As the name suggests, laser cutting involves the focus of a laser beam directed through a nozzle to a targeted area of material that is to be cut. The focused beam cuts via a combination of heat and pressure. It essentially melts and then ejects molted material away while leaving a small kerf in its wake. Its primary application is for use in cutting metals, many vital to fabrication processes like stainless steel, carbon steel, brass, aluminum, and copper. In fact, laser cutting offers optimal precision cuts for all ferrous and non-ferrous metals.
Advantages of Laser Cutting
Laser cutting services offer many unique benefits over traditional methods of cutting. The process is a thermal-based subtractive method that cuts through materials by melting, burning or vaporizing the workpiece material. It is used in the fabrication of products for numerous industries. The process CNC driven laser cutting applications can produce highly complex geometries through materials of all thicknesses. Most notably, it ensures a precise, clean, smooth-edged finish suitable for cutting a broad selection of material. As one of the most popular fabrication techniques, it can be used for countless applications. One of the key advantages of laser cutting is high accuracy and precision, which guarantees clean cuts with tight tolerances that produce smooth-edged finishes. The laser focuses on a desired region of the material and cuts, impacting a very small heat-affected zone. The result is imperceptible warping or distortion from changes that commonly occur to microstructures from other methods of cutting. The process is very fast and can be repeated with high levels of precision. That precision also reduces the kerf width, which enables tighter nesting, which in turn makes more use of the material and lowers scrap waste and as well as material costs.
Laser Cutting vs. Laser Punching
Laser punching is another subtractive fabrication manufacturing method. Punch presses are fitted with uniquely shaped turrets that strike metal with brute force, into a die that literally “punches” and creates a design through the material. Either the punched-out material can be used, referred to as blanks, or the metal sheets or panels with intricate designs can be used for such applications as housing a laptop or tablet. Punch presses can be smaller mechanical machines or advanced automated systems powered with CNC technology offering the flexibility and versatility to produce complex designs.
Both laser cutters and punch presses benefit from CNC (Computer Numerical Control) powered programs. CNC technology provides the highest levels of control over the fabrication of products. Once the CNC program is loaded, the laser cutting system or punch press can perform intricate, exact cuts with precision, accuracy, repeatability at increased speed. Geometric designs once considered improbable are now possible with CNC programming.
Choosing the ideal laser cutting service can depend on a number of factors that can range from better resources and more customer experience to higher quality and competitive pricing. These are all important factors in finding the right service for your company. With the many benefits that laser cutting offers, selecting a full-service shop that is familiar with your industry will ensure you find the ideal company for your job.
