Description

Technical Field

[0001] The utility model belongs to the technical field of grinding wheels, and in particular relates to a heavy-load resistant rough grinding resin grinding wheel. Background Art

[0002] At present, a large number of high-speed heavy-duty grinding wheels are used in the steel, machinery, railway and other industries to grind steel billets, steel, rollers and railway track surfaces. The grinding wheels are almost all made of high-energy-consuming corundum or silicon carbide resin grinding wheels. Such grinding wheels have the following defects: 1. The consumption is large, the cost is high, and the environmental pollution is caused at the same time; 2. The grinding wheel is easy to burst due to structural design reasons, which makes it unsafe and has a short service life; 3. Although the existing metal bond superhard material grinding wheels have the characteristics of wear resistance, durability and ability to withstand heavy loads, they are difficult to remove chips when used, which not only reduces the durability of the grinding wheel, but also affects the service life of the grinding wheel, and it is also easy to burn the workpiece, making the workpiece become waste, and cannot meet the existing production requirements.

[0003] In order to solve the above problems, we propose a new heavy-load resistant rough grinding resin grinding wheel. Utility Model Content

[0012] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0013] The heavy-load resistant rough grinding resin grinding wheel provided by the utility model has a structural design that can not only ensure the overall structural strength of the grinding wheel and prevent the grinding wheel from bursting, but also ensure that during use, the grinding wheel itself and the cut workpiece are efficiently cooled, and at the same time, the debris generated by cutting can be discharged in time, thereby ensuring processing efficiency and extending the service life of the grinding wheel.
