NOVELTY - The work center has a fixed mounting (1) and a carrier (2) with six adjustable-length struts (3) connected to each other. The pivot points (T1, T2, T3) of three struts on the carrier form a first engagement plane and those (T4, T5, T6) of the other three form a second one spaced out from the first. The pivot points (G1, G2, G3) of three struts on the mounting form a first engagement plane and those (G4, G5, G6) of the other three form a second one spaced out from the first. The connecting lines between pairs of carrier pivot points are parallel to each other. USE - For milling, boring, turning, grinding etc. ADVANTAGE - greater mobility of carrier.
