Ultrashort pulse laser equipment has been gradually shifting from the research laboratory to industrial micro processing.
Picosecond and FeiMiaoJi other pulse width enables the material to not be liquefied direct gasification.
Through cold ablation can be implemented to glass, metal, ceramic and polymer layered removal.
Watch industry is using the technology to carry on the fine carving, scanning galvanometer cutting and drilling of composite materials will not cause any heat affected zone (
HAZ）
, making the surface and edge quality is higher.
however, for some applications, the use of scanning galvanometer cold melt processing way to get the accuracy and cone Angle is not enough. Cone Angle is generated at the boundary of the cutting seam and partly because of the laser energy density ( The energy per unit area) Where there is lower, in part because materials redeposition. For these applications, using a fixed machining head, gas nozzle and high precision axis is of great advantage. However, the acceleration and speed of the shaft was trivial compared with the scanning galvanometer. Therefore, the introduction of laser heat in the fixed processing of application will be more. Even partial melting materials cannot be completely ruled out this kind of phenomenon. In spite of this, can still maintain the workpiece quality. With solid state laser and CO2 laser & other; Hot & throughout; Compared to laser cutting, ultrashort pulse to ensure that the introduction of heat can be controlled in time and space. So, still not thermal effects on the workpiece. With a fixed processing head USP laser micro cutting like a micron range of hot working.
compared with scanning galvanometer cold melt processing methods, if can correctly use fixed machining micro cutting head, can form a steeper Angle, at the same time maintain good edge quality. Optimization of the nozzle can provide processing gas, under the high pressure in addition to the material cutting seam. In addition to laser parameters, the nozzle geometry and location, as well as processing of gas type and pressure also significantly influence the cutting effect. Another important aspect is that the appropriate artifacts the development of the fixed clamp, at the same time support reliable fixed and free cutting material. To design the import processing, laser system must consider the location of the laser cut and export. When it comes to high precision, and the development of technology and quality control, requires the appropriate measuring equipment, will be able to reliably measure a few microns of tolerance and surface roughness values less than a micron.
all sorts of subsequent processing may be able to further improve the quality of workpiece. In the case of wire electrical discharge machining and micro milling, can consider to heat treatment to obtain target strength, hardness, or annealing material. In order to optimize the rough surface, if necessary, you can use some chemical mechanical processing method. Laser cutting workpiece, sometimes through electrochemical coating to achieve ideal surface. Watch industry is applying fixed optical micro cutting or drilling machining way one of the most important areas, such as ruby micro bearings, watch the handle or other elements.
in the machining process, usually we need to get a steep Angle of 90 degrees. Used for drilling holes, the so-called open hole drilling head can be done. When it comes to more complex geometrical shape of micro cutting, the method also has become more advantage of this type. From the point of view of thermal management, the machining method and the use of precision mechanical shaft fixed head of micro cutting process is similar. Some development work, however, still need to improve existing open hole drilling head, make them become more human, applicable to complex industrial micro cutting applications. An interesting and challenging to choose is the workholder compensation by a tilt Angle, especially for cutting out the artifacts.
laser equipment factory professional laser equipment manufacturer in China, products are laser printing machine, uv laser marking machine, laser cutting machine frame, and so on.
