Superabrasives mainly refer to diamond and cubic boron nitride (CBN). Diamond is currently recognized as the hardest material in the world, while CBN ranks second in hardness. The exceptional hardness of these superabrasives far surpasses that of other materials, including traditional abrasives like corundum and silicon carbide, as well as hard tool materials such as tungsten carbide and high-speed steel.
Fenike Superhard Materials Co., Ltd. stands out as China’s leading manufacturer of CBN abrasives, equipped with advanced production technology and cutting-edge CBN abrasive techniques. The company holds a strong reputation and authority within the superhard materials industry.
Below is a comparison of the appearance of diamond and cubic boron nitride:
**Current Applications of Superhard Abrasives**
**Trends in the Development of Superhard Abrasives**
In recent years, both domestic and international superhard materials have been evolving toward higher quality, greater variety, and more specialized applications. Key development trends include:
1. **Single Crystal Synthesis**: By using various raw materials—such as graphite and different catalyst alloys—and employing diverse high-pressure, high-temperature synthesis equipment (like two-sided and six-sided presses), manufacturers can produce a wide range of single crystal products.
2. **Single Crystal Separation**: After synthesis, the crystals are sorted based on particle size, bulk density, strength, and toughness, allowing for classification into different types of single crystals suitable for specific applications.
3. **Surface Plating**: Following sorting, metal coatings (either single metals or alloys) of varying thicknesses are applied to the surface of the crystals through methods like electroless plating, electroplating, or vacuum plating. This creates diamond or CBN particles with distinct properties and purposes.
4. **Microcrystal Preparation**: CBN microcrystals are composed of numerous submicron-sized single crystal grains, typically ranging from 0.1 to 0.8 mm in size. These microcrystals exhibit isotropic properties, a dense structure, and excellent hardness and wear resistance.
5. **Thin Film Manufacturing**: Advanced vapor deposition techniques are used to grow ultra-hard material films with unique properties and large dimensions, opening up new possibilities for diamond-based applications.
**Major Production of Superhard Abrasives in the Country**
As the demand for high-performance materials continues to rise, the production and application of superhard abrasives are expected to expand further, driven by technological innovation and industrial needs.
Investment Casting
Investment casting, also known as lost wax casting, is a traditional manufacturing process that originated thousands of years ago. This process is utilised to create metal parts and components with complex shapes and intricate details. It is a cost-effective method to produce complex parts.
The process commences with the crafting of a wax or plastic pattern, an exact replica of the desired part. Our experienced engineers excel in designing tooling for creating these patterns. Once the tools are devised, we utilise 3D printing for initial rapid prototyping, which undergoes testing before the production phase. Subsequently, the pattern is coated with a ceramic slurry to form a shell around it. After the shell has hardened, the wax or plastic is melted out, leaving behind a cavity in the shape of the desired part. Molten metal is then poured into the cavity, filling the space vacated by the melted pattern. Following solidification, the ceramic shell is removed, revealing the finished metal part. Investment casting is esteemed for its capability to produce parts with tight tolerances, excellent surface finish, and intricate geometries.
Here at Taiyuan Simis Investment Casting Co., Ltd, we possess the capability to manufacture metal parts and components with extremely tight tolerances and complex and intricate shapes and designs, both internally and externally. We can cast metal parts and components with a wide range of materials using the investment casting technique, including stainless steel, carbon steel, cast iron, aluminium, and many more.
