Qihong’s CBN tools have achieved a revolutionary improvement in impact resistance, and their cutting performance and application scope have both made significant breakthroughs.
Cost Analysis of Using Cubic Boron Nitride Blades
(1) High cutting speeds: When machining hard cast iron with cubic boron nitride blades, significantly higher cutting speeds can be employed. The cutting speed can reach 800–1200 meters per minute, yet the flank face wears only 0.16 mm. In contrast, when using other cemented carbide tools, the cutting speed is only 6.6 meters per minute—just 1/9 of that achievable with cubic boron nitride tools.
Recommended Cutting Parameters for Machining Workpieces with Cubic Boron Nitride Inserts
By selecting appropriate cutting parameters for cubic boron nitride (CBN) inserts, it is possible to achieve both longer tool life and superior workpiece quality. It is recommended that the wear standard for the flank face of CBN inserts be set at 0.3 to 0.5 mm (taking the lower value for finish turning), and regular regrinding is advised.
How to Extend the Service Life of Cubic Boron Nitride Cutting Tools
Cubic boron nitride tools, often referred to as PCBN tools, are widely used in industrial machining due to their hardness, which is second only to that of diamond and significantly higher than that of other materials. Cubic boron nitride tools are highly efficient and long-lasting cutting tools that can generate substantial economic benefits. However, improper usage can lead to significant waste. In daily use, pay attention to the following points:
