Tungsten Carbide Screw-tap’ Development

Tungsten carbide screw-tap’ successful application depends on the stiffness of the tool holder and control precision feed. For most of the processing methods, these processing conditions for granted. But for tungsten carbide screw-tap’s tapping, these conditions are only just become a reality.

Machine control technology continues to progress, has been able to achieve with the rotation of the spindle synchronization control the feed, which can no longer use the soft tapping head. In addition, the use of thermal loading and hydraulic tool clamping chuck can increase the rigidity of the tool, but also significantly reduce run-out than when using flexible tapping head. Concentric rotation of the tool holder within 3μm. Despite the large clamping force precision telescopic precision (TGHP) chuck performance and less on heat-mounted hydraulic tool chuck, but when applied to tungsten carbide screw-tap’s tapping is also very effective.
