Fields of application of CBN tools
At present, CBN cutting tools are widely used at home and abroad, especially suitable for cutting difficult-to-machine materials industries, such as automobile manufacturing industry (engine, crankshaft, brake disc, brake drum, etc.), mining machinery industry (rolling mortar wall, slag Slurry pumps, etc.), bearing gear industry (hub bearings, slewing bearings, wind power bearings, gears, etc.), roll industry (cast iron rolls, high-speed steel rolls, etc.), etc.
The characteristics of CBN tool cutting
1. Suitable for processing high hardness materials
Since the hardness of the CBN tool itself is second only to diamond, it is collectively referred to as a superhard tool together with diamond PCD tools. CBN tools are mainly suitable for processing high-hardness ferrous materials, high-hardness wear-resistant cast iron and powder metallurgy materials. The hardness is generally above HRC45.
2.Turning with large allowance possible
Integral CBN cutters can achieve large margin rough machining, and the cutting depth can reach 8mm, which can fill the entire blade, and the production efficiency can be doubled.
3.High speed cutting
Due to its good performance, CBN cutting tools can fully realize high-speed cutting, and can be perfectly combined with CNC machine tools to efficiently cut workpieces and greatly improve production efficiency. The cutting speed of CBN tool finishing can reach up to 1500m/min without considering the rigidity and clamping method of the machine tool. Gray iron enables high speed cutting with good finish and dimensional accuracy.
4.Dry cutting
Due to the high thermal red hardness of CBN tools, if coolant is added, the blade is prone to breakage due to a sudden drop in temperature. Therefore, dry cutting is generally used when CBN tools process workpieces, especially in the case of intermittent cutting. Dry cutting not only Save a certain cost and be environmentally friendly.
Moresuperhard provide quality CBN/PCBN blanks and all set grinding solutions for CBN tools.
During the production process of ceramic diamond grinding wheels, raw materials such as diamonds and binders need to strictly control humidity and temperature. Excessive humidity may cause raw materials to absorb moisture, affecting the bonding strength and hardness of the grinding wheel; while excessive temperature may cause volatilization or unstable quality of certain materials, thus affecting the overall performance of the grinding wheel.
Single crystal diamond cutting tools are high-performance tools made from single crystal diamond, known for their exceptional hardness, wear resistance, and thermal conductivity.Effective grinding methods include using diamond grinding wheels, laser grinding, and mechanical grinding with cast iron or steel discs, each with its own advantages and requirements. Moresuperhard offers various solutions and consumables for grinding single crystal diamond tools, ensuring efficient production and high-quality results.
