The choice then depends on the edge and the subsequent operations on the part. We write more about sheet metal laser cutting in our post <a href=\"https:\/\/ecad.com.pl\/en\/news\/12-kw-fibre-laser-at-ecad\/\">12 kW fibre laser at ECAD<\/a>.<\/p>\n<h2 id=\"maszyny\">Which machines stand behind each method<\/h2>\n<p>The machine determines what can be cut.

A waterjet cuts cold, so there is no such zone. This is important for materials that must not be heated.<\/p>\n<h3>Plasma cutting vs laser cutting<\/h3>\n<p>A laser-cut edge is usually smoother than a plasma-cut one, and small holes come out better on the laser. Our laser cuts structural steel with a high-quality edge up to 20 mm. With plasma, we pierce structural steel up to 32 mm and cut it up to a maximum of 38 mm. Above 20 mm, both our laser and plasma cut structural steel, so the deciding factors are the edge and what happens to the part next: if it goes to welding or a machine tool, plasma is often sufficient.<\/p>\n<h3>Waterjet cutting vs laser cutting<\/h3>\n<p>Both laser and waterjet cut metal sheets; on the waterjet machine we mainly cut steel. The laser is usually faster on thin sheet metal and better for fine patterns. We choose waterjet when the material should not heat up at the cut or when it is not metal: we cut metals on the laser, and plastics and stone with the waterjet.<\/p>\n<p>If any dimension has a tight tolerance, mark it on the drawing. We will select the method accordingly.<\/p>\n<h3>Example: flange from a 20 mm plate<\/h3>\n<p>On some production drawings from our archive, the designer enters the cutting method in the &#8220;Process&#8221; field. For this flange, the note reads: 1) waterjet cutting, 2) reaming of dia. 8.1 hole. Thus, the drawing specifies hole sizing after cutting.<\/p>\n<figure class=\"e-rysunek wpi-rys\">\n<div class=\"wpi-rys-kadry\">\n<div class=\"e-kadr\" style=\"--cx:.235;--cy:.5;--w:.45\"><div class=\"e-rysunek-okno\"><img class=\"wp-image-559\" src=\"https:\/\/ecad.com.pl\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda.webp\" width=\"2093\" height=\"731\" loading=\"lazy\" decoding=\"async\" alt=\"Drawing of a 260 \u00d7 260 mm flange from a 20 mm plate: top view with \u00d818 and \u00d88.1 holes and side view showing the 20 mm thickness.\" srcset=\"https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda.webp 2093w, https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda-300x105.webp 300w, https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda-1024x358.webp 1024w, https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda-768x268.webp 768w, https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda-1536x536.webp 1536w, https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda-2048x715.webp 2048w, https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda-480x168.webp 480w\" sizes=\"auto, (max-width: 2093px) 100vw, 2093px\" \/><\/div><\/div>\n<div class=\"e-kadr\" style=\"--cx:.9;--cy:.2;--w:.21\"><div class=\"e-rysunek-okno\"><img class=\"wp-image-559\" src=\"https:\/\/ecad.com.pl\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda.webp\" width=\"2093\" height=\"731\" loading=\"lazy\" decoding=\"async\" alt=\"Process field on the same drawing: 1) waterjet cutting, 2) reaming of dia. 8.1 hole.\" srcset=\"https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda.webp 2093w, https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda-300x105.webp 300w, https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda-1024x358.webp 1024w, https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda-768x268.webp 768w, https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda-1536x536.webp 1536w, https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda-2048x715.webp 2048w, https:\/\/ecad-com-pl.b-cdn.net\/wp-content\/uploads\/2026\/09\/rysunek-flansza-z-plyty-20-mm-ciecie-woda-480x168.webp 480w\" sizes=\"auto, (max-width: 2093px) 100vw, 2093px\" \/><\/div><\/div>\n<\/div>\n<figcaption>260 \u00d7 260 mm flange from a 20 mm plate.
