A cubic boron carbide tool requires high speed or low speed turning, cooling off
Not too low. The outer circle of 30 is about 600 RPM. Too low a knife head is broken.I hope my answer will help you.
Cut at low speed. The harder the material is, the lower the linear speed (combined with the strength of the tool). It generally doesn't need cooling.
Think that the cubic boron nitride (PCBN) tool is as unresistant as a ceramic tool Early can only be used for the welding of cubic boron nitride tool machining allowance in 0.3 mm below the finish, and intermittent processing easy collapse knife, caused many users to distrust. As valin superhard HLCBN series product is suitable for intermittent processing, rough machining of hardened steel, broke the cubic boron nitride tool cannot be used in the myth of the intermittent turning hardened steel, enjoying high reputation in academia superhard cutting tools.
The use of the cubic nitride boron cutter is wrong: One, the cubic boron nitride (PCBN) lathe tool is suitable for high-speed machining Due to early cubic boron nitride tool is made from abroad, had been the main welding compound types, a large number of applied to processing the hardness above HRC45 hardened steel, wear-resistant cast iron, heat resistant alloy HRC35 above and under HRC30 and other blades are difficult to processing pearlite grey cast iron. It is characterized by the ability to achieve high speed machining (see table below) : From the table as you can see, it is higher than cemented carbide tool under the linear velocity of a lot of times, so now a lot of users have been mistakenly assume that cubic boron nitride tool can only be suitable for high speed machining, is used in CNC machine tools and machining center, not suitable for low speed processing.
