how to distinguish disadvantages of cubic boron nitride tool?
Time：2018-04-27
The most important feature of CBN tool is that it can maintain high hardness under high temperature environment. It is mainly used for processing iron parts. Its use in industrial production is more and more extensive. Then the advantages and disadvantages of cubic boron nitride tools How to distinguish it? Let us explain to you from two aspects today:
First, from the perspective of use to determine the advantages and disadvantages of cubic boron nitride tools, high-quality cubic boron nitride knife has two major characteristics: 1, good impact resistance, especially in the roughing field, when used without chipping, not broken This is the most basic guarantee for the safety of cubic boron nitride tools. 2, With good abrasion resistance, high efficiency machining, it can replace carbide tools and ceramic inserts at low cost. This is an economical guarantee for the use of cubic boron nitride tools.
Second, from the manufacturing point of view, the advantages and disadvantages of cubic boron nitride tools: 1, high purity, high purification rate of raw materials, reliable and standardized embryo body synthesis process, these two items directly determine the performance of cubic boron nitride tools. Of course, this is also the biggest reason why the price of cubic boron nitride tools on the market is uneven. 2, Grinding, because the CBN tool does not have a complex groove type and coating like the carbide blade, the performance depends mainly on the tool body performance, and the grinding process and precision directly determine the microscopic properties of the cutting. Therefore, the use of peripheral grinders, although the tool cost is increased a lot, but the quality and durability of cubic boron nitride tools will be on a grade. 3, strict inspection methods: In addition to dimensional accuracy and surface quality, the production process of cubic boron nitride tools, the most likely to produce waste is the microscopic defects under the electron microscope. Microscopic flaws that are not visible to the naked eye at the cutting edge are the fuses of the chipping holes during the use of the CBN tool, which can easily cause the problem of tool cutters during use.
The above two points are the simplest and most practical method to distinguish the advantages and disadvantages of cubic boron nitride tools. If you have any questions about the actual use of cubic boron nitride tools, please contact us
