Inspect and replace consumables such as nozzles and protective lenses when necessary. Monitor and maintain the cooling system to prevent overheating. Keep the machine's software up-to-date for access to the latest features and improvements.

What is a Laser Cutting Machine?


Before delving into maintenance, let's first understand what a fiber laser cutting machine is. A laser cutting machine uses a high-powered laser beam to cut, engrave, or mark various materials such as metals, plastics, and wood. Fibre laser cutting machines are renowned for their speed, precision, and versatility, making them a popular choice in various industries like manufacturing, automotive, aerospace, and more.

Working Principles of Fibre Laser Cutting Machines

Fiber laser cutting machines operate on the principle of stimulated emission, wherein light energy is amplified and focused to cut through materials. The working principle can be summarised in the following steps:

1. Laser Generation

A seed laser produces a low-power laser beam.

2. Amplification

The beam is amplified as it passes through a fiber optic cable with rare-earth elements like erbium, ytterbium, or neodymium.

3. Beam Focusing

The amplified laser beam is precisely focused on the material to be cut using a lens.

4. Material Cutting

The intense energy of the focused laser beam rapidly heats up and vaporizes the material, resulting in a clean and precise cut.
