The taper products have the taper adjustable or use waterproof paper to pad the deciduous board of the machine tool guide wheel surface;
Check whether the guide wheel shaft of the machine tool is too loose. The standard is below, and the poor finish of machine tool grinding products may be caused by the following problems:
The center height of the product is too low (use equal-height gaskets or cylindrical pins, the standard is below);
The grinding area of the product is too short;
The vibration of the grinding wheel is too large (use the balance frame to adjust the static balance) The quality of the machine tool guide wheel is too poor (the surface of the good guide wheel is smooth after trimming, and the texture is uniform without pores);
Whether the machine tool has oil slick or has deteriorated;
The roundness of the product is not good, and the center height of the product is too low;
See if the machine grinding sound and sparks are normal;
Whether there is abnormal vibration when the machine tool is grinding;
Solution Please come to the standard M series of motor bed shaft accuracy. Because the longitudinal direction of the grinding wheel shaft is 0.02 mm, the axial direction is 2 mm, the hand is pushed hard and the rebound is strong, and the rotation accuracy is within 0.003 mm. Since the warp direction of the guide wheel shaft is 0.005 mm, the axial direction is within 0.008 mm, and the rotation accuracy is within 0.003 mm. In the case of the MG series, the longitudinal direction of the grinding wheel axis is 0.01 mm, and the axial direction is 2 mm. The hand is pushed hard to rebound and the rotation accuracy is within 0.003 mm. Except for hydrostatic floating shafts (MGT1050), since the guide wheel shaft is 0.005 mm in the longitudinal direction, the axial hand is pushed hard to rebound and the rotation accuracy is within 0.003 mm. The standard rough grinding product of the center height of the machine tool is generally the center of the grinding wheel shaft of the machine tool. The center height of the fine grinding product is the center height of the machine shaft plus 1/2 to 2/3 of the product center height. Since thin products are easily deformed, the height should be as high as possible (the product does not jump during grinding as the standard)
