The machine tool is mainly applicable for grinding allkinds of straight blade cutters with different angles, mainlycomposed of six major parts, i.e., a machine body, a worktable, asliding plate, motors, a grinding head and electriccomponents. The various parts are of compact structure,beautiful appearance and reasonable layout. The rail is preciselymachined, and eccentric design and triangular positioning methodare adopted for running bearing shaft, the bearing at two ends aredownward faced to contact the rail, and the middle bearing areupward faced to contact the rail and travels, so high-precisiontransmission can be achieved. The cutter travel for grinding headis automatic, stable with uniform speed, possessing its uniqueadvantage to ensure the uniform height and uniform weight of thecutters, and four blades can be simultaneously ground. It issuitable for a variety of different types of cutters in furniture,printing, textile and other industries, it can also be used foroblique opening processing of high-speed tool steel and etc, beinga preferred equipment of related manufacturingenterprises.
