CZ purlin machine

Zhongtuo CZ purlin machine is fully automatic degree, sizes changing automatically, C and Z change automatically, servo motor high speed driving, Machine only use pre-cutting system, no post cutting system. Pre-cutting frame making machine can keep purlin production shape prefect. 

Advantage: Machine cutting No waste material, pre cutting machine is faster than post cutting machine. Pre-cutting machine no need to adjust the cutting blades.
