Recommended PCBN Cutting Tools for Powder Metallurgy Workpie

Due to the unique advantages of powder metallurgy (porous structure), it is widely used in transportation, machinery, electronics, aviation and other fields, especially in the field of automobile manufacturing. At the same time, the difficulty of powder metallurgy processing lies in the porous structure. Due to the existence of porous pores, the hardness value also fluctuates in a small area. Even if the measured macroscopic hardness is HRC20-35, the hardness of the particles of the component parts will be as high as HRC60, and these hard particles will cause micro-fatigue and sharp wear of the cutting edge of the tools.
In view of the above processing difficulties, Halnn Tools has professional and efficient processing of CBN tools. The specific tool solutions are as follows:
1. Valve seat
Process: finishing process; commonly used models: DCGW11T304, etc.; Halnn Tools CBN tool models realize high-speed cutting and obtain higher finish.
 
 
2. Pulley
Process: Finishing process; Halnn Tools recommends composite CBN tools; compared with imported tools, it is cost-effective and has stable cutting performance.
 
The case is as follows:
         Particle hardness: HRC62
         Processing material: sintered powder metallurgy
         Tool model: BN-K10 CCGW09T304
         Cutting parameters: Vc=150m/min
                   Fr=0.15mm/r
                   ap=0.35mm
         Processing method: dry cutting
The comparison effect is as follows:
Materials Vc Ap Number of passes
Halnn BN-K10 150m/min 0.35mm 1
Other CBN inserts 150m/min 0.2mm 2
 
 
 
3. Hip joint support cover
Process: Finishing process; Halnn Tools recommends composite CBN tools, which not only improve production efficiency, but also reduce costs compared to imported tools.
 
The case is as follows:
         Workpiece hardness: HRC35
         Processing material: cobalt-chromium alloy
         Tool model: BN-K10 DCGW11T304
         Cutting parameters: Vc=210m/min
                   Fr=0.10mm/r
                   ap=0.15mm
         Processing method: dry cutting
The comparison effect is as follows:
Materials Vc Tools life Flank wear
Halnn BN-K10 210m/min 230 pcs/edge 0.4mm
Other CBN inserts 180m/min 200 pcs/edge 0.5mm
