What are the main reasons for the grinding performance of heavy-duty grinding wheels?

   I. Grinding machine:

  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 utilized.

  2. The grinder has high rigidity. Under the action of grinding force, the elasticity is reduced. At the same time, self-excited vibration can be suppressed, which is conducive to maintaining and exerting the grinding performance of the grinding wheel.

   II. Grinding amount:

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

  2. Feed rate and feed rate. 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.

   III. Dressing conditions:

  1. For grinding processes where the workpiece surface roughness is the limiting condition, fine dressing is better than rough dressing, but if the dressing is too fine, the metal removal rate will decrease, and there is a risk of burning; at the same time, it is easy to cause vibration, which reduces the durability of the grinding wheel and reduces productivity.

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

   IV. Workpiece properties:

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

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

   V. Cooling conditions:

   The appropriate combination of liquid supply method, pressure and flow rate, and various types of grinding fluids selected during the grinding process will greatly improve the grinding performance of the grinding wheel, and the grinding effect will be doubled.

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