Transmission or crankcases, chamber heads, or water-driven parts – they are weighty and complex to deal with, just like the examination of their surfaces. With the Series 2200 CNC estimating station for huge parts, Mahr’s designing group has fostered an estimating station that reviews surfaces completely consequently – in a small portion of the time that would be expected for manual estimation.
With the Series 2200 CNC estimating station with six situating tomahawks and a test arm evolving unit (TWE), unpleasantness and form elements can be naturally and dependably reviewed at practically all focuses on huge parts – even at challenging to-arrive at estimating areas. ” Some estimating focuses must be reached with specific test arms, and this requires a test arm change. The TWE test arm changing unit deals with this completely naturally, so the estimations are done without interference,” makes sense of Karl-Josef Gödecke from the Mahr ServiceCenter and is liable for application innovation in the surface region. A maximum of 292 features can be identified on a component in this manner within 2:15 hours.
Short paths, fast results
After a brief training period, users of the measuring station are able to operate it reliably thanks to the user-friendly CNCplus software. They can likewise rapidly deal with the test plans thanks to the quick situating choices for individual estimating focuses. The quick availability of the measurement results permits any necessary intervention in the production process. Because tool change intervals are extended, this results in lower costs because scrap rates are reduced. On account of the dynamic vibration damping framework, the CNC estimating station can likewise be incorporated straightforwardly close to the creation line – brief distances and quick experimental outcomes are ensured,” says Gödecke.
Automatic measuring sequences
Because of the completely programmed groupings, the administrator just needs to situate the part with the lift in the pneumatically bracing apparatus and read the DMC code through a laser scanner. This starts the related estimating program, and the administrator can give himself to different undertakings. The information from the examined DMC codes is naturally moved to the log header. As a result, inaccurate or incomplete logging is ruled out, and clear traceability is guaranteed. A table with tolerance bars displays the comprehensive log of the measurement results. As per the client’s explicit information structure, they are traded to the particular organizers and records. It couldn’t be less difficult! On the other hand, the same component would require more than 16 hours of manual testing. It would likewise require a reliably elevated degree of focus with respect to the analyzer to guarantee that he neglects no estimating focuses and plays out all estimations dependably.
Conclusion: Fully automatic measurements are completed seven times faster and take the tester only five minutes – instead of 16 hours or 960 minutes.
