[0002] Grinding wheels, also known as bonded abrasives, are made by bonding ordinary abrasives into a specific shape (mostly circular with a central through-hole) with a certain strength. They are generally composed of abrasive, bond, and pores, which are often referred to as the three elements of a bonded abrasive. Common types of bonded abrasives include ceramic (bond) grinding wheels, resin (bond) grinding wheels, and rubber (bond) grinding wheels. Grinding wheels are the most widely used and widely used abrasive tools. Rotating at high speed, they can perform rough, semi-finish, and fine grinding on the outer and inner circumferences, flat surfaces, and various shaped surfaces of metal or non-metal workpieces, as well as grooving and cutting.

[0003] When the existing grinding wheel is used to grind the slider, the grinding wheel is driven by the main shaft of the machine tool to rotate at high speed during processing, and reciprocates under the drive of the main shaft to complete the grinding of the slider groove. The grinding wheel is rotating at high speed. If the main shaft on which the grinding wheel is installed protrudes from the bottom surface of the grinding wheel or the bottom surface of the grinding wheel protrudes, it is easy to cause hidden dangers of collision and excessive grinding of the inner cavity of the slider during the process of processing and dressing the grinding wheel of the slider, thereby reducing the processing qualification rate and increasing production costs.

If the main shaft on which the grinding wheel is installed protrudes from the bottom surface of the grinding wheel or the bottom surface of the grinding wheel protrudes, it is easy to cause hidden dangers of collision and excessive grinding of the inner cavity of the slider during the process of processing and trimming the slider grinding wheel, thereby reducing the processing qualification rate and increasing production costs. Therefore, it is necessary to provide an anti-interference slider processing grinding wheel to solve the above technical problems.

[0006] Furthermore, the grinding portion of the slider is annular, and the machining tolerance is controlled within ±0.002mm.

[0007] Furthermore, the connection between the slider grinding portion and the grinding wheel is designed with an arc transition chamfer.

[0008] Furthermore, the side wall of the grinding portion of the slider is arranged with an arc chamfer.

[0009] Furthermore, the dimensional tolerance range of the grinding wheel is 0.002-0.004 mm.
