Cutting discs and grinding wheels are not exactly the same.
Both cutting discs and grinding wheels belong to the category of abrasives, but their main uses and characteristics are different. Cutting discs are mainly used for cutting operations. They are usually thinner and designed to be parallel. They are mainly used for cutting ordinary steel, stainless steel metal and non-metallic materials. Cutting discs are usually made of abrasives and binder resins, etc., and have the characteristics of high tensile, impact and bending strength. According to different materials, cutting discs can be divided into fiber resin cutting discs and diamond cutting discs. Fiber resin cutting discs use resin as a binder, combined with glass fiber mesh and a variety of materials, and are suitable for cutting hard materials such as alloy steel and stainless steel. Diamond cutting discs are mainly used for cutting hard and brittle materials, such as stone, concrete, etc., which contain diamonds. As the hardest substance at present, they can effectively cut the processed objects.
Grinding wheel discs are a wider category of abrasives, which are not only used for cutting, but also for grinding operations. The thickness of the grinding wheel disc can be adjusted as needed. Thinner grinding wheel discs are mainly used for cutting, while thicker ones are mainly used for grinding. Grinding wheel is a porous body made by adding binder to abrasive, pressing, drying and baking. It is one of the most important grinding tools in grinding. The characteristics of grinding wheel are mainly determined by factors such as abrasive, strength, binder, hardness, structure, shape and size, which have an important impact on the processing quality, productivity and economy of grinding.
In summary, although both cutting discs and grinding wheels belong to the category of grinding wheels, cutting discs are mainly focused on cutting operations, while grinding wheels have a wider range of applications, including cutting and grinding operations.
