Alumina ceramic is a ceramic material with a-Al2O3 as the main crystal phase. Due to its high melting point, high hardness, heat resistance, corrosion resistance, and electrical insulation properties, it can be used under harsh conditions. Alumina ceramics have low prices and mature production processes. They are currently one of the ceramic materials with the largest output and the most widely used applications. They are mainly used in the fields of cutting tools, wear-resistant parts and bioceramics. In addition, it is also widely used in energy, aerospace, chemistry, chemical industry, electronics, etc. In particular, alumina porcelain 95 porcelain and 99 porcelain are one of the ceramic materials with the widest range of applications and the largest consumption, whether in structural ceramics or electronic ceramics.

Difficulties in processing alumina ceramics
Alumina ceramic has high hardness (HV1900~2100) and high brittleness (flexural strength 240~260MPa). It is a typical hard and brittle material that is difficult to machine. Its grinding processing cost is high, the efficiency is low, and the surface and subsurface after grinding Crack groups appear in the area, affecting the stability of the workpiece. These characteristics are not conducive to its practical application.

Grinding processing technology accounts for 80% of ceramic processing. Diamond grinding wheels are mainly used for grinding. During processing, the material in front of the abrasive cutting edge is extruded and peeled off to complete the grinding.
1. Resin-bonded diamond grinding wheels mostly use thermosetting resin, which has the advantages of low curing temperature and relatively simple preparation. It is mainly used for rough processing such as hole grinding, cylindrical grinding and surface grinding.
2. Metal-bonded diamond grinding wheels have strong bonding force with abrasives, good toughness, and can withstand large loads. They have been used in the fields of complex surface grinding of hard and brittle materials, precision ceramic parts, and ultra-precision grinding. However, metal-bonded diamond grinding wheels are expensive and require special dressing equipment for wheel dressing.
3. Ceramic bonded diamond grinding wheels have higher elastic modulus and lower fracture toughness. Its bonding strength is higher than resin bonded diamond grinding wheels, and its self-sharpening properties are better than metal bonded diamond grinding wheels. It is widely used in processing ceramics. , glass, carbide and other materials.
Moresuperhard have rich experience in grinding ceramic materials and we can recommand suitable grinding wheels for you.Moresuperhard have development different formulations grinding wheel for different ceramics materials.Three kinds of diamond grinding wheel including resin bond,vitrified bond and metal bond all can we supply.Moresuperhard provide diamond grinding wheel and diamond cutting wheel for different grinding machine like cylindrial grinding machine,surface grinding machine and milling grinding.
In modern manufacturing, tungsten steel (hard alloy) is widely used due to its high hardness and wear resistance. However, the requirements for tools when processing tungsten steel are extremely high, especially the selection of suitable grinding wheels is crucial in the grinding process. This article will share the case of us providing customers with high-quality grinding wheels and successfully solving their processing problems.
SG grinding wheels are suitable for grinding carburized steel. Their high hardness and self-sharpening properties enable them to effectively grind the high hardness surface of carburized steel, while low heat generation and good heat dissipation reduce thermal damage during the grinding process. In addition, the wear resistance of SG grinding wheels also helps to extend the service life of the grinding wheels and reduce grinding costs.
