Bluetooth technology makes thread rolling faster and improves surface finish

The ES 16 thread rolling head uses Bluetooth communications technology between the head and control system on a CNC machine tool to control the rolling cycle and monitor the process. It will roll form threads between 12 and 22 mm diameter and up to 29.6 mm thread length in-cycle on almost any CNC machine tool. It can be used either statically or in rotating applications and be mounted on the machine via shank or flange fittings. The thread rolling process is significantly faster for producing external threads and, because the material is cold formed under mechanical pressure, a stronger thread with an improved burnished surface finish is achieved. Within the rolling head is an integrated power amplifier, a contact sensor and a magnet to control the rolling cycle which is initiated automatically from the CNC control system through the Bluetooth wireless interface. The on-board, long life battery that powers the lifting magnet to actuate the head is guaranteed to perform more than 10,000 work cycles and can be quickly exchanged and recharged
