Characteristics

Universal grinding machines UB 50 – 500 kg form the middle line of our production. UB 50 – 500 kg are based on the basis of time-tested design, complemented by modern features. These grinding machine are used for grinding of workpieces max. Diameter of 320, 400 and 500 mm and a max. Length of 4000 mm, clampend between centers or overhung in a chuck with the possibility to use of internal grinding device. During grinding, the machines can be controlled manually or work in fully automatic grinding cycle (grinding multiple diameters (multicycle), plunge grinding or lengthwise grinding, grinding of convex or concave diameters with automatic grinding wheel dressing). Workpieces are clamped between centers, overhung in chuck or on a magnetic permanent plate. The original hydraulic system was replaced by a pneumatic one. The machines are intended for precise and high-performance grinding of individual pieces but also for large series of workpieces..
