Producing more threads per tool 31 August 2020

The synchronisation of a machine – the rotation of the spindle interacting with the feed – is one of the most important reasons for tool wear when producing threads. Walter AG says its AB735 synchronous threading adaptor is a flexible solution to minimise the axial forces that occur during this process.

The adaptor, which can be used in all common ER collet chucks, reduces wear forces during tapping and thread forming, meaning that fewer tools are required. Thread flank wear is particularly minimised since these are strained less when chamfering. The lean, short design also makes it possible to use the adaptor in tight spaces such as in lathes or turn/mill centres.

More cost-effective than comparable systems, but just as gentle on tools, the AB735 synchronous threading adaptor maximises tool performance. In addition to the minimised wear, the modular design of the adaptor also contributes to the cost-efficiency, as exchangeable front pieces for different thread sizes or tool diameters (ER16 to ER32) can be used with the same collet. This also fits in all ER adaptors without requiring further investments.

The low maintenance requirements, and high-level of process reliability of the adaptor, also have a very positive effect, such as reducing the risk of breaking the threading tool. Walter offers the quickchange system for all tool types with or without internal coolant supply. It is particularly suited to applications in the series production of threads and/or applications where the machine’s synchronisation is resulting in a high tool wear rate.
