Detailed Product Description
CNC8312 Numerical Control High Speed Camshaft Grinder
MAIN FEATURES:
1.Equipped with the SIEMENS computer control system (SINUMERIK 840C)and AC servo driving system(611D)
2.the main shaft system of grinding wheel adopts dynamic-static pressure bearing;high accurracy static pressure mainshaft unit with constant temperature oil tank. The bear is of high stiffness
3.CBN wheel is applied.The maximum grinding wheel linear speed is 120m/s.The speed of main grinding wheel motor is controlled by frequency converting speed regulator,which makes the line speed constant with the wheel wear and tear.
4.The wheel is equipped with dynamic balancer(SBS USA)to eliminate empty run and with anticollision device.
5.Diamond roller mechanism,which is of the function of wheel compensating and automatic correcting,is used to correct the wheel wear
6.No cam is used,so the time and expense are saved,and it is simple and quick for different workpiece.And accuracy is greatly increased because of non-cam manufacture error and decrease of mechanical contour error.
7.Enclosed structure and nice appearance.
