UNI 45-2000
backUniversal Multi ID – Paper Core Cutter UNI 45 – 2000
For burr-free cutting of cardboard cores of different diameters on the same cutting mandrel.
The mandrel fits the whole range of diameters.
Tool change is not necessary!
Working Method and Machine Equipment
Working Method
- The tubes are fed onto the cutting mandrel.
- The cutting mandrel´s diameter is smaller than the inner diameter of the core and therefore suitable for the whole range of core IDs.
- The cutting length is entered at a terminal then the machine is started by a button.
- First a trim cut is made, next the core is divided into the corresponding cutting length programmed.
- A pusher ejects the separate pieces off the mandrel.
The machine is equipped with
- Operating Terminal for programming the required cutting length and amount of pieces.
- Positionable Knife-Holder incl. circular knife and absorber unit.
- Driven Knife with speedcontrol, for cutting also heavy walled cores.
- Positionable Servo Axis for cutting unit
- Auto-scanning off wallthickness, damages of knives are prevented.
- Auto-scanning off parent core length, the machine adapts automatically.
- Discharging unit for cut sections.
- Jet - Lubrication of knife for polished cutting surface and cooling.
- Cutting mandrel 68mm Ø (OD 2.677´´) with easy to change nylon-bushes.
- Levelling Elements for correct alignment of machine.
- Safety Devices according CE - conformity
