Fiber laser cutting machines are a popular tool used in industry due to their high precision and speed of cutting. In this article, we’ll introduce the composition and structure of fiber laser cutting machines, as well as common power and cutting material types and how to select the correct power machine.
Composition and Structure
A fiber laser cutting machine consists of the following components:
- A generator/resonator
- Ceramic Optics or Focus Lens
- X/Y motion lifter
- A Cutting Head
- A Control System
The generator/resonator is the main component of the entire system – it delivers the power signal with a given frequency into a tube containing a rare gas and vapor. This signal is then amplified until it reaches the focusing optics.
The ceramic optics or focus lens are responsible for directing the final laser stream along the axis of the cutting process.
The X/Y motion lifter is the mechanism that allows the cutting head to move along two axes. It consists of servo motors, DC motors, stepper motors, and linear motors with connecting rails and slides.
The cutting head consists of the nozzle and protection window. Its purpose is to direct the high-intensity laser beam towards the focuses lens to the cutting point.
The control system is the “brain” of the entire cutting machine – its job is to manage the position of the cutting path, speed and power settings, and the monitoring of the parameters during the cutting process.
Common Power & Material Types
Fiber laser cutting machines come with different power configurations. Common power types are 1000W, 2000W and 4000W. For materials, aluminum, stainless steel and other metals are quite often cut using these machines.
Selecting the Correct Power Machine
When selecting a machine for your own application, you must consider several factors, including materials and thickness to be processed. Generally speaking, for thinner materials, a smaller configuration set up is more appropriate; for thicker materials, a higher power setting is preferable. Once you know the materials and thickness to be handled, you can make an informed decision regarding the most appropriate configuration for your specific needs.
