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.
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.

<< ：The difference between transverse turning and longitudinal turning
The silicon carbide substrate preparation process mainly includes raw material synthesis, silicon carbide crystal growth, ingot processing, ingot cutting, cutting piece grinding, grinding piece polishing, polishing piece cleaning, etc.Among them, the key and difficult points of preparation are mainly the crystal growth, cutting, grinding and polishing links, which are the key points and difficulties in the entire substrate production process, and become the bottleneck that limits the yield rate and production capacity of silicon carbide.
