Starting points and lead-in length

Starting points can be specified in Sophia®. 247TailorSteel determines the position if the starting points have not been specified.

Startpunten en lead-in length

The starting point must be drawn at least 3 mm outside of the entity or at the top (see image). A distance of at least 5 mm applies to sheets that are thicker than 10 mm.

When placing the starting point, note that there must be space perpendicular to the starting point for insertion. A starting point must therefore not be placed in the middle of a narrow slot.


Holes in corners

When cutting holes into corners, specific hole diameters are maintained. The table below shows the desired hole diameter according to sheet thickness.

For example, a sheet thickness of 0.5 mm to 3 mm should have a hole diameter of 1 mm. At the opposite end of the spectrum, a sheet thickness of 15 mm to 25 mm should have a hole diameter of 4 mm. See the table for a complete overview.

Holes in corners
Plate thickness Hole diameter
0.5 t/m 3.0 mm 1.0 mm
4.0 t/m 6.0 mm 1.5 mm
8.0 t/m 12.0 mm 2.0 mm
15.0 t/m 25.0 mm 4.0 mm

Engraving

247TailorSteel only engraves functionally, for positioning or identification. Only the upper side of the sheet can be engraved. Foil-coated materials cannot be engraved.

Please refer to STEP and/or DXF/DWG file specifications for character specifications.


Silk technology

Silk machining technology can be selected for edge rounding and deburring. This can result in scratches on the surface.


Tolerances

 

Dimensional tolerances of cut contours. Cutting is in accordance with the ISO9013 norm, unless stated otherwise in the table below.
