ABSTRACT:
A centerless cylindrical grinding machine, for through-feed and in-feed grinding of various workpieces (8), has a first driven positioning axis XSfor a grinding spindle head (2) with a grinding wheel (1) and a second driven positioning axis XR, running parallel to the positioning axis XS, for a regulating spindle head (4), with a regulating wheel (3). The positioning axes XSand XRare arranged perpendicular to the rotation axes (5, 6) or the grinding wheel (1) and the regulating wheel (3). A workpiece support (7) on a carriage (12) and an inner- or outer-acting wheel-true device (9) are arranged between the grinding spindle head (2) and the regulating spindle head (4). During operation, the grinding spindle head (2), the regulating spindle head (4), the workpiece support (7) and the wheel-true device (9) are located within a safety housing (15). The carriage (12) may be adjusted along a driven positioning axis YWwhich runs at right angles to the positioning axes XSand XR, along a carriage track (13) and may be moved to a position outside the safety housing (15). The invention has the advantages that the machine is not just a simpler and therefore cheaper, but is also more reliable in operation and permits easy retooling.
