Main Features
1.The machine has the characteristics of high cutting precision, strong rigidity and high efficiency. Suitable for grinding cylindrical and conical workpieces.
2.Machine workpiece, outer round grinding wheel, inner ring grinding wheel, oil pump and cooling pump are driven by independent motors.
3.The longitudinal movement of the machine table can be driven by hydraulic stepless speed change, or by handwheel, and the workbench is lubricated in the form of small hole throttling and unloading.
4.Each moving part of the machine tool has electrical, hydraulic and mechanical interlocking mechanisms, so the operation is safe and reliable.
