The RASACHECK A is an integrated device ingested into the sawing centre that serves as a universal length measurement module for different shapes like round, square and rectangular tube. The machine automatically ejects all reject parts quickly.The mechanical measurement system tests every work piece with the use of two measuring plates. The rejected parts are detected and they will be automatically ejected from the process. Then, they will be put together in a separate container that keeps the batch from contamination considering the tolerance parts. The unit serve to be an interface for electronic capture and analysis of measurement data. On request, fully automatic check of the tube-end geometry can be incorporated.
