNC system to perform autocycle grinding and also concave-convex grinding can be performed by progamming.Grinding head is equipped with functions of crashproof and off ground auto-shut down;
The bed of machine and cross slide are equipped with unique patent design-tow "V" and two hard guideway contacting slide in order to making machine good guidance quality and strong loading capacity;
high-precise angular contact bearing is adopted for the shaft of grinding wheel that results in high machining accuracy and working efficience;
easy use, space-saving, energy-saving,cost performance and popular market.
