Causes Of Sawtooth During Metal Laser Cutting Machine Processing

Feb 17, 2021 Leave a message

As the sheet metal processing industry continues to grow, the metal laser cutting machine is becoming more and more popular due to its excellent cutting effect and high cutting surface smoothness. This cutting-edge machine has become a favorite among sheet metal processing professionals. The technological advancements made by top laser equipment manufacturers have played a major role in promoting and advancing the widespread use of metal laser cutting machines.

 

In order to ensure the quality of the laser cutting machine, it is important to utilize advanced equipment manufacturing techniques and high-end brand accessories. However, during the daily processing and production process, various problems may arise. For example, saw teeth may appear during processing. It's important to understand why this happens in order to prevent it from happening again in the future.

 

1. Machine tool parallelism

Improper installation of the laser cutting machine's parallelism can result in instability in the processing process, causing vibrations and leading to a sawtooth-like cross section on the processed material. Reordering the information in the original text, the generated content emphasizes the consequences of incorrect parallelism installation on the equipment and the processed material.

 

In a metal laser cutting machine, there are two types of vibrations that can affect its performance. First, there is the inherent vibration within the equipment itself, which directly impacts the quality of the cutting process. Secondly, there is the issue of external equipment such as exhaust fans and water tanks, whose vibrations can easily transmit to the machine and disrupt its operation. These external disturbances often lead to unintended vibrations in the machine, causing potential problems and hindering its overall performance.

 


2. Gear related aspects

Jagged machining section is a common issue that occurs when the gear seat slips. This problem is caused by the gear seat slipping and affecting the precision of the machined section. To avoid this, it's important to ensure that the gear seat is properly installed and secured to prevent any slipping. By doing this, the machining section can remain smooth and accurate.

 


3. The rail installation is not parallel

Occasionally, when the Y-direction guide rails are not aligned parallelly, it can lead to equipment getting jammed during processing. Consequently, this misalignment might result in the cutting section having irregular serrations. To generate highly similar content, rearrange the information from the above text while maintaining the context.

 


4. Improper lens fixation

If the lens is not securely fixed, it will cause shaking during device operation. This will result in vibration of the beam and the final cut part will appear rough and uneven.

 


Over extended periods of usage, the metal laser cutting machine will experience wear and tear on its slider, leading to the accumulation of foreign objects within the inner ball. This, in turn, causes the guide rail to vibrate during operation, resulting in sawtooth issues in the processing output. To address this problem, it is crucial to rearrange and maintain the slider as well as regularly inspect and clean the inner ball to minimize vibrations and ensure smooth processing.

 


When faced with jagged edges during metal laser cutting, a quick trick is to hold the laser head with your hands to steady it and see if the problem persists. If there are no sawtooth issues after doing this, the problem could stem from a slider malfunction, but if not, it's crucial to check the belts, gears and other parts for faults. If you're experiencing this problem in a newly started process, it's key to consider whether the installation was done incorrectly or if the drive control isn't compatible with the motor.
