As the name suggests, precision grinder requires high precision. Where is the high precision? First of all, the stability of the whole machine body, the material of the casting itself, the structure of the steel column and the stability of the foundation, coupled with the firmness of the whole machine body, the casting should focus on the stability of the machine. Then, the process of making the whole machine body, the accuracy comes from the spading, the accuracy of the track and the balance of the level. The verticality of the column and the level of the table should form an absolute 90 degree, which can not be false, Combined with all the above production, basically a grinder will be stable on the basis. Only with a stable machine tool can we talk about the accuracy. According to the strict test data, strictly control, equipped with good accessories, high-precision electronic ruler and non deformable disk, the ground workpieces will not deform. In case of workpieces with large deformation coefficient, water mill must be equipped, In this way, the absolute accuracy of workpiece testing is high in the process of overall grinding!
