Скачать или смотреть Outer diameter grinding of wheel hub bearings / cnc grinding machine in bearings production industry

Outer diameter grinding of wheel hub bearings has higher dressing accuracy that the dressing is one of the most critical operations within a grinding machine. This operation was carried out during parts loading and unloading, returns the grinding wheel profile to that required by the specification. Using cnc system can control this dressing operation can be carried out in a number of ways. for example, with the required profile for the grinding wheel programmed within the numerical controller, dressing unit can be carried out by the full-profile rollers, linear diamond dressers or single-point diamond dressers, depending on the configuration of the particular part.

The speed of grinding is controlled by the high-stablish dynamic hydraulic spindle and depends on the size and shape of the workpiece and the type of grinding operation. we are looking to grinding parts at higher rigidity grinding and stability to satisfy the higher material removal rates, better surface roughness and lower wheel wear, which reduce overall grinding costs.with these general developments in grinding technology has been the use of new types of abrasive materials for the grinding wheel. This has contributed to higher grinding accuracy.

For cross slides on which the grinding wheel is moved under numerical control are hydrostatically supported. The cross slides, equipped with ball screw and servo motor, have a feed rate of high speed (cross) and a feed resolution of 0.2µm.

The grinding process is normally under numerical control. In accordance with the modular concept the grinding machine can be used in conjunction with a number of controllers including its own cnc system which comes with a sophisticated graphic controller interface. The control system not only allows the setting up of the parameters required but also, through information gained from the in-process measurement system, adaptive control of the grinding process is possible.
