Grinding machine

　　The utility model relates to the electrode processing equipment, in particular a grinding machine for grinding the clamping end of the manual welding electrode. The utility model is proposed to solve the problem that the existing parts and components of the lifting machine are large and the adjustment is inconvenient, and the maintenance of the platform is easy and the maintenance of the platform is easy. The utility model set the column, the screw as a whole, with two groups of upper and lower rotation to adjust the distance between the two platforms to achieve the upper and lower wire wheel between the lifting control. In addition, the utility model uses the vertical planetary cycloid reducer to replace the existing equipment in the worm gear drive slowdown mechanism to improve the transmission efficiency
