Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheels, in particular to a grinding wheel used for grinding the front angle part of a saw blade. Background Art

[0002] Grinding wheels are important cutting tools made of abrasives and used on grinding machines. The appropriateness of the choice of grinding wheels directly affects the grinding performance and processing accuracy of the grinding machine. Therefore, grinding wheels are an important factor in exerting the performance of the grinding machine. When determining the specifications of the grinding wheel, the main factors to be considered are the material and hardness of the workpiece, the grinding amount and precision requirements, the grinding method, the grinding wheel speed, the grinding contact area, and the intensity of the grinding method. There are many types of grinding wheels, and they have various shapes and sizes. Due to the different abrasives, binder materials, and manufacturing processes of the grinding wheels, various grinding wheels have different working performances. Each type of grinding wheel has a certain scope of application according to its own characteristics. Therefore, when grinding, it is necessary to select a suitable grinding wheel according to the specific situation, otherwise the processing accuracy, surface roughness, and production efficiency will be directly affected due to improper selection of grinding wheels.

[0003] See also Figure 1 and Figure 2 In order to grind the front angle portion 11 of the saw blade 10, the abrasive layer 21 of the grinding wheel 20 can only be designed to have a smaller ring width W, that is, the wall thickness of the abrasive layer 21 of the grinding wheel 20 is smaller. At this time, in order to ensure the grinding quality, the height X of the abrasive layer 21 of the grinding wheel 20 can only be appropriately shortened to ensure that the abrasive is not easy to break, which leads to a reduction in the service life of the grinding wheel.

[0004] Therefore, the applicant has found a solution to the above-mentioned problem through beneficial exploration and research, and the technical solution to be introduced below is produced in this context. Utility Model Content
