This machine is mainly used for grinding of different kinds the straight-bladed cutters with different angles, which is mainly composed of six major parts, i. e., a body, a workbench, a sliding plate, a motor, a wheel head and electrical parts. The structures of various parts are compact; the appearance layout is beautiful and reasonable. The tracks have been precisely processed and the running bearing shaft is eccentrically designed and triangularly positioned, during the running, the bearings at the ends are downward to touch the track and the middle bearing is upward to touch the track, so high-precision transmission is enabled to achieve. The wheel head goes automatically in a stable and stable speed to play its unique advantages to ensure a uniform height and a uniform weight and etc. Being able to grinding four blades at the same time, it is suitable for different types of cutters in furniture, printing, textile and other industries and can also be used for skew opening processing of high-speed tool steel and it is the preferred equipment for related manufacturing enterprises.
