CO2 lasers are some of the most popular types of lasers on the market today. They are used for various purposes, from laser cutting to laser welding. In this blog post, we will discuss the main features of CO2 lasers.
Let’s get started.
An Overview of CO2 Laser Machine
A CO₂ laser machine is a device that uses a laser to cut or engrave materials. It is the most versatile type of laser machine and can be used on various materials, including wood, plastic, glass, metal, and more.
CO₂ lasers are classified as either sealed tube or open-air machines. Sealed tube machines are hermetically sealed and have their own internal coolant system, while open-air machines use external cooling methods such as water-cooled chiller units.
The Main Structure of the Device
The C02 laser consists of mechanical, electrical, optical, peripheral, and sheet metal components.
1. Mechanical part
Power and transmission components make up the CO2 Laser Machine mechanical section. The interaction between the gear, belt, screw, transmission shaft, and coupler allows the motor to cause the laser head to rotate in accordance with the control input of the control software. The motor serves as the primary component of the power portion, while the guiding rail, belt, block, screw, gear, and transmission shaft serve as the primary components of the transmission part. Stepper and servo motors are the two primary types of motor.
The servo motor, which regulates the functioning of the mechanical parts in the servo system, is the primary distinction between the two. It is a tool that aids in the motor’s indirect motion and provides highly accurate feedback signals. The stepper motor is an electronic device with open-loop control which transforms electrical pulse impulses into linear or angular movement.
2. Electrical Part
The control system, driver, switching power supply, filter, relay, and switching make up most of the electrical portion. The device’s origin signal, the motor’s angle of spin and speed, the fact that the laser tube produces light, as well as the output light’s strength, are all variables that the control system may regulate. The electrical cabinet powers the control portion and the motor. Power converters supplies, relays, drivers, filters and control boards are located inside the electrical cabinet.
The controller power supply primarily drives the different axes. The board power supplies power the red light and the boards, and the filter filters the power supply intrusion band. The driver accepts the board. The pulse direction output manages the motor’s rotational speed and direction. The relay’s primary duties include controlling weak current, the laser energy supply’s power output, and the board card’s data handling and hardware control operations.
3. Optical section
The major components of the optical section are the laser power source, the laser tube, the focusing mirror, three mirrors, two mirror frames, the lasers head, and two holders for the laser tube. The laser tubes are split into 40w, 80w, 100w, 120w, and 150w categories based on power. The laser strength of various power laser tubes varies. The four primary categories of laser heads are miniature, hybrid, sliding rail, and conventional cutting heads.
The lenses are mainly concentrating mirrors and reflectors. The M series, hybrid cutting series and C/B series are the key features of the focusing lens. Molybdenum and silicon reflectors make up the majority of reflective mirrors.
4. Peripheral part
The major types of auxiliary equipment are water coolers, air pumps, fans and air compressors. The purpose of the peripheral component is to help the machine accomplish the tasks of the accessories. Similar to how a cooling water device works to cool the temperature of a laser tube, an air pump cools an object’s surface while keeping the focus lens clear. A fan removes smoke from a cutting operation to keep a workspace tidy.
5. Sheet metal part
The major components of the shell portion are the covers for various sheet metal pieces and the work surface, which accommodates the working component. The machine’s operating table is the functioning platform, and the treated objects are put on top. The countertops mainly consist of knife tops that can only be used to process rigid materials and are appropriate for cutting hard sheets.
The honeycomb mesa is ideal for treating reflective surfaces and flexible materials. A unique stainless steel lifting desk is suitable for engraving but not slicing, and an automated feeding net chain table is appropriate for treating flexible materials in batches.
