Description

technical field [0001] The invention relates to synthesis equipment and technology of nanometer silicon carbide products. Background technique [0002] The linear speed of existing nano-silicon carbide products is generally 35m / s, which can meet the grinding requirements when used on domestic grinding machines. The bonding agent used in the existing nano-silicon carbide products is a sintered bonding agent. The main feature of the sintered binder is that the liquid phase formed during firing only accounts for a part, and there are many crystals in the microstructure, which belongs to the multi-phase system. Commonly used raw materials for sintering binders are clay, feldspar, quartz, and sometimes a small amount of talc is added. The approximate fluctuation range of its chemical composition is: SiO255-71%, Al2O317-22%, Fe2O30.2-1.5%, MgO0.5-2.5 %, K2O+Na2O 4-13%. [0003] In the raw materials used for sintering binder, the content of flux agent is less, and the content of...

Problems solved by technology

The resin bonded diamond grinding wheel has high grinding efficiency and good self-sharpening, but its rigidity is insufficient, heat resistance is low, and the shape retention is not good, which inhibits the performance of the CNC grinding machine

Metal-bonded diamond grinding wheels have good rigidity, heat resistance and surface retention, but they are not easy to dress and have relatively low grinding efficiency, so they are not used in CNC grinding machines
