A centerless cylindrical grinding machine, for through-feed and in-feed grinding of various workpieces ( 8 ), has a first driven positioning axis X<SUB>S </SUB>for a grinding spindle head ( 2 ) with a grinding wheel ( 1 ) and a second driven positioning axis X<SUB>R</SUB>, running parallel to the positioning axis X<SUB>S</SUB>, for a regulating spindle head ( 4 ), with a regulating wheel ( 3 ). The positioning axes X<SUB>S </SUB>and X<SUB>R </SUB>are 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 Y<SUB>W </SUB>which runs at right angles to the positioning axes X<SUB>S </SUB>and X<SUB>R</SUB>, 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. |
