Dressing solution for diamond peripheral grinding wheel

The necessity for wheel dressing

Grinding wheel dressing plays a vital role in high-speed and high-efficiency grinding, precision ultra-precision grinding, and form grinding. In the grinding process, the interaction between the grinding wheel and the workpiece surface is the main reason, and the grinding wheel gradually becomes dull as the grinding progresses, which is difficult to grind effectively. In order to ensure the grinding quality and precision, it is necessary to dress the grinding wheel regularly.

Grinding wheel dressing is mainly divided into two aspects: dressing and sharpening. dressing refers to the operation of processing the contour and shape of the grinding wheel, compensating for the shape loss caused by the grinding wheel in use, and processing it into a specified shape suitable for the shape of the workpiece. Sharpening refers to the adjustment of the surface of the grinding wheel to expose new abrasives and sharp points to form a cutting edge on the dulled abrasive grains.

Difficulties in Dressing Diamond Grinding Wheels

On the one hand, the superhard abrasive has extremely high mechanical strength and is extremely difficult to break. Moreover, the abrasive grains are embedded in the binder to form a dense structure of soft and hard combination. It is difficult to use the traditional dressing method to mix the binder and the grinding wheel like a normal grinding wheel. The grains are repaired at the same time. Therefore, the shaping efficiency is low, and the shaping is difficult.

On the other hand, because the superhard abrasive has high surface binding energy, it is not easy to form a high-strength bond with the binder. Therefore, the abrasive grains are not easy to be partially broken and repaired by the abrasive grains during the dressing process. It is difficult to achieve very precise dressing accuracy in the dressing result of the grinding wheel.
