Three Focal Points Relations of Laser Cutting Machine

-
It's important for laser cutting equipment operators to know the rules of laser beam focusing.Do you know three focal points relations of laser cutting machine?Now,let’s make a brief introduction for you.

1. Cutting focus on the workpiece

In this way we also become a negative focal length, because the cutting point is not located on the surface of the cutting material nor is it located inside the cutting material, but is located above the cutting material. This method is mainly used with cutting materials with high thickness. The reason why the focus of this approach is on the cutting material is mainly due to the need for thicker cuts of the thick plate, otherwise the oxygen delivered by the nozzle is extremely prone to cause insufficient and the cutting temperature is reduced. However, one of the disadvantages of this approach is that the cutting surface is rough and not very practical for high-precision cutting.

2. Cutting focus inside the workpiece

This method also becomes a positive focal length. When you need to cut the workpiece is stainless steel or aluminum steel plate commonly used cutting point in the workpiece inside the model. However, one disadvantage of this method is that, because the focal principle cuts the surface, the cutting width is relatively larger than the cutting point at the surface of the workpiece. At the same time, the required cutting airflow in this mode is large, the temperature is sufficient, and the cutting perforation time is slightly longer. So when you choose the workpiece material is mainly stainless steel or aluminum material hardness of the material used when the choice.

3. Cutting focus on the workpiece surface

This method also becomes 0 focal length, which is commonly used when SPC, SPH, SS41 and other workpieces are cut. When using, the focus of the cutter is selected to be close to the surface of the workpiece. In this mode, the smoothness of the upper and lower surfaces of the workpiece is not the same. The cutting surface that is close to the focal point is relatively smooth, while the lower surface that is distant from the cutting focal point appears rough. This mode should be based on the process requirements of the upper and lower surfaces in practical applications.

In summary, we use the laser cutting machine to process different workpieces and need to use different focus modes correspondingly, which can give full play to the performance advantages of the laser cutting machine.

  As one of the most important application field of sublimation printing , garment industrial plays an significant role in sublimation printing technology ’ s development. Why sublimation printing are used widely in garment industrial?    1. Good printing result   The garments printed by sublimation printing technology usually has beautiful patterns and vivid color. Besides, the layers of the patterns are rich and clear, so the images has a strong three-dimensional feeling.This is hard to achieve by other printing methods. What ’ s more, the sublimation printing can print the photographic pictures and paintings.    2. The garments are soft and the images have long service life   The biggest feature of sublimation transfer printing is the dye can be spread into the polyester or fiber, and the products feel very soft and comfortable. Because the sublimation ink has been dry in the transfer process, the life of the images are...

 Is DTG Printing Eco-friendly?    DTG printing is a more sustainable fashion business model than screen printing. Mainly because printing one-offs allows businesses to avoid overproduction and textile waste. With 92 million tons of textile going to waste in the fashion industry each year, a business model like this is a game-changer.     Plus, a lot of DTG printer manufacturers create advanced tech that’s made with sustainability in mind. For example, our partners with Sublistar whose printers produce almost zero wastewater and use less energy, lowering the carbon footprint.     What’s more, sublistar DTG printers use water-based vegan inks that they formulate, test, and produce in their own ink factories, maintaining the highest quality levels. The inks are non-hazardous, toxin-free, biodegradable, and contain no animal by-products.     Direct-to-garment printing is a hassle-free way to get the products ready for your customers. ...

What You Need Prepare For Dye Sublimation? Dye sublimation printer Printer is just one of the steps of the sublimation printing process . After printing, heat and press machine must be used to transfer an image onto fabric. As known, you can find various types of transfer printing machines with different features and advantages. Yet, the key point here is to invest in a machine according to your print requirements. To set an example, while small format print machines perfectly suit the needs of small production runs and garment printing, large format printers are generally considered a much better option for upholstery fabric, wide format ads, and promotional display products or high-volume productions. It is very important for users to pay attention to high-tech machine suppliers to choose the right printer. Such high technology covers following features: the printer software must keep color consumption at an optimum level, the software must deliver the best color management m...
