For laser cutting the quality of the cut in various setups of the parameters for cutting cannot be changed. It is always necessary to set the optimum parameters for cutting in order to achieve the optimum quality of the cut. Again, this depends on the thickness of the material. In general it can be said that a cut up to a thickness of 5-8 mm is smooth, even and without scale, while with increasing thickness characteristic laser grooving appears, as well as minor scaling and weld-on spots on the bottom side. At the upper border of the thickness the grooving is quite distinct and negative features can also be quite substantial on the bottom side (again it depends on the amount of heat introduced). If so requested, we can clean up the piece.

For stainless steel it is possible to use, in the place of nitrogen (which gives a shiny quality cut), oxygen as an auxiliary gas, which brings relatively significant cost savings of about 20%. The quality of the cut, however, is much worse, the cut is black, oxidized and coarse.

HOW MUCH DOES A 1 METER CUT COST, ONE OPENING…? The cost of cutting depends on: - Type and thickness of the material
- Complexity of the cut form, amount of burn off and opening
- Batch orders, total volume of long-term cooperation
- Operational demands
- Requests for cleaning, packaging, etc.
In view of the large amount of factors affecting forming costs, it is not possible to provide an objective "price list, informative….." prices for a cut of 1 m, etc. We will quickly prepade an exact offer for you based on your inquiry. The inquiry should include:- The forms of the pieces (including any specifications about what should and should not be cut - for example, in case of exact openings, modifying diameters for threads, extras for cutting, etc.), including requested tolerances (mainly if the laser possibilities of +/- 0.1-0.2 mm approach) for bent components, which is advantageous for adding shapes - for the form of the order see Forms and Geometry of the Cut
- The expected amount of parts - for long-term volumes, it's good to fix a minimum amount for individual orders
- The exact specification of grade and thickness of the material and information about the request for the order, including or without material
- Any additional requirements for treatment, packaging, producing test samples, etc. Any additional requirements for treatment, packaging, producing test samples, etc.
- Required term for manufacturing orders or jobs - especially express ones
- Contact for the inquiry - as much as possible, including a concrete name
Of course, we're happy to work on even incomplete orders, but processing the offer takes longer and leads to possible distortions.
In any case we always try to offer very agreeable prices and we are ready to negotiate about pricing, delivery and payment conditions. ^ Up
