Processing and application of Jiejie CBN tool

The rapid progress of the global economic integration process has promoted the rapid development of the mechanical processing industry, bringing unprecedented opportunities for the tool industry. However, compared with the common material tools, CBN tool materials have inherent advantages. It is bound to make great achievements in this situation. CBN (Cubic Boron Nitride) is a kind of hexagonal boron nitride BN which is metamorphosed into cubic crystal under high pressure and high temperature. It does not exist in nature; CBN cutters use C, N or other special CBN particles. Ceramic as a binder is sintered at the same ultra-high pressure and high temperature; its hardness is only diamond, and CBN tool has far better stability and chemical stability than diamond, which is unmatched by diamond; CBN tool can Carbide processing of ordinary steel and cast iron for semi-finishing and finishing of hardened steel, chilled cast iron, superalloy, etc., processing accuracy up to IT5-IT6, surface roughness can be as small as Ra0.8- 0.2um can replace grinding.

Yan Jie's CBN tool is one of the typical representatives of this application. With its high hardness, long-term wear resistance, excellent thermal stability, good chemical stability, and second only to the thermal conductivity of diamond, the CBN tool can be re-grinded repeatedly. It is widely used in various mechanical processing links in aerospace, automotive, electronics, rail transit and other fields, which greatly promotes the rapid development of high-speed cutting and manufacturing industries.

In terms of milling, many mold manufacturers need to use 2-5 coated blades to finish large-scale stamping die finishing, but this type of processing is easy to produce tool marks on the finished surface. Therefore, whether or not only one blade can be used, the processing is completed while ensuring high-speed and high-efficiency processing and the finished surface is mirror-finished, which becomes the key to improving the processing precision and quality. In this regard, the new CBN mirror ball-end milling insert developed by Yan Jie can perform long-life high-speed cutting, which greatly shortens the processing time of large-scale stamping die finishing. The use of CBN materials extends the life of the tool. Almost all automotive exterior parts can be finished with only one blade, and the blades can be reground, saving machining costs. In the processing of cast iron stamping dies, the CJie CBN mirror ball-end insert has an extraordinary effect, which shows superior wear resistance and smoothness in the surface processing of traditional large molds.

In addition, the company's performance in the turning of CBN tools is also excellent. The JBN series is a cubic boron nitride material produced by Qijie Company using original technology. It has low affinity with iron materials, low reactivity, and can be cut more stably at high temperatures. It is a series of high hardness materials for iron series processing. The most ideal tool for ultra-high speed machining. At the same time, compared with the ordinary CBN cutter head, the machining life ratio of JBN is increased by 30% and the stability is relatively good. The CBN cutter can have significant processing efficiency when processing sintered alloy workpieces, and the original creation of Qijie JBN Cubic Boron Nitride is the first choice for CBN tools that process such difficult-to-machine materials.
