Synchronized ER tap adaptor

The AB735 synchronized tapping adaptor from Walter compensates for axial movement and pressure during tapping, allowing users to increase threading productivity while increasing tapping tool life. The synchronization of a machine, (i.e., the rotation of the spindle in relation to the feed) is one of the main reasons for tool wear in thread production. With the AB735 Walter offers a flexible solution which minimizes the axial forces that occur during this process.

The adaptor, which can be used in all common ER collet chucks, also means that fewer number of tools are required. Further, thread flank wear is minimized since these are strained less when chamfering. The sleek, short, compact design also makes it possible to use the adaptor in tight spaces.

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

The low maintenance requirements and high level of process reliability of the adaptor also have additional positive effects, for example, by reducing the risk of breaking the threading tool. Walter offers the quick-change system for all tool types with or without internal coolant. The AB375 accommodates internal coolant of up to 725psi (50 bar), as well as external coolant supply. It is particularly well suited to applications in the series production of threads and/or applications where lack of synchronization results in a high tool wear rate.
