Patent ID: 7140948

Claim:
Machine ( 10 ) for machining an elongate workpiece ( 14 ) provided with cutting teeth ( 12 ) arranged along the elongate workpiece with the teeth including a cutting tooth with a tooth tip, in particular for grinding bandsaw blades, comprising: a machining device ( 26 ), a feed device ( 38 ), a workpiece-fixing device ( 42 ) and a workpiece-guiding device, the workpiece-guiding device has a first guide and a second guide for slidably receiving the elongate workpiece which is a continuous saw blade, the machining device is located between the first guide and the second guide, the first guide includes multiple spaced apart first supports to support the saw blade, the second guide includes multiple spaced apart second supports to support the saw blade, the first supports are adjustably mounted to vary the spacing therebetween and the second supports are adjustably mounted to vary the spacing therebetween to cooperatively support at variable locations the entire length of the saw blade, the machining device ( 26 ) having a tool ( 28 ), in particular a grinding wheel, which is rotationally drivable via a tool spindle about a tool spindle axis (A), for machining the workpiece ( 14 ), the rotationally drivable tool ( 28 ) being displaceable relative to the workpiece ( 14 ) by means of a multiaxis arrangement with axis guide, wherein the feed device ( 38 ) has a feed head, which is displaceable along a feed axis (X) and by means of which the feed device positions the workpiece ( 14 ) in a desired position relative to the machining device ( 26 ), wherein the workpiece-guiding device guides the workpiece ( 14 ) along a predetermined guide path to bring about the desired position by means of the feed device ( 38 ), and the workpiece-fixing device ( 42 ) fixes the workpiece by clamping the workpiece on reaching the desired position, characterised by a common central machine block ( 18 ), on which the machining device ( 26 ), the feed device ( 38 ), the workpiece-fixing device ( 42 ) and the workpiece-guiding device are mounted.
