Surface grinding - Midrand

M7130G Series surface grinding machine with horizontal grinding wheel spindle and reciprocating table .
This series machine tools include Model No. M7130G/F It is a new product on the foundation of M7130G surface grinding machine improved, It is suitable to grinding the various part's surface in machinery industry. 
The grinding machine working table's lengthways moving and grind head's transverse moving is hydraulic transmission, the stepless velocity modulation; 
1.The machine tool bed adopts the heat symmetry design, and the heat-distortion is become a little; Using the oil returning to heat the bed slideway, the slideway straightness change is below 0.005㎜; 
2. The grind head perpendicular feed for the hand moves, and have the quick elevating mechanism, and it can lighten labour intensity, raises work efficiency; 
3. The partly electrical equipment carried out the new national standard, and increasing the electrical equipment interlock safety device, and it is very convenient to operate; 
4. Grinding head perpendicular feed slideway installs the boundary lubrication material of my factory originates straight line bearing, and feeding sensitivity is high; 
5. The machine tool motion is smooth and steady , the function is reliable and the noise low , the precision stable and it is convenient to operate.
