  Description of the grinding performance of high-speed grinding wheels.

  Grinding amount

  1. Increasing the feed rate can improve the grinding efficiency, but at the same time it will increase the surface roughness of the workpiece, accelerate the wear of the grinding wheel, and reduce the durability.

  2. Increasing the speed of the grinding wheel can improve the surface roughness of the workpiece, increase the metal removal rate and metal removal parameters, and improve the durability of the grinding wheel.

  Grinder

  1. The grinding machine has high precision, which can ensure that the workpiece processing requirements are met and the performance of the grinding wheel can be fully exerted.

  2. The grinding machine has high rigidity. Under the action of the grinding force, the reduced elasticity can inhibit the generation of self-excited vibration, which is beneficial to the performance of the grinding wheel.

  Conditioning

  1. In rough grinding, high grinding efficiency is mainly required. At this time, rough dressing is better than fine dressing.

  2. If the grinding is limited by the surface roughness of the workpiece, the fine dressing is better than the rough dressing, but the excessive fine dressing will reduce the metal removal rate and increase the risk of burns; at the same time, it is easy to cause vibration, but the grinding wheel The durability is reduced and the productivity is reduced.

  Workpiece nature

  1. Workpiece materials, the grinding performance of easy-to-grind materials and hard-to-grind materials are very different, and the durability of the grinding wheel will also be significantly different.

  2. Processing requirements, workpiece processing accuracy and roughness are different, and the characteristics of the grinding wheel are also different.

  The performance of the grinding wheel itself

  The selection of the parameters of the grinding wheel should be correctly matched with the grinding conditions and processing requirements.
