Tapping chucks and adaptors for the production of larger threads
The WFSL tapping system is used for the production of larger size threads as required in the turbine and reactor industries. The system can be used on both manual or numerically controlled machines.
The interchangeable flange mounting configuration of the chucks ensures the adaptability to a variety of machine spindle types. Also the length compensation on the chucks, plus the adjustable safety clutch on the adaptors, ensure effective and accurate tapping under the most difficult conditions.
In addition to this, the system is designed for rapid and easy adaptor change. The system is also available with coolant feed. The system is designed to accommodate tapping both with a single tap or series taps. When tapping with series taps, a narrow thread is produced initially, using the first of the series taps. Prior to the tapping of the full thread form, the plug tap, already locked into the adaptor, must be engaged by hand into the thread in order to prevent double threading.
When engaged the spindle drives with rota tion against the adaptor which clutches in automatically, then the final tapping can take place. Tapping chucks and adaptors are also available with internal coolant feed.
