There are many features to look for in a https://www.hmlasercutter.com/product/garment-fabric-laser-cutting-machine-hm-sm-series/. A high-quality control system, Special CAD/CAM software, and a fiber or high-wattage laser are all important for a quality machine. The focus of the cutting head is placed on the surface of the work piece and a laser beam is used to cut the material. These features help you make precision cuts anywhere on the work bed. The following are some common features of a https://www.hmlasercutter.com/product-category/nonmetal-laser-cutting-engraving/.
High-quality control system
A high-quality control system for a metal laser cutter is important for its precision. When cutting stainless steel, for example, the laser will not work properly unless it is using nitrogen as an auxiliary gas. The auxiliary gas helps with the cutting process, and it will also affect the edge roughness and burr generation. Here are some of the features of a good quality control system. Listed below are the most important ones to look for.
Special CAD/CAM software system
CAD/CAM software systems are the backbone of a metal laser cutter. They help users position parts on sheet metal and program laser machines. Though the main functionalities of these solutions are similar, some points are critical for good productivity. First, the software must calculate laser head trajectories accurately and ensure that the cut-out part is placed in the correct orientation. Moreover, it should also ensure that the head is not overcutting the part.
High-wattage lasers
The quality of a cut is directly related to the power and frequency of the beam. The laser’s initial burning time and intensity distribution are important factors that determine how smooth the cut is. For thick materials, it is also important to keep the cutting vector outside the material. Some industrial lasers are mounted on a robotic arm and can cut outside the product’s plane. High-wattage metal laser cutters can achieve this.
Fiber lasers
When it comes to metal laser cutting, fiber lasers are an excellent choice. The cutting edge is consistently shaped regardless of the thickness of the material, and fiber lasers have a more difficult time maintaining consistency as the material gets thicker. Therefore, if you’re in the market for a metal laser cutter, you should consider fiber lasers. Here’s why. Listed below are some of the advantages and disadvantages of these lasers.
Neodymium lasers
These neodymium lasers use a solid gain medium that is doped with neodymium. The gain medium consists of silicon dioxide or a similar substance. The laser beam is then pumped to a desired wavelength by a flashlamp or diode laser. The most common Nd:YAG laser is yttrium aluminum garnet, and other neodymium-doped materials include yttrium orthovanadate and yttrium lithium fluoride. The laser beam from these materials can be focused to cut metal and plastic materials.
Titanium
When choosing a Titanium laser cutter, it is important to understand the advantages and disadvantages of this metal. Titanium is a strong metal and the fastest laser cutters can achieve high-speed cutting. However, the material can be brittle and will require the use of additional materials, such as auxiliary gasses. Using an oxygen-free cutting gas can help prevent this problem. Oxygen-free cutting gases are more suitable for titanium plates, as they can yield higher cutting speeds without any slack.
Nickel-based superalloys laser
The advantages of a nickel-based superalloys laser cutter over conventional sheet-cutting methods include increased mechanical properties and ease of cutting. However, a conventional sheet-cutting process is not effective for cutting this metal due to difficulties associated with resolidified layers, dross adhesion, and heat-affected zone. The quality of a laser cut depends on many parameters, such as the cutting speed, the composition of the sheet material, and its thickness. In addition, the mode of operation of the laser beam affects the quality of the cut. The cutting quality of nickel-based superalloy sheets was investigated using a pulsed Nd-YAG laser beam machining system.
