TOS Hostivař is a Czech manufacturer of universal and surface grinding machines. Their grinding machines can be used for internal and external grinding, and can be operated manually or automatically.
BUB E CNC is a fully CNC controlled grinding machine with controlled axis X (wheel head in-feed), Z (longitudinal table feed), and axis C (work head swivel).
This machine is primarily designed for controlled longitudinal and plunge-cut grinding of cylindrical and conical external surfaces. Matter of course is a shape-grinding and grinding of various transitions among different diameters. Grinding of face surfaces can also be performed as well as internal grinding of cylindrical and conical surfaces with internal grinding attachment (another version of grinder). Workpieces may be clamped between centers or by flying mode into the chuck. A drive headstock, grinding spindle, and upper table may be rotated for grinding of cones. It is possible to grind between centers or with live spindle with the workpiece being clamped into chuck or in the magnetic board.
Both grinding wheel head feed and table feed are controlled by ball screws and servomotors. BUB E CNC is designed for grinding workpieces up to 500 kg.
