How Choose to cutting quality of a fiber laser cutting machine ?

When you need to cut intricate shapes out of sheet metal or acrylic, there is often no better tool than a laser cutter. This cutting technology uses a high-powered laser to cut materials quickly and with incredible precision. Not only do laser cutters make clean cuts in a variety of materials, but they can also engrave patterns on surfaces. Fiber laser cutting machines are a popular type of CNC laser cutting machine. In this article, we will discuss how to choose the cut quality of a fiber laser cutter.

1. The influence of focus position adjustment on the cutting quality of fiber laser cutting machine

2. Influence of cutting procedure on the cutting quality of fiber laser cutting machine

3. The impact of cutting speed on the cutting quality of fiber laser cutting machine

4. Influence of laser output power on cutting quality of fiber laser cutting machine

5. The impact of layout planning on the cutting quality of fiber laser cutting machine

1. The influence of focus position adjustment on the cutting quality of fiber laser cutting machine

The choice of lens focal length is a critical decision, because the laser power density has a great impact on the cutting speed. After the laser beam is focused, the spot size is inversely proportional to the focal length of the lens. The spot size after focusing of a short focal length lens is very small and the power density at the focal point is very high, which is very favorable for material cutting. However, its disadvantage is that the depth of focus is very short, the adjustment margin is small, generally applicable to the high-speed cutting of thin materials. As long as the long focal length lens has sufficient power density, it is more suitable for cutting thick workpieces because of its large depth of focus. Keeping the relative positions of the focal point and the workpiece constant throughout the cutting process is a key requirement for obtaining stable cutting quality. Sometimes, poor cooling during operation can cause the lens to heat up, thus changing the focal length, which requires timely adjustment of the focal position. Better focusing enables the fiber laser cutting machine to cut narrower slits, higher efficiency, and achieve better cutting results with faster cutting speed.

2. Influence of cutting procedure on the cutting quality of fiber laser cutting machine

Considering the technical requirements of the product, it is crucial to choose the right cutting program. In daily production and processing, we may need to use fiber laser cutting machine to cut different patterns, which requires the use of various cutting methods. In order to produce high quality products quickly, our operators must set the appropriate cutting method according to various cutting techniques.

3. The impact of cutting speed on the cutting quality of fiber laser cutting machine

Fiber laser cutting machine cutting speed has a great impact on the cutting quality, the appropriate cutting speed will make the cutting surface appears smooth and the lower part of no slag. Cutting speed is too fast, will lead to the material can not cut through, causing sparks splash, the lower part of the slag, and even burn the lens. Cutting speed is too slow, it is easy to cause the material over-melting, the slit becomes wider, the heat-affected zone increases, and even cause over-melting of the workpiece.

4. Influence of laser output power on cutting quality of fiber laser cutting machine

The size of the laser power and the caliber of the mode can have a significant impact on the cutting of a continuous wave output fiber laser source. In practice, larger power settings are often used to achieve faster cutting speeds or to cut thicker materials. However, the beam pattern (the way the beam energy is distributed across the entire cross-section) can also have a significant effect on cutting and tends to get worse as the output power increases. The beam pattern will change throughout the life of the laser.

5. The impact of layout planning on the cutting quality of fiber laser cutting machine

Under the premise of quality assurance, a good layout plan must be developed. When we receive raw materials, the first thing to consider is how to shorten the cutting route, avoid repeated cutting and improve cutting efficiency. Cutting speed, focusing position, laser output power, cutting technology and layout planning are the five key criteria, although the impact of these parameters on fiber laser cutting machines is very complex. If the cut quality is found to be significantly poor throughout the entire cutting process, all of the above parameters must first be verified and changed immediately.
