Finishing Machining Hardened Steel Ball Screw with Brazed PCBN Indexable Inserts
1. Halnn Tools Rough Turning Ball Screw with Halnn CBN Turning Inserts full form better wear resistance
Halnn Tools accurately grasps the changing pulse of the times and continuously strives to develop high-quality, high-performance tool products that can quickly meet increasingly diverse needs. Based on the long-term cultivation of accumulated technical strength and the most advanced technology development capabilities, the concept of "cubic boron nitride monolithic crystal insert" for rough machining has been proposed, and it has adapted to the cutting requirements of modern "high speed, precision machining".
Cubic boron nitride integrated polycrystalline blade, strong impact resistance, good wear resistance, high hardness, high efficiency of turning ball screw. This is a machining effect unmatched by cemented carbide tools and ceramic tools, which is 4-5 times the grinding efficiency.
