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 within a grinding machine, the workpiece having 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, wherein the one or more cylindrical grinding operations are one or more cylindrical abrasive grinding operations and wherein the one or more cylindrical grinding disks are one or more abrasive 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 profile grinding operations are one or more profile abrasive grinding operations and wherein the one or more profile grinding disks are one or more abrasive profile grinding disks, wherein the one or more cylindrical grinding operations and the more profile grinding operations are both performed by the 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 operations with the one or more profile grinding disks;
- and
- controlling both the one or more cylindrical grinding operations and the one or more profile grinding operations 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 for performing one or more cylindrical grinding operations on the workpiece, wherein the one or more cylindrical grinding disks are one or more abrasive cylindrical grinding disks;
- one or more profile grinding disks for performing one or more profile grinding operations on the workpiece, wherein the one or more profile grinding disks are one or more abrasive profile grinding disks;
- a switching system configured to perform switching between grinding operations of the grinding machine, including switching between the one or more cylindrical grinding operations with the one or more cylindrical grinding disks and the one or more profile grinding operations with the one or more profile grinding disks, wherein the one or more cylindrical grinding operations are one or more cylindrical abrasive grinding operations and wherein the one or more profile grinding operations are one or more profile abrasive grinding operations;
- and
- a controller configured to 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 operations by the controller controlling the switching system.
