[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] like Figure 1 A grinding wheel with a central hole for exhaust as shown in FIG. 2 includes an internal base ring structure 100 and an external abrasive ring structure 200. The base ring structure 100 is tightly attached to the inside of the abrasive ring structure 200 to form a complete diamond grinding wheel.

[0026] A plurality of first exhaust channels 110 are radially arranged in the base ring structure 100 with the grinding wheel axis 1 as the center, and the first exhaust channels 110 are evenly distributed with equal distances. The radiation angle of the first exhaust channels 110 is 20°.

[0027] Focus on combination Figure 2 The first exhaust passage 110 is provided with a connection and installation hole 111 for connecting with the exhaust equipment management on the inner surface facing the base ring structure 100. The connection and installation hole 111 can be connected to the exhaust device (not shown in the figure) of the compressed air.

[0028] A plurality of second exhaust channels 210 are radially arranged in the abrasive ring structure 200 with respect to the grinding wheel axis 1, and the second exhaust channels 210 are evenly distributed at equal distances. The radiation angle of the second exhaust channels is 20°.

[0029] Focus on combination Figure 1 The first exhaust channel 110 is connected to the corresponding second exhaust channel 210 , and the average pore size of the first exhaust channel 110 is greater than the average pore size of the second exhaust channel 210 .

[0030] Specifically, the aperture of the first exhaust passage 110 on a side close to the connection installation hole 111 is larger than the aperture of the first exhaust passage 110 on a side away from the connection installation hole 111 .

[0031] The aperture of the second exhaust channel 210 on the side close to the base ring structure 100 is larger than the aperture of the second exhaust channel 210 on the side away from the base ring structure 100 .

[0032] The diamond abrasive layer is a material that is difficult to process. It can be processed by using an electroplated diamond drill bit. After the holes are drilled on the abrasive surface, it can be processed by using a drill bit for processing the base material.

[0033] The exhaust channel extends from the inner hole of the grinding wheel base to the outside of the abrasive layer, running through the entire grinding wheel. A machine tool with a matching spindle ventilation is used, and an exhaust device that can be connected to compressed air is arranged on the grinding wheel mounting shaft. After docking with the connecting mounting hole 111 of the grinding wheel, the grinding wheel abrasive can be exhausted from the inside to the outside, blowing away the dust generated during processing and preventing the workpiece from being scratched.
