M7140A,M7130A

Wheel Head Moving Surface Grinding Machine M7140A,M7130A

Main features:

1.Wheel Head moving, Horizontal spindle, suitable for heavy-duty cutting

2.Grind wheel head spindle frontend adopts shell bear bearing support, rear end adopts Roller bearing,

with high rigidity, specially for heavy-duty cutting.

3.Transmission: Worktable adopts one flat and one V guide ways, driven by hydraulic with smooth movement.

4.Grinding wheel adopts two setsof guide way, one is flat guide way for up/down moving.

5.Another set isswallow tail guide way for back-forward movements, with manual feeding or Auto-feeding

byhydraulic cylinder.

6.The M7130AL,M7140A,M7150A,M7163 series surface grinder adopts the cooler for hydraulic oil tank.
