Part I: Laser cutting Machine Basics

It is very important to understand the basic components and working principle of a laser cutting machine, which will help you better choose the right machine and build a solid foundation for subsequent learning.

 

1. What is a laser cutter?
A laser cutting machine is a device that uses laser technology to cut, engrave or mark objects. It works by focusing a powerful laser beam on a very small area of material, where high heat causes the material to evaporate or change color, resulting in a detailed pattern or text.

 

2. Types of laser cutting machines
CO2 laser cutting Machine: This is the most common type and is suitable for non-metallic materials such as wood, plastic, paper, glass, etc.

Fiber laser engravers: mainly for metals and plastics, suitable for applications requiring high precision marking.

 

Other types, such as diode lasers, have their own specific applications and material adaptability.

 

3. Introduction of main components
Laser source: the component that generates laser beam, is the heart of the whole machine.

Control system: control the movement of the laser head and laser output, usually equipped with corresponding software.

Table: The platform on which the material is placed, which may include fixtures or adjustment mechanisms. For example, a honeycomb panel is usually included.

Laser Head: Contains the focusing lens and mirrors to direct and focus the laser beam.

Cooling System: Used to cool the laser source and ensure stable machine operation.

 

4. Safety Guidelines and Precautions
Safety is the primary concern when operating a laser engraver. The laser beam is extremely powerful and improper use can cause serious injury or fire.
Personal Protective Equipment (PPE): Always wear protective eyewear and avoid looking directly into the laser beam.

 

Pre-Operation Inspection: Make sure all parts are functioning properly and show no signs of looseness or damage.

 

Know Your Materials: Some materials may produce toxic fumes when cut by the laser, make sure you understand the nature of the materials you are using and take appropriate ventilation measures.

 

Training and Guidelines: Make sure you have fully understood the machine's instructions and safety guidelines before operating it.

 

After understanding these basics, you will be more than ready to begin your laser cutting journey. Remember, every step of the way is about making sure you can use your laser engraver safely and effectively. In the next section, we'll discuss how to prepare to start your first laser cutting project.
