First, reduce the superfine grinding surface when the vibration, good surface shape and precision surface texture to reduce vibration, grinding super machine must have a good anti-vibration, bed and other important structural components with vibration absorption, super Precision grinding machine 6202 outside the raceway commonly used 60,000 spindle, grinding speed 60m / s or more, the domestic generally much lower, mainly by the spindle and the spindle speed, Main bearing performance limitations. In the high-speed grinding, the grinding force is small, the grinding metamorphic layer is thin, not easy to burn, but also can improve the machining precision and the efficiency, has the very big influence to the low noise ball bearing; Analyzes the deep groove ball bearings development and the damage reason development of
The higher the stiffness, the less the grinding speed is, the less the vibration of the grinding system. The higher the rigidity, the higher the rigidity of the spindle bearing is, and the higher the stiffness is, the higher the stiffness is. Random dynamic balancing technology to improve the vibration of the grinding spindle. Foreign grinding head vibration speed (such as Gamfior) is about one-tenth of the general domestic spindle; improve the grinding wheel Whetstone cutting performance and repair quality is essential. The main problem of grinding wheel Whetstone in China is the poor uniformity of the structure, seriously affecting the low noise ball bearing grinding super-processing quality; full cooling, improve the filtering accuracy; to improve the precision feed system resolution, reduce feed inertia; Process parameters and processing processes can not be ignored factors, the grinding residual to be small, form-bit tolerance strictly, small and medium-sized ball bearing outer diameter should not be super-fine grinding, coarse grinding ultra-should not be separated to ensure good surface quality.
