high precision hydraulic Wheel Head Moving Surface Grinding Machine for metal
machining workshop for surface grinder.
The accuracy of this machine is 0.005mm and it can meet the routine machining job requirement.
The worktable longitudinal movement is driven by the vane pump, so that to make the movement stable and fluently with low noise.
The wheel head adopts the bearing bush structure, so that to handle the heavy duty machining job.
The machine gets the hydraulic auto feed and manual feed in cross feed unit, which is very convenient for operation. The wheel head vertical movement is controlled manually, it also equips with the rapid elevating unit to reduce the labor intensity and improve the working efficiency
Every month, we will export almost 500 sets surface grinders in the worldwide. We think we can give you the most comprehensive support not only service but also techniques. Because we are a know-how machinery expert.
