There three types of Laser machine:
1) laser marking machine
2) laser cutting machine
3) laser welding machine
Our typical product line of laser marking and laser engraving has been growing manufacturer’s speeds. These laser marking machine systems employ any of the fiber or CO2 lasers of diverse strengths depending on the application. The combination of speed, performance and versatility of these laser marking machine systems cannot be matched by any other laser marking machine technique. This makes sure no matter the size of the company or application laser marking machine can provide an affordable system which is easily integrated into any production facility.
Welcome to Unique Laser Engravers, leading laser marking machine manufacturers of laser marking machine & laser engraving marking machine, laser marking and machine.
There are three main types of lasers used in laser cutting machine. The CO2 laser is suited for cutting, boring, and engraving. The neodymium (Nd) and neodymium yttrium-aluminum-garnet (Nd-YAG) lasers are identical in style and differ only in application. Nd is used for boring and where high energy but low repetition is required. The Nd-YAG laser is used where very high power is needed and for boring and engraving. Both CO2 and Nd/ Nd-YAG lasers can be used for welding.
CO2 lasers are commonly “pumped” by passing a current through the gas mix (DC-excited) or using radio frequency energy (RF-excited). The RF method is newer and has become more popular. Since DC designs require electrodes inside the cavity, they can encounter electrode erosion and plating of electrode material on glassware and optics. Since RF resonators have external electrodes they are not prone to those problems.
CO2 laser cutting machine are used for industrial cutting of many materials including mild steel, aluminum, stainless steel, titanium, paper, wax, plastics, wood, and fabrics. YAG lasers are primarily used for cutting and scribing metals and ceramics.
In addition to the power source, the type of gas flow can affect performance as well. In a fast axial flow resonator, the mixture of carbon dioxide, helium and nitrogen is circulated at high velocity by a turbine or blower. Transverse flow lasers circulate the gas mix at a lower velocity, requiring a simpler blower. Slab or diffusion cooled resonators have a static gas field that requires no pressurization or glassware, leading to savings on replacement turbines and glassware.
Laser welding machine is usually done without filler metals so parts need to have good fit-up with a gap less than 15% of the thickness of the thinnest component. Parts should be relatively clean since the Laser welding machine is very fast with no time to burn-out contaminants. Shield gas is required for more reactive metals but many alloys can be welded in air.
Both types of Laser welding machine usually employ fiber optic beam delivery which simplifies welding system design and creates a much more consistent and robust welding process. Fiber optics have standard lengths of 5-50m and have standard focusing end-effectors called Focus Heads that take the laser beam from the fiber and produce a focused spot on the work piece.
