Abstract
For producing hectically profiled workpieces (1) the helical profile (2) is first of all prefabricated by a milling treatment and is then finished by a grinding treatment of the profile surface. To achieve optimum machining qualities in an economic way, the grinding treatment is performed with a grinding tool (6, 12) adapted to the milling tool (3, 9) for the milling treatment in terms of shape, size, position of the axis of rotation and cutter arrangement.
Claims3
A method of producing a workpiece with a hectically profiled circumference, which comprises the steps of
- (a) first prefabricating the hectically profiled circumference in a milling treatment with a milling tool having a cutter arrangement by moving the milling tool about the circumference in a helical path while rotating the tool about an axis of rotation, and
- (b) subsequently finishing the hectically profiled circumference in a grinding treatment with a grinding tool having a cutter arrangement by moving the grinding tool about the prefabricated circumference in the helical path while rotating the tool about an axis of rotation,
- (1) the milling tool and the grinding tool matching with respect to shape, size, position of the axis of rotation and cutter arrangement.
