• This machine is a major grinder professional advantages of manufacturing units in the the M130H， M1420H type cylindrical grinder on the basis of draw to improve improve Heavy Duty Grinder, with high cutting precision, high rigidity and high efficiency. Suitable for grinding cylindrical and conical workpiece.
• The workpiece of machine ，cylindrical grinding wheel, the inner circle of the grinding wheel, oil pump and cooling pump by an independent motor drive.
•The longitudinal movement of the machine table by the hydraulic continuously variable transmission can also be hand-wheel drive, table lubrication Orifice Compensated unloading form.
• Grinding wheel frame transverse feeding fine tuning can be made by the hydraulic feed and fast and automatic cycle, two feed hand wheel is also available to achieve the thickness.
• Grinding wheel rack main shaft diameters, motor power increase, grinding wheel rack oil pool temperature rise is small, high grinding rate.
• Machine moving parts with electrical, hydraulic and
