Machine Applications Centre Grinding Machines 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...

Machine Applications Centreless Grinding Machines C 250 and C 500 CNC models of grinding machines belong to product line C of fully numerically controlled centreless grinders. Their construction and high rigidity predetermine them for the accurate and high-performance grinding of external cylindrical surfaces in series and mass production, allowing for both plunge-cut (shape) and through-feed grinding. With the machine modular modifications, the number of controlled axes can be selected as needed for the particular type of work pieces to be ground, to the satisfaction of customer´s...
