Background technology
Laser cutting has adaptability and flexibility widely.Compare with other conventional processing method, laser cutting has bigger adaptability.
At first, compare with other method for hot cutting, equally as the thermal cutting process, method for distinguishing can not act on a minimum zone as laser beam, and the result causes that otch is wide, the heat affected area is big and significantly work distortion.Laser energy cutting non-metal, other method for hot cutting then can not.
A large amount of manufactured partses are low, with short production cycle with stamping method cost.But it is very poor to the adaptability of the variation in the design, and new mould needs long-time design, the cost height, and centering, small-scale production, the characteristics of laser cutting will fully show.In addition, the tight layout of workpiece is convenient in the program control cutting of laser, saves material, and stamping then needs to reserve material around each work.
Generally speaking, it is die-cut than the big a lot of workpiece of die size that punch press is often wanted, and some work is also very complicated, and this just causes cutting edge and is many little conchoidal cutting edges, needs the trimming of preparation property processing for the second time.Drift can form than in the wide a lot of otch of laser cutting in addition, produces a large amount of iron filings.
Laser cutting is contactless flexibly as one, and the shape cutting instrument can begin tangential any direction cutting from any point of material.This point, sawing are difficult to accomplish.Generally, favourable electric spark and two kinds of methods of electrochemistry processing with galvano-cautery or fusion effect are used for the retrofit of stiff materials, and the otch roughness is better, but cutting speed is than the slow several magnitude of laser cutting speed.
Summary of the invention
