1.磨床的用途及运动 生产轴承用的磨床一般都是轴承专用磨床,其工作范围很广,可磨削各种形状表面,如轴承套圈的外径、内径、端面和沟道等等。轴承专用磨床的种类虽较多,但却有共同的基本运动形式,如:砂轮的旋转运动、工件旋转运动、纵向进给运动、横向进给运动等。有些磨床还有头架摇摆运动和工作台振荡运动。 1. Grinder use and sports production Grinding bearings are generally bearing special grinder, its wide range of work, can grind a variety of shapes and surfaces, such as the bearing ring diameter, diameter, face and trench and so on. Although there are many types of bearing special grinding machines, they have common basic forms of motion, such as the rotating motion of the grinding wheel, the rotation of the workpiece, the longitudinal feed motion, and the transverse feed motion. Some grinders also have headstock rocking and table oscillation.
