Cutting Tools Scalping Cutter
Scalping cutters are brazed cutters roughing continously copper alloy sheets rolled in hot rolling. Roughed copper alloy is applied to connector terminal or lead frame material for electronic equipment.
Even for high-strength and difficult-to-cut copper alloy, our scalping cutter can scalp the surface due to high-strength cemented carbide and excelent brazing technology and contribute our customer's productivity improvement.
- ・Cemented Carbide with high strength (15 times longer tool life than previous products).
- ・Even for high-strength and difficult-to-cut copper alloy, our scalping cutter can scalp the surface due to excelent brazing technology.
- ・It is possible to produce TiN-Coated Scalping Cutter for improvement of welding.
