It is a fully CNC controlled grinding machine with controlled axis X (grinding wheel head in-feed), Z (longitudinal table feed), and controlled axis C (grinding wheel peripheral speed). The grinder is designed for controlled grinding of rotation cylindrical and conical external surfaces of medium-weight workpieces by longitudinal or plunge-cut grinding methods. As a matter of course, form grinding and grinding of various transitions among different diameters can be performed. The grinder also allows grinding of face surfaces and grinding of cylindrical and conical internal holes with the use of internal grinding attachments. The workpieces may be clamped between centers or by flying-mode into the chuck. The drive headstock as well as grinding wheel head may be inclined for grinding cones. It is possible to grind either at the centers or in the flying-mode with the workpiece clamped in the chuck or on the magnetic plate. The grinding wheel head and table are moved in the line by ball screws and servomotors. The BHM CNC is designated for workpieces weighing up to 1 000 kg. Cylindrical grinding machine BHM CNC can be additionally equipped with automatic balancing system, in-process gauge, axial probe, super finish attachment, automatic (electric) rests, X Z ruler etc.
