TECHNICAL PARAMETER
This machine is full-automaticaIly controlled by PLC,the whole hydraulic transmission,drive hydraulic oil jar carry out and shear through centre pump station towards the hole,hydraulic pressure motor transmit power as main transmission,characteristic its reliable for to operate steadily by hydraullc pressure,Shear towards hole precision high,high output,low energy consumption,Section geometry form rule of the notch.Its hydraulic pressure trausmission,two sets of rectification correct and fit,the cut- off have a national patent.  
1) Base of machine is processed by planning machine and the locating pin of screw connects wall of machine stand. Panel can be formed with straightness, which guarantees the high accuracy. 2) Adopts hydraulic interlaced cutting which makes sure of the exact geometrical profile of formed panel. This cutting method causes no waste material.
3) Computer for measuring the length, hydraulic punching for the long holes at both sides and round holes in the middle, the distance between holes can be adjusted.
4) Arranges with leveling unit of 7 rollers, which assures the levelness of Z purlin.
