Solutions to common problems of centerless grinding machines
products have adjustable taper or use waterproof paper to pad the deciduous plate on the guide wheel surface of the machine tool; Check whether the guide wheel shaft of the machine tool specified in 5.5.3 is too loose The standard is below,
the poor finish of machine tool grinding products may be the following problems: the center height of the product is a rare experimental equipment for testing the fatigue performance of springs, which is too low (it is padded with equal height gaskets or cylindrical pins, and 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) and the quality of the guide wheel of the machine tool is too poor (the surface of the good guide wheel is smooth after trimming, and the texture is uniform without fine holes,); Whether the cutting fluid of the machine tool is floating. The computer tensile testing machine produced by Jinan assaying meets the manufacturing standard of testing machine gb/t16491 ⑴ 996 "standard for electronic universal testing machine" or has deteriorated
the recent five gold tool torque testing equipment has ushered in a new opportunity. The roundness of the product is not good, and the center height of the product is too low; Check whether the grinding sound and sparks of the machine tool are normal; Whether there is abnormal vibration during grinding of machine tool; Solution please call
machine tool axis accuracy standard
m system example
the meridional factor of the grinding wheel axis is 0 02 mm, 2 mm in the axial direction, strong push back by hand, and the rotation accuracy is 0 Within 003 mm.
the meridional factor of guide wheel shaft is 0 005 mm, axial 0 Within 008mm, the rotation accuracy is 0 Within 003 mm.
mg system example
the meridional factor of the grinding wheel shaft is 0 01 mm, 2 mm in the axial direction, strong push back by hand, and the rotation accuracy is 0 Within 003 mm. Except for static pressure floating shaft (mgt1050)
the meridional factor of guide wheel shaft is 0 005 mm, the axial hand force pushes back the spring forcefully, and the rotation accuracy is 0 Within 003 mm.
standard for the center height of the workpiece processed by the machine tool
rough grinding products are generally centered on the center of the sand axle of the machine tool
fine grinding products. The center height of the product is the center height of the machine tool axle plus 1/2 to 2/3 of the center height of the product.
thin products should be as high as possible because they are prone to deformation (taking the product does not jump during grinding as the standard) (end)
