Quality Assurance

The quality assurance system for our products comprises all areas which contribute to achieving the quality goals. It is based on legal requirements, customer requirements and the internal isel Germany AG quality requirements. The quality assurance system ensures the production processes are manageable and that products are only sent on to the next production step if they meet the respective specifications.

In 2011 isel Germany AG has established a quality management system in the scope of, development, production, sales and service of components and systems for automation:

QC 10 accuracy check
         
   

The QC 10 system allows the routine inspection of our machines.
The measurement of the circularity detects geometric and control machine faults such as for example squareness, contouring errors, guide clearance, straightness faults and backlash. The system is traceable according to DIN ISO 9000.

... position measurement

Position measurement is the most common measurement performed on machines. The system captures the positioning and repeat accuracy by comparing the position value indicated by the machine and the actual position captured by the Laser Interferometer System.
         
         
.... tilt angle measurement

On machine tools and coordinate measuring equipment the cause for positioning faults is oftentimes the tilt of the axis. With the Abbe effect the faults continue to increase with an increasing distance from the axle location
     

... Measuring the dynamic behaviour

The software for dynamic measurements allows for motion sequences, speeds, accelerations, vibrations and the capabilities of servo drives
to be determined.
