This series of machine tools is a two-axis linkage CNC high-precision CNC cylindrical grinder, using SIMENS, FANUC or other numerical control systems. The movement of the worktable and the wheel carrier is completed by the AC servo motors on the Z axis and X axis to drive the ball screw. X, Z axis linkage realizes linear and circular interpolation, and completes the grinding of inclined surface and circular arc. Through reasonable programming, the machine can complete the grinding of single or combined surfaces such as cylindrical, conical, and shoulders of various small and medium-sized parts. The grinding wheel can be shaped and trimmed to achieve the shape grinding. In addition to the precision grinding of the outer cylindrical surface of traditional industries such as automobiles, motorcycles, compressors, automotive gearboxes, oil pump nozzles, and valve stems, the product is also suitable for rubber rollers such as stereo printing, ceramics, Precision grinding of outer cylindrical surfaces in emerging industries such as semiconductors.
