Cutting quality of the ZuoLong mechanical action: how to judge? Basically see the six principles

Roughness. Cutting section will form the vertical grain, grain depth determines the cutting surface roughness, the lighter the grain, the cutting section is more smooth. Roughness is not only affect the appearance of the edge, but also affect the friction characteristics, in most cases, the need to reduce the roughness as far as possible, so the more shallow, grain, the higher the cutting quality. Verticality. How the thickness of the sheet metal for more than 10 mm, the cutting edge of vertical degree is very important. Away from the focus, beam divergence, according to the location of the focus, cutting towards wider at the top or bottom. Cutting edge what percentage deviation from vertical line mm, margin is vertical, the higher the cutting quality. Cutting width. Notch width in general will not affect the cutting quality, only the outline of special precision is formed within the parts, the cutting width is important, because the cutting width determines the outline minimum Canon, when the plate thickness increases, the cutting width also will increase. So want to ensure that the same precision, no matter how hard it is incision width, the workpiece in cutting machine processing area should be constant. Grain. High-speed cutting plate, molten metal will not appear in the vertical beam at the bottom of the incision, may after a bunch of partial place. As a result, the curved lines formed in the cutting edge, texture closely follow moving beam, in order to fix this problem, at the end of cutting processing to reduce the feed rate, can greatly eliminate grain line. Burr. Burr formation of decision, a very important influence factors of cutting quality, because of the burr removal need extra workload, so the burr can serious and how much is the intuitive judgment of the quality of the cutting. Material deposition. Before cutting machine at the start of piercing in workpiece surface with a layer of special liquid oil. Cutting process, because of the gasification and various materials need not, the customer with the wind except incision, but the upward or downward discharge will be formed in the surface deposition. Sag and corrosion. Sag and have an adverse effect on the surface of the cutting edge of corrosion, affect the appearance. They appear in general should avoid cutting error. Heat affected zone. Cutting, along the area around the incision is heated. At the same time, the structure change of the metal. For example, some metal hardening will happen. Heat affected area refers to the depth of the internal structure change in the region. Out of shape. If cut sharply heating parts, it will be out of shape. This is especially important in the fine processing, because the outline and the connection piece is usually only a few millimeters wide ten points. Control power and the use of short pulse can reduce parts heat, avoid deformation
