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.
Evaluation of circuit board quality and process improvement requires slicing as a basis for objective inspection and judgment. Slice analysis using metallographic equipment is an important means to check the thickness of PCB/PCBA internal circuits, number of layers, through hole aperture size, through hole quality observation, PCB/PCBA solder joint cavity, interface bonding status, and wetting quality evaluation.
Moresuperhard offers resin diamond cutting discs and metal diamond cutting discs specifically for cutting in the glass industry. It can be used to cut glass optical devices such as quartz glass, K9 glass, coated glass, etc. It can also be used to cut various glass tubes, glass spouts, high borosilicate glass tubes, capillary glass tubes, quartz glass, and crystallized glass.
