The cylindrical grinder is mainly used for precision grinding of end faces, outer circles, and conical surfaces of batch shaft parts, and is the main equipment in industries such as automotive engines. It is also suitable for the processing of shaft parts with small batch sizes and high precision requirements in aerospace and general precision machining workshops; Used for upper roller processing in textile spinning industry, including coarse and fine yarn machines, drawing machines, combing machines, and carding machines; Used for the production and manufacturing of office communication equipment industry, fax machines, copiers, printers, engraving machines and other rubber roller processing; Suitable for automatic conveyor rollers and plastic processing in the printing, food, and pharmaceutical industries.
Factors affecting the accuracy of cylindrical grinding machines:
1. The influence of the height of the grinding head, headstock, and tailstock on the dimensional accuracy of the workpiece. The height error of the grinding head, headstock, and tailstock will cause the centerline of the headstock and tailstock to deviate from the axis of the grinding wheel spindle in space, resulting in a hyperbolic surface on the surface of the workpiece being ground.
2. The influence of the parallelism error of the grinding head spindle axis in the horizontal plane on the dimensional accuracy of the workpiece caused by the centerline connecting the headstock and tailstock. When this error occurs, the shape of the workpiece ground by the external cylindrical grinder will be a cone, that is, the grinding wheel will grind at an angle, and the surface will have spiral grinding patterns.
3. The influence of perpendicularity error of grinding head movement relative to machine tool guide rail on machining accuracy. The result of this error is a deviation of the spindle axis from the centerline of the headstock and tailstock. When grinding the shoulder end face, it will cause a vertical deviation between the shoulder end face and the workpiece axis. When grinding the outer circle, it will affect the surface roughness and produce spiral grinding patterns.
