Shapes - Geometry of the cut PDF Print E-mail

What shapes can be cut with water jet?

It's possible to cut all shapes that can be transferred in final form to the CAD format *.dwg and comply with the circular cross-section of the jet (waterjet d = 0.15 - 0.30 mm, abrasivjet d = 0.8 - 1.5(2.0) mm).



The magnified drawing illustrates the limitations of shaping in sharp internal corners with the circular cross-section of the jet.

Furthermore it is possible to produce also complicated „3D“ cuts under an angle up to 45°.

Does beveling occur when cutting with water jet?

In most cases a certain amount of beveling occurs when 2D cutting with waterjet or abrasivejet, although mostly to a maximum of 1-1.5 degrees.

A. - A very slow cut or cutting soft material - the jet manages to "grind down" its natural conical shaped mark.


B. - The optimum balance between the speed of the cut, resistance and the thickness of the material - the jet is maintained in a cylindrical shape for the whole time it passes through the material and beveling does not occur.


C. - A very quick cut or cutting in material with higher resistance - the jet cannot "grind down" the material, not even in its input diameter and the cut finishes going downwards



Thanks to the 5-axis moving cutting head and the Progres-Jet technology it is possible today to eliminate the bevel almost to zero. The cutting head leans out so the cut on the product is square and the bevel will be on the scrap material – the proces sis fully controlled by the control system also on more complicated cuts.


How to give shape to the cut

The program for processing NC codes for cutting is done as an upgrade to the CAD program, and that's why the optimum start is with a CAD file stored on some electronical medium (or sent by e-mail) in the formats *.dwg, *.dxf. There are also import filters available for formats wmf, sat, eps, pcx, 3ds, tif, gif, but using them is often problematic and leads at a minimum to changes in the scale of the drawing. It's also possible to work with *.cdr, *.ai and several other files. Precise dimensions of the drawing or schematic are also very helpful. It's even possible to use concrete patterns - designs or documentation for scanning - a sharply printed or drawn picture. For creating signs, shapes, ornaments, etc., we can cooperate using our wealth of experience, knowledge of the technology and our own creative ingenuity.
