Detailed Description
The specific implementation manner of the utility model is as follows:
referring to fig. 1, a grinding plate 3 is adapted to a swing machine 1, the grinding plate 3 is mountable to an output shaft of the swing machine 1, and the grinding plate 3 includes a mounting portion 5 coupled to the output shaft and a working portion 7 connected to the mounting portion 5.
Referring to fig. 2, the working portion 7 includes a main body 8 and a polishing layer 9 provided on the main body 8. The body 8 has two faces facing away from each other and a side wall connecting the two faces. The main body 8 is at least partially provided with a polishing layer 9 for polishing a workpiece. If the sanding layer is provided on at least one of the two faces or on the side wall, it is of course also possible for both the faces and the side walls of the working part 7 facing away from each other to be provided with the sanding layer 9. The polishing layer 9 may be composed of diamond particles. Of course, the abrasive layer 9 may also be sandpaper.
The thickness of the working part 7 does not exceed 2.5 mm. Preferably, the working portion 7 has a thickness of 0.5mm to 1.3 mm. Preferably, at least one of the two faces is provided with a polishing layer 9, the thickness of the polishing layer 9 on each face is not more than 0.5mm, and the thickness of the body 8 is not more than 0.8 mm. Set up the layer of polishing in the main part of work portion to guarantee the thickness of work portion, make the abrasive disc can go deep into constrictive space, satisfy the work demand of polishing to the surface in constrictive space.
