0.83.5×670mm Slitting Unit

机组简介 Brief introduction


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.
