There is a difference between steel tubes, stainless steel tubes and aluminium tubes.
Steel and Stainless Steel
For steel and stainless steel ducts (square and rectangular), the angles should be drawn as follows:
- outside radius = 2x wall thickness (The value '2' is an average value of the size of the radii mentioned in the standards).
- inner radius = 1x wall thickness.
For aluminium tubes (square and rectangular), the angles should be drawn as follows:
- outside radius = 0 to 0.6 mm radius (acute angle).
- Inner radius = 0 mm radius (acute angle).
247TailorSteel cuts 2.5D. This means that the cutting edge of the ducts is perpendicular to the material (centre-orientation). In case of tubes, it is directed towards the centreline. Some examples are discussed later in this manual. The software of the 247TailorSteel converts the 3D-cutting edges into 2.5D-cutting edges.
Wall thickness options:
Maximum weight of the product per metre: 32 kg.
Maximum length to be laser cut from one piece: 5,800 mm.
In the case of machining or holes, a minimum size of 0.7 x material thickness is required. This is to ensure the cutting quality.
The tolerances on the cut contour, centring of the cut contour and on the total length amount to +/- 0.2 mm. The tolerance is strongly influenced by a number of factors, such as:
