Laser cutting and the section will form the vertical grain, grain depth determines the cutting surface coarse degree, the more shallow grain, and cross section is more smooth.
Heat affected area refers to the depth of the internal structure change in the region.
Cutting process, because not gasification and various materials customers use the wind except incision, but the upward or downward discharge will be formed in the surface deposition.
Sag and erosion have an adverse effect on the surface of the cutting edge, affect the appearance.
If cutting makes sharp heating parts, it will be out of shape.
The area around the laser cutting, along the incision is heated.
burr. Incision width in general will not affect the cutting quality, only at the outline of the special precision is formed within the components, cutting width just have important influence, this is because the cutting width determines the contour of the small Canon, when the sheet thickness increases, the cutting width also will increase. Coarse degree not only affects the appearance of the edge, but also affect the friction characteristics, in most cases, the need to reduce coarse degree as far as possible, so the more shallow, grain, the higher the cutting quality.
verticality. Laser cutting machine at the start of piercing in workpiece surface with a layer of oil before the special liquid. How the thickness of the sheet metal for more than 10 mm, the cutting edge of vertical degree is very important.
pattern of the laser cutting machine. What percentage deviation from vertical line mm cutting edge, the edge is vertical, the higher the cutting quality. As a result, the curved lines formed in the cutting edge, texture firmly follow the moving laser beam, in order to fix this topic, at the end of cutting processing to reduce the feed rate, can greatly eliminate grain line. They flush in general should avoid cutting error. For example, some metal hardening will happen.
laser cutter material deposition. Burr formation when determining the quality of laser cutting is a very important influence factors, due to the burr removal need extra workload, so serious and how much is the amount of burr can directly determine the quality of the cutting.
deformation of laser cutting machine. Control of laser power and the use of short laser pulse can reduce parts heat, avoid deformation.
sag and erosion. At the same time, the structure change of the metal. After the focus, the laser beam divergence, according to the location of the focus, cutting towards wider at the top or bottom.
laser cutting machine coarse degree. So want to ensure equality and high precision, no matter how big notch width, artifacts in processing areas of the laser cutting machine should be constant. High-speed cutting plate, molten metal won't flush in vertical laser beam at the bottom of the incision, may in the laser beam after partial.
heat affected zone.
the cutting width. 。 This is especially important in the fine processing, the contour and the connection piece here usually only 10 points a few millimeters wide.
