Grinding Machines BUB 40(50)B PRACTIC, PROFI

   The high-performance grinding machines of BUA series (Practic and Profi versions), BUB series (Practic, Profi and Multi versions) and BUC series (Practic, Profi and Multi versions) are designed for precise grinding of several external cylindrical surfaces of different diameters, their adjacent faces and transition radii on work pieces. In another version, they are suitable for grinding of internal cylindrical and tapered surfaces, and surface grinding of their adjacent faces. In its basic version, the grinder can be used for plunge-cut grinding or longitudinal grinding, with a fixed or oscillating table, successive plunge cutting with subsequent traverse regrinding.
