Bearing ring face grinding method

Ring width is not only one of bearing installation datum, and grinding main technological datum of face grinding of each process is the first step of ferrule grinding processing. The main technical requirements: B, ( C。 ) One by one single width values: delta a ( △c。 ) One by one single width deviation; Va. ( Vc。 ) - A single width changes; The surface quality, etc. Ring width of the vertical surface grinding and double face grinding grinding points two cases. End of the vertical spindle surface grinding machine grinding bearing schematic diagram. Using this kind of small and medium sized ring end face grinding machine grinding, generally fall into two work steps: grinding the benchmark side first, after grinding the benchmark. Purpose is to ensure the accuracy of raceway position relative to the benchmark. Vertical plane grinding is relying on the grinding wheel face. Grinding force is small, most of the abrasive grain is below the line contact has a bad effect of the cutting force grinding condition. Therefore, even if each particle has a sharp edge, grinding efficiency is still very low, so as to grind not started, a so-called 'false Tun' phenomenon. Practice as you can see, the vertical height of grinding wheel in the part of the main function is the cutting depth on the outer circle around and close to the peripheral working face. That is to say, only near the perimeter of the grinding wheel on vertical grinding wheel working face end face grinding grain on the main cutting effect, and inside the perimeter of the grinding wheel face friction effect only on the parts. That, in addition to the above phenomenon of 'false Tun, also increased the calorific value and hinder the cooling fluid into the cutting area, cause burns on the surface of the work. The friction surface is also peeling off the free state of sand is not easy to discharge, and scratch good smooth surface
