0.8～3.5×670mm縱剪機組
0.8～3.5×670mm Slitting Unit
機組簡介 Brief introduction
0.8～3.5×670mm縱剪生產線采用全數字交流變頻調速系統，PLC及全液壓控制，對金屬帶料進行縱剪后，再按一定的張力卷繞成卷。剪切速度，卷取電流，長度設定，單機調整與全線運行控制全部集中于控制臺上。
0.8～3.5×670mm slitting unit adopts AC motor speed control system, PLC and full-hydraulic control. The machine unit is applied for slitting the metal strip, and then rewinds the strip according to the certain winding tension. The slitting speed, the coiling current, the length setting, the single machine adjustment and automatic running control are all collected in the console.
