Grinding Wheels Manufacturer
Grinding wheels are wheels that are manufactured industrially from binders and hard, grained abrasive material. They usually have a hole in the middle. This hole is used for mounting on the grinding machine. Peripheral speeds can be up to 300 m/s. They are used for the machining (chip removal) of glass, wood and metal. Of course, other materials are also possible. This depends on the type of grinding wheel.
How do grinding wheels work and what exactly are they used for?
Depending on the field of application, grinding wheels are manufactured differently. In principle, they consist of three components: the pores, the bond and the abrasive grain. The abrasive can be pumice, garnet, natural diamond, emery, quartz or corundum. Mostly, however, grain materials are used which are produced synthetically. These are easier to adjust in their properties (manufacturing process). These include synthetic diamond, cubic boron nitride, silicon carbide and corundum. The grinding materials with the highest degrees of hardness are cubic boron nitride and diamond. Conventional materials are silicon carbide and corundum.
The main bonds used are galvanic, metallic sintered, synthetic resin bonds and ceramic bonds. However, if a high surface quality is required, polyurethane and rubber bonds are used. Of course, abrasives can also contain additives and fillers. These are required either for the manufacturing process itself or for changing the application properties of the grinding wheels. Synthetic resin bonds can therefore contain supporting grains. These provide higher viscosity, heat resistance and strength. Solid lubricants such as pyrite and graphite reduce the temperatures that occur during grinding.
Areas of application:
Depending on the desired result, a distinction is made between camshaft grinding, cylindrical grinding, ball grinding or flat grinding. If accuracy is important, a choice is made between rough grinding, medium grinding, finish grinding and pre-grinding. When it comes to the meshing geometry, cut-off or deep grinding are required. The grain size determines whether fine or coarse grinding is possible. With some grit sizes and materials, better accuracies than 2.5 micrometers can be achieved. Grinding discs are robust metal supports which are mounted on concrete grinders. These "grinding wheels" are suitable for the highest demands. Cutting wheels cut or cut materials.
What are the requirements for good manufacturers?
First of all, the quality of the products must be guaranteed by selecting the appropriate suppliers. The abrasives must be suitable for the respective application. Grinding tools are often used as polishing tools and are equipped accordingly.
Diamond grinding wheels have the necessary degree of hardness, which of course must also be guaranteed by the manufacturer. In addition, a reliable manufacturer requires accuracy, professionalism and customer-specific production. Especially in today's fast-moving world, it is essential to be able to manufacture according to customer requirements. Because the requirements are constantly changing and special requests must be realizable. One of the quality requirements for the manufacturer is a good longevity of the products. On-site advice, special tools and many years of experience or creativity in production are further quality features of a good manufacturer of grinding wheels.
