Main features of JJ series mechanical automatic straightening machine

l  Measuring system with high reliability and high precision

l  High speed data acquisition unienables accurate data sampling.

l  Floating rotating center which caclamp workpieces without loosening during measuring and straightening processes, thus increases its working frequency

l  Comparing with hydraulic straightening machine, this JJC machine has advantages of high cost performance, less floor space, cleanermore safe and reliable

l  The machine has multiple protective mechanisms for electric,machinery and software to offer utmost safety during production.

l  The maximum correction limit function can protect workpieces from fracture caused by over-correction.

l   Versatile for many kinds of workpiecesAveraged changing time <10min.

l   Friendly man-machine interactiointerface cashow bending value of workpieces by digital or bar chart display

l  Fully opened straightening parameters setting interface - icaadjust operating parameters any time as required

l  The operation software is based on MS Windows systemall straightening process cabe observed dynamically

l  The machine has auto diagnosifunction

l  It has self-adaption & adjustable system of correction value.

l  The machine has straightening point selection function that can set straightening sequence of measurement points.

l  After straightening processthe straightening machine can judge automatically if the workpieces qualified and give sound & visual indication accordingly.

Typical workpieces
