Plastic Core Cutter TWIN K–2000

The TWIN K-2000 is able to cut tubes of each kind of plastic materials in progressive, single index action
Available with outside and interior chamfering.
Closest tolerances and perfect cutting surfaces are guaranteed by inline finishing.
The entire operational sequence is PLC-controlled and fully programmable.

Working Method and Machine Equipment

Working Method

The required cutting lengths are programmed and the machine started.
Tube advance is actioned by servo-motor according to the programmed length.
First a trim cut is made and discharged then the complete core is divided into the corresponding length.
The first and last trim cuts are ejected to the rear of the machine separate from the cut sections.

The machine is equipped with

Siemens Operating Touch Panel
PLC – control Siemens S7
Self - diagnostic - system with fault indication at the terminal.
Dual-cutting-system programmable via servo devices.
Station 1: Nose cutting tool for cutting the plastic core
Station 2: Narrow square for chamfering and smoothing
Very easy tube set-up by programming the corresponding data for core- and toolset data
Minimum - Jet-Lubrication of tooling for polished cutting surface and cooling.
Upper and lower guiding rollers with automatic adaptation to the cores diameter.
Upper guiding roll powered by separately engine
3-jaw-chuck suitable also for heavy core cutting.
Positionable servo-indexing
Discharging device for the last trim cut with automatic adaptation to the cores diameter.
Sorting device for first and last trim cuts.
Toolset for one core-ID with expanding cutting head
Levelling elements for exact alignment of the machine.
