The radium shoots is one of 20th century greatest inventions, the significant technical achievement which is which with the thermonuclear technology, the Semiconductor Technology, the electronic computer and the aerospace technology compares favorably with attracts worldwide attention.
the radium shoots has the high directing property, the high monochromaticity and the high coherence characteristic, in domain applications and so on the industry, agriculture, biology, trade, national defense is widespread.In the 90s , item of brand-new radium shoots the application technology - radium to shoot hits the sign technology, shoots the light beam illumination work piece surface using the radium, causes the work piece surface instantaneous to melt the melt even to gasify, thus forms permanent marks and so on the writing, design in the surface.Because the radium shoots shines to the work piece surface is partial, the processing spot temperature is extremely high, to non-illumination spot influence really micro, therefore the work piece heat-affected zone is very small, the work piece does not have the distortion basically, does not have loses.
In the industry, in domains and so on the decoration industry, the radium shoots hits the sign machine versatility, the effect and the stability is good.Through controls two to inspire the mirror deflection ﹙to control X and the Y axis separately﹚, shoots the path of rays to the radium to carry on the reflection, thus scans each kind of design in the goal surface.With the traditional machine engraving, chemistry corrode, ways and so on silk-screen printing, printing ink series printing compare, the radium shoots hits the sign to have permanently without the pollution,..續..

In the industry, in domain and so on the decoration industry, the radium shoots hits the sign machine versatility, the effect and the stability is good. Through controls two to inspire the mirror deflection ﹙ separately to control X and the Y axis ﹚, shoots the path of rays to the radium to carry on the reflection, thus scans each kind of design in the goal surface. With the traditional machine engraving, chemistry corrode, way and so on silk-screen printing, printing ink series printing compares, whether there is does the radium shoot hits the sign to have pollutes, the mark permanently, the cost low, the quality good, the flexibility high, hits the sign speed quickly, the performance is stable, merit and so on easy computer control, moreover may individually distinguish the serial number to the mass production work piece implementation product, bar code sign on product, thus effectively realizes the production working procedure control, the quality control and the product guards against falsely, enhances the product scale, the enhancement product competitive ability. Now widely has applied to each kind of precision product in the and so on instrument, automobile fitting, electronic primary device, clock and watch trademark, the batch number, the manufacture date, the bar code.
This article shot to the radium hits the sign system to carry on the comprehensive discussion, and emphatically introduced the radium shot hits the sign system, the optical system research and the control method, and carried on in the understanding computer lattice memory foundation develops the algorithm design.

Laser is the 20th century one of the greatest inventions, with the thermonuclear technology, semiconductor technology, electronic and computer technology and aerospace comparable to a world of the major scientific and technological achievements. Laser with high directional, high monochrome and high coherence of the characteristics of the industrial, agricultural, biological, commercial, widely used in areas such as national defense. In the 1990s, a new application of laser technology - laser marking technology, using laser beam irradiation surface, the surface instantaneous melt even gasification, which formed on the surface in the text, pictorial and other permanent marker. As laser irradiation to the workpiece surface is partial, high temperature processing site to the non-irradiated sites have little effect, the heat affected zone of the workpiece small workpiece without basic deformation without loss. in the industrial and decorative industry, and other fields, laser marking machine a wide range of uses, good effect and stability. By controlling two galvanometer deflection (X and Y-axis control), the laser light path for reflection, resulting in a variety of target surface scanning pattern. And the traditional mechanical sculpture, chemical etching, screen printing, ink printing method compared to laser marking a clean, permanent markers, low cost, good quality, high flexibility, marking fast, stable performance, easy computer control advantages, but also can be mass-produced parts for a single product identification number, the bar code standard in the products, so as to effectively control production processes, quality control and product security, upgrade products, and enhance the competitiveness of products . It is now widely used in all kinds of sophisticated equipment, auto parts, electronic components, watches and clocks, and other products on the trademark, batch number, date of the factory, on the bar code.
