How Does a Laser Cutting Head for CNC Router Work?

The laser cutting head for CNC router is a high-precision cutting tool that uses a laser beam to cut and process materials. Its working principle and its main components are as follows:

1. Working Principle

Laser generation: The laser source (usually a carbon dioxide or fiber laser) inside the laser cutting head generates a highly concentrated and intense laser beam.
Laser transmission: The laser beam is transmitted to the cutting head through an optical fiber or a reflector system. The function of these reflectors and optical fibers is to stably guide the laser to the cutting area.
Focusing lens: After the laser beam reaches the laser cutting head for CNC router, it is focused to a small point through a focusing lens. This process greatly increases the density and energy of the beam, enabling effective cutting of the material.

2. Cutting Process

Material heating: The focused laser beam irradiates the surface of the material and quickly heats it to melt or vaporize. The energy of the laser is converted into heat, generating high temperatures to soften or volatilize the material.
Cutting gas: In many cutting applications, auxiliary gases (such as oxygen, nitrogen, or air) are ejected at the same time, which can not only help blow away the molten material, but also increase the effect of oxygen and speed up the cutting speed.
Laser movement: The laser cutting head for CNC router moves along the programmed path under CNC control to achieve cutting of the material.

3. Main Components

Laser source: The device responsible for generating the laser beam, which can be a CO2 laser, fiber laser or other type of laser.
Optical path system:
Reflector: Guides the laser beam from the laser to the cutting head.
Fiber (if fiber laser is used): Used to transmit the laser beam and can effectively guide the laser to the cutting head.
Focusing lens: Responsible for focusing the laser beam onto the surface of the material, usually made of high-quality optical materials that can withstand high temperatures and laser damage.
Auxiliary gas system: Including gas cylinders, regulating valves, nozzles, etc., responsible for providing the gas required for cutting, usually working synchronously with laser cutting.
Motion control system: The CNC control system is responsible for controlling the movement path, speed and cutting parameters of the cutting head to ensure accurate cutting according to the design drawings.

4. Advantages and Disadvantages of Laser Cutting Head for CNC Router

• Advantages:

High precision: Laser cutting can achieve very high cutting accuracy and adapt to the processing of complex shapes.
Small thermal impact: The heat-affected zone of laser cutting is small, which reduces material deformation and thermal damage.
High degree of automation: CNC systems can achieve automated cutting and reduce labor costs.

• Disadvantages:

Material limitations: Some materials (such as highly reflective metals) may be difficult to cut with lasers.
High equipment cost: The initial investment and maintenance costs of laser cutting equipment are generally high.

Summary

In short, the laser cutting head for CNC router achieves efficient cutting of a variety of materials by utilizing the high energy and high focusing characteristics of the laser, and is widely used in various fields such as manufacturing, automobiles, and aviation.
