Ready to buy a fiber laser cutting machine but worried about how to use it? The operation of the fiber optic cutting machine is very simple. The following introduces the operation steps and solutions to common problems to help you understand quickly.

 


Laser cutting machine operating steps




1. Understanding the Components of Your Fiber Laser Cutting Machine


A fiber laser cutting machine consists of several key components:

· Laser Source: Generates the high-intensity laser beam used for cutting.

· Cutting Head: Focuses the laser beam and directs it onto the material.

· Control System: An advanced software interface that commands the machine movements and settings based on the design files.

· Bed: The surface where materials are laid out for cutting.

· Assist Gas System: Uses gases like oxygen, nitrogen, or air to aid the cutting process, depending on material type.


2. Installation and Setup


Installation Environment: Place your machine in a stable, low-dust area to cut down on cleaning and maintain steady temperatures to keep the laser sharp.

Power Connection: For power, use a supply that fits the maker's specs to avoid surges that could harm your equipment.


3. Pre-Operation Preparation


· Material Placement: Use clamps or other mechanisms to secure the material to the bed to prevent movements during cutting.

· Software Setup: Load design files into the control software. This is typically done via CAD (Computer-Aided Design) files that specify the dimensions and shapes of the cuts.


4. Setting Cutting Parameters


· Cutting Speed and Power: The speed at which the cutting head moves and the power of the laser are critical. Thicker materials must lower speeds and higher power settings.

· Focus Change: The laser should be precisely focused on the surface of the material, adjusted manually or automatically depending on your machine model.

· Choosing Assist Gas and Pressure: Different materials must have different gases. For instance, nitrogen is often used for metals to prevent oxidation at the cut edges.


5. Starting the Cutting Process


· Performing a Test Cut: Always perform a small test on a piece of scrap material to verify the settings. Adjust the parameters if the test cut shows any signs of burning or incomplete cuts.

·Monitor: Watch the first few cuts closely to make sure the material is being cut. If there is a fire or excessive smoke, this may indicate an incorrect setting.


6. Routine Maintenance and Troubleshooting


· Daily Checks: Inspect lenses and mirrors for dirt or damage each day. Clean them with a specific cleaning solution and lint-free cloths designed for optical components.

Monthly maintenance: Check and tighten all mechanical connections. If consumable items such as nozzles and protective windows show signs of wear, be sure to replace them promptly.

· Common Troubleshooting: If cuts are inconsistent, check laser focus, gas pressure, and if the material is flat and properly supported.


7. Safe Operation


· Training: Ensure all operators complete a safety course specific to laser operation. Understand and respect the machine's safety features such as interlocks and emergency stop buttons.

· Protective Measures: Always use protective gear, including laser-safe goggles and fire-resistant gloves.

 

 

Frequently Asked Questions about the Metal Laser Cutting Process



1. The laser does not cut through the material completely


· Solution: Check and adjust the laser power and cutting speed. Ensure the focus point of the laser is correctly set for the type of material and thickness you are working with. Also, verify that the assist gas pressure is adequate.


2. Too much dross accumulates at the bottom of the cut


· Solution: This is often due to too low cutting speed or too high laser power. Adjust these parameters incrementally. Additionally, check if the right type of assist gas is used and if the gas pressure needs to change.


3. Burn marks around the cut edges


· Solution: Burn marks can be a sign of too high power or too slow speed. Adjust both to find a balance that minimizes burns. Ensure that the assist gas flow is enough, as it helps to cool the material and eject debris.


4. The edges of the cut are rough or irregular


· Solution: Besides checking the laser power and cutting speed, ensure that the nozzle is aligned correctly and that there is no blockage. Also, ensure the material is properly supported and flat on the cutting bed.


5. The machine stops mid-operation or displays error codes


· Solution: First, check the control software for error messages that can guide you to the issue. Ensure all connections are secure, and the power supply is stable. Regular maintenance checks can preempt these issues by catching them early.


6. The machine does not follow the programmed cutting paths accurately


· Solution: This could be due to a calibration issue. Re-calibrate the machine according to the manufacturer’s guidelines. Also, check the condition of the guide rails and lead screws, as wear and tear can affect precision.


7. Consumables like lenses and nozzles wear out faster than expected


· Solution: Ensure you are using the correct type of consumables for your materials and cutting parameters. Also, regular cleaning and proper installation can extend their life.



Through the above steps, I hope it will help you use the fiber laser cutting machine more scientifically. Although the above steps are short, you need to practice continuously in actual operation to become familiar with every detail. Remember, continuous learning and practice are the keys to mastering any new technology.
