Characteristics
Universal grinding machines UB 63 – 3,000 kg form a number of our largest machine tools. UB 63 – 3,300 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 630, 850 and 900 mm and a max. Length of 6000 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 machines are intended for precise and high-performance grinding of individual pieces but also for large series of workpieces.
- Flexible grinding of medium-heavy to heavy cylinders and shafts.
