Tripet MUS 100 Universal External and Internal Grinding Machine. The MUS 100 was designed specifically for tool-making in the horological and instrument making sector. The machine consists of a work-headstock mounted on a prismatic bed which is part of a larger casting forming a semi-circular sector. Somewhat resembling a giant Schaublin 102 grinding attachment, the grinding wheel carriage can be positioned at any angle between 0º and 45º in either direction relative to the work-head axis. The carriage itself consists of a screw operated top-slide perpendicular to a rack and pinion operated longitudinal slide

Here’s a unique US Burke Mill combined with a Burgmaster turret drill. The ad claims it converts in seconds. I question how many people want to rotate their turret mill back and forth for a turret drill. I guess this setup didn’t go over well. This was done about 1970, which was about the time Burgmaster, US-Burke, and Powermatic were all under the umbrella of Houdaille Industries.

Manufactured by Herman Beichle of Heidenheim-Schnaitheim, in Germany, the massively-built Combined Universal Die Milling Machine. The practical result of this arrangement was that, at one setting a job could be machined on several sides in a number of angular positions – and even radial surfaces that transformed into planes could be completed in one operation (i.e. both circular and straight milling was possible in one continuous operation) the makers claiming that the transition from one to another would be invisible on the finished article
