Abstract
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.
Claims20
A method for manufacturing a screw rotor, the method comprising:
- performing a first clamping by clamping a workpiece that has already been partially processed to have a shape of a rotor with a first clamp;
- performing one or more cylindrical grinding operations on the workpiece with one or more cylindrical grinding disks;
- performing one or more profile grinding operations on the workpiece with one or more profile grinding disks, wherein the one or more cylindrical grinding operations and the more profile grinding operations are performed by the same grinding machine;
- switching by the grinding machine between the one or more cylindrical grinding operations with the one or more cylindrical grinding disks and the one or more profile grinding operation with the one or more profile grinding disks;
- and
- automatically controlling both the one or more cylindrical grinding operations and the one or more profile grinding operation of the manufacturing of the rotor by a controller of the grinding machine.
A grinding machine for manufacturing a screw rotor, the grinding machine comprising:
- at least a first clamp configured to clamp a workpiece that has already been partially processed to have a shape of a rotor;
- one or more cylindrical grinding disks;
- one or more profile grinding disks;
- a switching system configured to enable switching between grinding operations of the grinding machine, including switching between one or more cylindrical grinding operations with the one or more cylindrical grinding disks and one or more profile grinding operation with the one or more profile grinding disks;
- and
- a controller configured to automatically control the grinding operations to manufacture the rotor;
- wherein the grinding machine is configured to perform both the one or more cylindrical grinding operations and the one or more profile grinding operation by the controller controlling the switching system.
