valuable questions to ask

how do i choose the right technology?

Material type and thickness determine which technology is best suited. Fiber lasers can cut steel, CO2 lasers can cut steel, wood and acrylic while waterjets can cut just about anything. Lasers are fast, waterjets are slower however lasers are limited with thickness while waterjets can cut very thick materials. Before deciding on which technology would be best, ask yourself what materials and what thicknesses you need to process, this will steer you to the correct technology.

what is the difference between fiber and CO2 lasers?

Fibre lasers cut faster and are cheaper to operate than CO2 lasers. In cutting thin sheet metals, fibre lasers can cut almost 3 times faster than CO2 lasers and operating costs are typically half of that required to operate a CO2 due to having much lower electrical consumption and the absence of laser gases and mirrors. In addition, fibre lasers require much less maintenance. CO2 lasers have the capability of cutting wood and acrylics that Fibre lasers cannot cut.

Can you combine waterjet with plasma?

Yes, we can. This is very useful for applications that require both very tight and not so tight tolerances in the same part. The waterjet can precisely cut the critical contours while the plasma can cut the less crucial contours at a much faster speed.

Some cool things you should know

01.

CAD / CAM / nesting software

Computer-aided design (CAD) is the use of computers to aid in the creation & modification of a design. Computer-aided manufacturing (CAM) is the use of software to control machine tools in manufacturing. Nesting refers to the process of laying out cutting patterns to minimize the raw material waste. The output from the CAM software is usually a simple text file of G-code/M-codes, sometimes many thousands of commands long, that is then transferred to a machine tool fo processing.

02.

Waterjet

Waterjet cutting can be classified as a mechanical method. The energy generated by the movement of the water at a speed three times faster than the speed of sound is utilised both for pure water cutting and for abrasive cutting and is then applied to the part being cut in order to produce micro-erosion. Water jet cutting does not generate residual heat at the cutting edge and thus the physical properties of the material are not changed.

03.

fiber laser

A fiber laser is a laser in which the active gain medium is an optical fiber doped with rare-earth elements. Fiber lasers deliver their energy through an integrated flexible optical fiber and have a monolithic, entirely solid state, fiber-to-fiber design that does not require mirrors or optics to align or adjust. These features make fiber lasers easier to integrate and operate. The fact that the light is already in the fiber allows it to be easily delivered to a movable focusing element, which is important for laser cutting.

04.

CO2 laser

There are several types of high power CO2 lasers - slow flow, fast flow, transverse flow and slab lasers. A CO2 laser gas mixture is circulated, via a turbine, roots blower or vacuum pump, through an electrode structure, which creates electrical excitation of that mixture. The electrical excitation provides, via molecular collision, pumping of the CO2 molecules which in turn can be stimulated to release optical energy to the laser beam. The laser beam is then directed by mirrors, through the focussing lens, to the work-piece.

05.

Air bending

Air bending forms material by pressing a punch (top die) into the material, forcing it into a bottom V-die. Because it requires less bend force, air bending tends to use smaller tools than other methods. Air bending does not require the bottom tool to have the same radius as the punch. Bend radius is determined by material elasticity rather than tool shape.

laser - waterjet - press brake

Which technology is right? With a laser and waterjet, there is almost nothing that cannot be cut.

  • Any material
  • Any shape
  • Up to 200 mm thickness

Augment with a press brake to add value to your cut parts.
