Inspection of Screw Rotors for a Screw Compressor on Leitz Coordinate Measuring Machines


The rotors of screw compressors can be inspected on high precision 3D Coordinate Measuring Machines with the package QUINDOS Screw Compressor.

The measurement of the screw rotor can be done with the rotor mounted in horizontal as well as in vertical position. A significant advantage compared to single purpose screw rotor inspection systems using a rotary table!



The option QUINDOS Screw Compressor includes the following features:

  • Generation of nominal data and normal vectors for profile sections of male and female rotors
  • Transformation from axial to transverse sections, and back
  • 3D radius correction
  • Actual-nominal comparison of the screw rotor profiles
  • Best fitting of the profiles
  • Evaluation of the pitch, lead and the lead deviation along the length of the rotor
  • Pairing simulation of male and female rotors, with calculation of the gap The pairing simulation allows to measure a number of male and female screw rotors and then to match the best-fitting pairs.

No Rotory Table required for Screw Rotor Inspection!

With Leitz coordinate measuring machines and QUINDOS software a rotary table is not required for the measurement of screw compressors. Therefore various screw rotors as well as housings can be placed on a fixture and measured in one set up. This results in a dramatic increase in throughput and therefore significant lower inspection cost per compressor compared to conventional gear or screw rotor measuring systems.

Almost all leading manufacturers of screw compressors / screw rotors worldwide rely on Leitz Coordinate Measuring Machines and Leitz QUINDOS software for their quality control.

3D Coordinate Measuring Machines used for the inspection of screw compressors should have a probe head with High-Speed-Scanning capability and a small scanning probing error THP according to ISO 10 360-4, for example the Leitz PMM-C series.
