Is the biggest characteristic of cubic boron nitride cutting tool in high temperature environment also can keep the characteristics of high hardness, mainly used for processing iron, used in industrial production is becoming more and more widely, so the pros and cons of cubic boron nitride cutting tools how to distinguish? Today to explain for everybody from the two aspects:
One, from the point of use to judge the merits of the cubic boron nitride cutting tools, high quality of cubic boron nitride cutter has two characteristics:
1, impact resistant performance is good, especially in the field of rough machining, the blade won't crack when using, not broken, this is the safety of using cubic boron nitride cutting tool is the most basic guarantee.
2, wear-resisting performance is good, high efficient processing at the same time, to substitute the carbide cutting tools and the low cost of ceramic blade, this is the assurance of cubic boron nitride cutting tools use budget.
Second, from a manufacturing perspective the pros and cons of cubic boron nitride cutting tools:
1, high purity, high purification rate of raw materials, reliable standard body synthesis process, the two directly determine the performance of cubic boron nitride cutting tools. Of course, this also is cubic boron nitride cutting tools on the market price of the biggest reasons for the uneven.
2, grinding, as a result of cubic boron nitride cutting tool is not like carbide insert with complex groove and coating performance mainly depends on the tool body performance, and the grinding process and precision directly decided when cutting the microscopic properties. So using peripheral grinding machine, tool cost is more many, but the quality of the cubic boron nitride cutting tools and durability are a class at the meeting.
3, strict testing means, in addition to the dimensional accuracy and surface quality, cubic boron nitride cutting tool production process, is the most easy to produce waste under the electron microscope detection of micro defects. Blade is invisible to the naked eye in the micro defects is cubic boron nitride cutting tools used in the process of collapse edge trigger, easy to cause when using a cutter knife problem.
