摘要： The method for machining the helical grooves of an hour-glass screw for a compressor or expander of the screw and gate-rotor type, uses a tool (8) slidably mounted in a passageway (19) of a rotatable tool-holder shaft. The tool (8) will, during machining, move just like a tooth of the gate-rotor which will mesh with the screw in the future compressor. However, for progressive machining of the screw grooves, the tool (8) is progressively moved outwardly of the tool-holder form an almost fully retracted position in the tool-holder, towards the illustrated fully extended position, corresponding to the extent of a tooth of the gate-rotor. When the tool (8) engages the screw blank, the tool (8) is securely clamped by a piston (29). When the tool (8) is out of engagement with the blank (this happens during part of each revolution of the tool-holder), piston (29) is released and a gear (24), meshing with a rack (23) of the tool (8), is rotated for an incremental extension of tool (8). This allows a stable positioning of tool (8) during machining even if the extension of tool (8) out of passageway (19) reaches 45 % or more of the length of the tool.

摘要： A method for manufacturing a rotor includes the following operations: the clamping of a workpiece in a grinding machine; the performance of one or more cylindrical grinding operations whereby a rotor shaft section is ground to the desired diameter with a cylindrical grinding disk; the performance of one more profile grinding operations whereby a rotor body is profiled with a profile grinding disk. During the manufacture of the rotor in the grinding machine, the workpiece is not undamped and the cylindrical grinding operations and the profile grinding operations are done with the same grinding machine.
