Three dimensional engraver´s profile milling which has been successful for severaldecades of years. A tracing pin serves to scan the metal or duroplastic template. The work piece can be milled at the same time, because there is a solid connection between the tracing pin, and a milling spindle. A put on milling unit 1:1 is, moreover, available as special equipment. Adaptation will take a few minutes time only. The perfect surface quality of the finished work pieces is beyond any competition. Even the slightest cavities get detected. You may, of course, also mill mirror-inverted and vary the sectional heights infinitely. Operators will be completely familiar with the system within less than a day. The die can be engraved infinitely reduced in size from 1:1,41 to 1:100
The machine is equipped with a reversing gear which allows a synchronous reverse rotation of model and work-piece. It results a mirror-inverted transmission from model to work-piece. This facts enables the production of symmetrical mirror-inverted workpieces (“Janus-form”).
