Horizontal Precise Surface Grinding Machines MM71 series is suitable for grinding the planes surfaces and side faces of workppieces made of steel, cas

Features:

1) This series of machines is suitable for grinding the planes surfaces and side faces of workpieces made of steel, cast iron and nonferrous metal etc.

2) The longitudinal traveling of working table is hydraulic transmission, and the transverse moving of working table adopts the rolling linear motion guide with high precision and sensitivity.

3) Polytetrafluoroethylene soft strip is pasted on the guiding track of working table to decrease guiding track wastage and machine's energy consumption.

4) The movement of grinding head is manually operated but also equipped a quick elevating device for easy and efficient operation.

5) The grinding wheel head spindle bearing adopts the unitary sleeve bearing and the thrust bearing with high carrying capacity and slewing precision. The roughness is low and it's convenient to operate.
