PCBN CNGA Cutting Tools Inserts Interrupt Finishing Turning Machining Gear With High Speed
1. Difficulties in gear machining
There is no difficulty in processing the modulated component. However, it is difficult for the high-hardness gear after quenching, and some of the gears are interrupted. It can be said that it is more difficult.
Interrupt gears generally have oil holes or grooves in the inner hole or end face, and the hardness is high. In addition, the interrupt working condition requires high resistance to impact toughness and fracture resistance of the tool. A general cutting tool cannot process such gears.
2. Why choose Halnn CBN insert to turning the gear?
Halnn, a factory that produce super-hard CBN cutting tools, had developed BN-S20 cutting tools that can cut the gear tooth surface with heavy interrupt ,which was followed by the industry and the media. After that, with the continuous research and development, researched tools turning fnishing gears with medium-interrupted and interrupted, and there are two grade of continuous cutting tools, BN-H10 (PCBN) and BN-H11 (Brazing PCBN). There are also two grade of medium interrupted cutting tools, BN-H20 (Brazing PCBN) and BN-H21 (PCBN).
