Traditional metal cutting is generally accomplished by grinding wheel cutting, oxygen cutting, shearing machines, and other processing methods. This type of cutting method has large cutting seams, low accuracy, rough cutting surfaces, severe thermal deformation, and limited cutting patterns. The processing form is single, requiring secondary processing. The commonly used punch presses require mold making, which has a short service life, high purchasing costs, high noise, serious pollution, poor working environment, and high production costs in small batches. All of these have become bottlenecks restricting the development of the metal cutting industry.
Metal laser cutting machine is recognized as the most effective processing method to replace traditional metal cutting due to its outstanding advantages such as high accuracy, fast speed, small heat affected zone, low use cost, low maintenance costs, and wide material adaptability. Compared to CNC presses, laser cutting machines do not require mold opening, and complex graphics can be easily cut without secondary processing, resulting in higher cutting quality.
Metal laser cutting machine cutting without burrs, wrinkles, high accuracy, superior to plasma cutting. For many electromechanical manufacturing enterprises, because modern laser cutting systems with microcomputer programs can easily cut workpieces of different shapes and sizes (the workpiece drawing can be modified by the paper industry), they are often preferred over punching and molding processes; Although its processing speed is slower than die stamping, it does not require mold consumption, no need to repair the mold, and it also saves time to replace the mold, thereby saving processing costs and reducing product costs. Therefore, on the whole, it is more economical. On the other hand, from the perspective of how to adapt the mold to changes in the design size and shape of the workpiece, laser cutting machine cutting can also play its advantages of accuracy and good reproducibility.
As a preferred manufacturing method for laminated molds, there is no need for advanced mold makers and the cutting and operating costs of laser cutting machines are not expensive, which can significantly reduce mold manufacturing costs. An additional benefit of laser cutting for cutting molds is that the cutting edge of the mold will create a shallow hardening layer (heat affected zone), improving the wear resistance of the mold during operation. The non-contact characteristics of metal laser cutting machines bring a stress free advantage to the cutting and forming of circular saw blades, thereby improving their service life.
