 Reviewing the CO2 laser machine. This is Watson. Welcome to the world of CNC equipment. In the video we will talk about the insides of CO2 laser machines. You will learn what they consist of and what components to pay attention to when choosing a laser machine. The CO2 laser machine is an excellent tool for cutting and engraving. The laser machine is actively used in various fields of production. Souvenirs, promotional products, packaging for gifts, toys, woodworking, seals and stamps, decorative elements. Now let's move on to the most important thing. What is the laser machine made of? Our engineers recommend paying attention to which parts the machine is assembled from because it is a single mechanism where the quality of each part affects the quality of the final result. Let's look at the insides of the Watson machine which make it unique and popular among professionals. Machine bed. Vibrations occur during the operation of the machine which negatively affect the accuracy characteristics and quality of the final product. A strong bed eliminates vibrations. Ideally there should be a reinforcement frame inside the case for example as it is done with Watson machines. Housing thickness. The thickness of the housing should be at least 2 millimeters as it affects the rigidity of the machine structure. Watson machines have a housing thickness of 2.9 millimeters. Portal. The thickness and strength of the portal affect the preservation of accuracy characteristics during long-term operation of the machine at high speeds. Watson machines have a reinforced aluminum portal up to 7 millimeters thick at the corners. Engine location. If the y-axis motor is located in the corner of the housing this leads to geometry distortion during operation. When cutting holes with a diameter of 3 millimeters with the right location of the stepper motor the circles on the left side will be oval and on the right rounded. If the stepper motor with distribution couplings is placed in the center then such distortions are excluded. Gearboxes. Watson milling machines are equipped with quarter belt gears to remove excessive load from the engine which makes the engraving more accurate and the engine lasts longer. Belts. Belts are a vulnerable point of the machine if they are not reinforced they stretch or tear. Watson machines have reinforced belts with a toothpitch of 3m. They are not subject to overheating and stretching and provide a smooth edge when laser cutting. End sensors. Inductive end sensors are more reliable than mechanical ones since they are not subject to mechanical action. The operation of inductive sensors is not affected by dirt dust and resins unlike mechanical ones. Watson machines use FOTEC inductive sensors with a response distance of 5 millimeters which eliminates any collision of portal elements with each other. Blowing hoses. A weak point of low quality machines. At the place of attachment to the laser head the blowing hose breaks off if more than one bar is applied. To obtain a cut without burning deposits two bar is needed. Polyurethane blower hoses on Watson machines can withstand a pressure of up to 8 bar which is necessary to obtain a clean cut when cutting thick materials such as plywood with a thickness of 6 to 8 millimeters. Optics and mirrors system. Pay attention to the working head especially the lens attachment and the attachment of the head itself to the portal. The lens should be easily accessible which helps with maintenance. The screws on the mirrors for adjusting the optical path should be convenient even if you use a non-standard laser tube. Mirror mounts must move along all axes to adjust. Nozzle diameter. The diameter of the nozzle affects the quality of blowing and therefore the quality of work. If desired a machine with two types of nozzles for engraving and for cutting can be shipped to the customer. Lamellas and a cellular table. The anodized lamellas prevent the laser beam from shooting out onto the back of the material. The iron honeycomb table uses neodymium magnets to fix thin materials such as fabric and leather. Table lifting mechanism. The lifting table mechanism is equipped with a belt and chain hoist. Chain hoists are ideal for professional machine tools as they are less likely to break during operation. Watson tables equipped with chains that lift and lower a table with objects weighing up to 80 kilograms. For example, a stone. Garbage collection compartment. A machine tool manufacturer who thinks about his customers equips the machine with a garbage collection compartment. This increases usability and strengthens the body structure providing additional protection for the lifting mechanism of the table and improves smoke removal. Safety. The electrics of the machine and the water cooling system must be located in different parts. Placing them in one part can lead to a short circuit and equipment failure. Mounting the laser tube. Mountings with adjustment wheels allow to change the position of the laser tube without disassembly. All Watson laser machines from model 6.090 and above are equipped with such fasteners. Potentiometer. The potentiometer allows you to manually adjust the radiation power. This function provides more precise manual adjustment and extends the engraving capabilities, which allows the user to set values lower than programmatically possible. Advantages of laser cutting. Efficiency. Cuts at a speed of 500 millimeters per second and engraves at 700 millimeters per second. Accuracy. Watson machines have a positioning accuracy of a 0.03 millimeters and a beam diameter of 0.012 millimeters. CNC. The CNC laser machine ensures repeatability and accuracy. Durability. The life of the laser tube is 10,000 hours. Cleanliness. The laser gently and cleanly melts the material without dust and chips. Silence. Laser cuts without noise. Ease of use. The basic principles of working on a laser machine can be mastered in a few hours. Multi-purpose. CO2 laser machines work with a wide range of materials. Wood, plywood, MDF, chipboard, acrylic, pet, foam rubber and other plastics and polymers, rubber, peronite, stone and ceramics, mirror and glass, cardboard, paper and various fabrics, fur and leather. In conclusion, it should be noted that when choosing a laser machine, it is important to take into account its components and design features. Watson strives to continuously improve its machines based on feedback from engineers, customers and dealers around the world. Like and subscribe to our updates if this video was useful.
