Geometric accuracy of grinder: It refers to the movement accuracy and mutual position accuracy of each part without bearing the load. It is impossible to make a machine tool absolutely accurate, and there are always more or less inevitable errors. This kind of error will be reflected to the w...... [Read More]

(1) With the increase of dressing speed ratio, the overall surface roughness of the workpiece increases, but the roundness of the workpiece decreases. (2) With the increase of dressing depth, the workpiece surface roughness and roundness decrease first and then increase. (3) With the increase ...... [Read More]

If rough machining and finish machining are carried out continuously on the machining center, the fixture should not only meet the requirements of large cutting force, high stiffness and large clamping force during rough machining, but also meet the requirements of high positioning accuracy an......
