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.
