Automatic cutting for tube in straight lengths

Blending quality, high standards and new technologies we deliver excellence in production of automatic cutting machine for tube in straight lengths.

Our automatic tube cutting machine is the best option for medium-to-large production quantities and ideal for optimizing overall production efficiency in terms of speed and waste. With the automatic version of the machine, the operator has only to place the straight lengths in the tube magazine. Its loading, measurement, displacement, optimization of the cut and unloading of the finished parts are done automatically by the machine.

 

Auto tube cutting machine

 

CSM Machinery offers two types of automatic cut to length machines, based on the required cutting system and on the level of automation:

  • Score and break system developed to eliminate the typical problems of the orbital cutting systems, in particular its ability to cut the tube without causing a deformation of the tube in correspondence with the cut edge. The cut, in fact, is carried out through the combined action of a scoring tooth (realized with three keen tooling) which removes progressively materials along a circular section of the cylindrical wall, reducing only the wall thickness, and of a clamp which breaks the segment of the tube.

    Technical characteristics

    Material of the tube to be cut steel, stainless steel, copper, aluminium
    Tube thickness 0,3 - 1,00 mm
    Outer tube diameter (to be defined) 6 -22 mm
    Max. length of tube to be cut 6100 mm
    Cutting length to be defined (mm)
    Cutting tolerance for cut lengths up to 1500 mm ±0,8 mm
    Cutting tolerance for cut lengths between 1500 mm and 4300 mm ±1 mm
    Capacity of the automatic feeder with diameter 7,5 mm 50 pcs.
    Space available in the feeder hopper 440 mm
    Min. length to be cut 100 mm
    Min. length of tube scrapped per bar (for tubes with outer diameter over 10 mm) 65 mm
    Min. length of tube scrapped per bar (for tubes with outer diameter below 10 mm) 340 mm
    Installed power 3 kW
    Voltage 400 V /3 phase /50 Hz 
    Pneumatic supply 6 bar
    Set up time when changing tube diameter 10 - 15 min.


    Score and break system

  • Cut with guillotine (hydraulic) with subsequent punching to eliminate the "heart shape" deformation caused by the cutting operation. This punching operation takes place without the need for an operator, as a strip unloads the cut bar in the punching transfer.

    Technical characteristics

    Material of tubes to be cut steel, stainless steel
    Thickness of the tube to be cut 0,3 - 1,0 mm
    External tube diameter 6 - 22 mm (to be defined)
    Max. length to be cut 6000 mm
    Cutting length To be defined (mm)
    Cutting tolerance 0,5 - 1 mm
    Installed power 12 kW
    Voltage To be defined (V)
    Time to change cut length with the same diameter 4 - 5 min.
    Time to change tube thickness  4 - 5 min.
    Time to change tube diameter 5 - 10 sec.

 
Moreover, CSM offers an automatic tube cutting line with the possibility to interchange the score and break system with the circular saw cutting system, and vice versa. This version of the machine allows to cut tubes with a different range of diameter and thickness in a single machine. In fact, the circular saw cutting system permits to cut tubes with bigger dimensions than the ones cut with score and break system. 

 

 

Advantages of the automatic cutting line are:

  • Numerical controlled feeder, for maximum tube length 6000 mm (available in any length) that measures the lengths of each bar before it enters in the cutting unit.
  • Possibility to set the feeder by setting a number of production batches, each with different cutting measures. This is made in order to cut:

- Pieces with different measurements from the same bar (optimization of the bar)

- Pieces with the same measure from the bar.

- The edges of the tube, to eliminate defects or to bring to length tubes too much long. 

  • Minimum waste pieces (optimization): the machine measures the length of the tube and so it is possibile to load tubes with different lengths and to set a three-length cutting program.
