The unique feature of an Escomatic is the ability to feed wire in coil form. The tools rotate as the stock is straightened and fed. For simple parts, you can attain high production rates and long runs. We just purchased an elderly D2 machine (5/32 in. capacity) and have learned quite a bit. The escomatic is a compact, robust mechanical marvel. The machines are cam driven though there are CNC models available. You will need cams for the stock feed and part profile as well as guide bushing, counter collet, custom ground form tools and straightener components. The tool head is the most critical component and can be quite costly to rebuild. Southwick and Meister (ph. 203-237-0000) can provide most of the parts you may need,or alternatively, you may get most anything you need as well as a wealth of information from Swisset Tool Company.
