Pre-cutting CZ purlin machine
The CZ purlin machine is 90% automatic degree, sizes changing automatically, C and Z changing automatically, servo motor high speed driving, Machine only use pre-cutting system, no post cutting system.
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.
