Application of Flexible Tapping Tool Holders in the Wind Power Industry - BIG DAISHOWA
Application of Flexible Tapping Holder in the Wind Power Industry
In recent years, the wind power industry has been a booming sector. The wind turbine hub serves as one of the important components of power generation equipment. The connection area between the hub and the blades contains dozens of threaded connection holes of various sizes. The tapping of these threaded holes has the following two characteristics:
- M36x4 thread machining with 6H grade accuracy.
- Dozens of threaded holes on a single hub require machining, necessitating a stable tap service life.
BIG Solution: AUTO-E Type Flexible Tapping Holder
To meet the machining requirements of a major wind power enterprise, BIG provided an AUTO-E type tapping holder with torque protection. Compared to rigid tapping holders, this flexible tapping holder has a certain amount of axial stretch/compression allowance, which can steadily improve tap service life. Simultaneously, the collet of the BIG AUTO-E series tapping holder has a built-in torque protection mechanism, effectively preventing tap breakage caused by wear or chip clogging. This significantly improves tap service life and reduces the risk of workpiece damage.
