Laser sheet metal cutting, engraving and tube cutting

Laser cutting is a thermal cutting process for procesing sheet metal. The laser beam is created by the laser source (resonator), conducted by mirrors or a transport fiber in the machine cutting head where a lens focuses it at very high power on a very small diameter. This focused laser beam meets the sheet metal and melts it.

Advantages of laser cutting over mechanical cutting vary according to the situation, but two important factors are the lack of physical contact (since there is no cutting edge which can become contaminated by the material or vice versa), and precision (since there is no wear on the laser).

Cutting with laser produces identical parts consistently, maintains close tolerances, can be used on a wide range of materials. Some materials are also very difficult or impossible to cut by more traditional means. Laser cutting offers low cost for prototype and short runs since no physical tooling is needed.

Waterjet cutting and engraving

At its most basic, water flows from a pump, through plumbing and out a cutting head. It is simple to explain, operate and maintain. The process incorporates extremely complex materials technology and design.

Waterjets enable you to cut a variety of applications with ease. Whatever the shape, dimensions, or material, our easy-to-use software makes the job easy.

Whatever your business - automotive, aerospace, stone and tile, tool and die, gaskets, fabricator, or job shop - you can cut metal, stone, plastics, composites, glass, ceramics, rubber and more.

Waterjets cut accurate, clean edges that allow for tight nesting and reduced scrap - saving you money through greater material utilization.

We added waterjets to our industrial services and operations alongside with other cutting technologies such as laser, milling and oxy-fuel flame. We found it  to be a tremendous asset to our operations - enhancing both productivity and profitability.

Oxy-fuel flame cutting

In oxy-fuel cutting, oxygen is used as the cutting gas. Cutting is initiated by heating the edge of the steel to the ignition temperature, and then torch blows extra oxygen at higher pressures into the workpiece. The chemical reaction releases large amounts of energy causing the metal to burn and blowing the resulting molten oxide through to the other side. The oxygen chemically combines with the iron in the ferrous material to instantly oxidize the iron into molten iron oxide, producing the cut. Initiating a cut in the middle of a workpiece is known as piercing.

Oxy-fuel cutting - arguably one of the most time-honored and trusted methods of cutting steel - is the tool for you if you'll be cutting thicker metals. One limitation to keep in mind, however, is that oxy-fuel cannot cut stainless steel and aluminum. Oxy-fuel is particularly effective on ferrous (iron-containing) metals. Oxy-fuel can efficiently cut even the thickest metals.

V-bending

V-bending is shaping of sheet metal by straining the metal around a straight axis. A bending operation compresses the interior side of the bend and stretches the exterior side. Flanging, hemming, and seaming are all bending operations.

Bending is used as a sheet metal forming process to produce angled parts, sheet profiles, tubes and workpieces for shipbuilding and apparatus manufacturing. Apart from these parts, profile stock is also used to make rings for various fields of application.

Rapid prototyping or 3D printing

Rapid prototyping, also known as solid freeform fabrication or 3D printing, is an additive layering process. A three-dimensional computer model of a part is sliced into layers by the SLS rapid prototyping system’s computer program. Each slice is then fed to a processor which in turn directs a laser in X and Y axis directions, as well as controlling the beam output power, to sinter through CO2 laser (SLS) the cross section (slice) of the part. After the slice is completed the system's build mechanism vertically repositions incrementally (Z vector), usually between .07mm and .15mm per layer. This process is repeated until the vertical height of the part is completed. Build time can range from one hour to many depending upon the part volume, mass and Z height.

SLS materials (thermo-set plastic) are suited for direct functional applications where performance demands robust resistance to chemical, heat, wear, abrasion, flexibility, and internal/external surface pressures.

CNC vertical machining center

CNC machining is short for computer numerical control machining. It refers to a computer controller that reads code and instructions and drives a machining tool in order to make a product according to specific requirements. Imagine a robot that can make several different products based on a specific set of instructions given to it.

CNC machining allowed manufacturers to do curve cuts as easy as straight cuts. Three dimensional structures were also as easy to build with the introduction of CNC machining into the industry.

Human intervention in the making of products was reduced dramatically. Their intervention on several manufacturing steps have either been reduced or removed completely.

Machining processes that have traditionally been done on conventional machine tools that are possible (and in some cases improved) with CNC machining centers include all kinds of milling (face milling, contour milling, slot milling, etc.), drilling, tapping, reaming, boring, and counter boring.

CNC milling technology

Precision milling enable production of simple and complex parts, in a fast and high-quality manner at competitive prices. In the production the latest software for machine operation is used and there is also possibility of machining all types of steel, aluminium, inox, and bronze.

Advantages of CNC processing:

  • lower production price,
  • speed, precision and constant quality.
