随着高精密加工需求的增加，相关的精密加工技术也随之快速发展，其中精密激光切割机在市场上也获得了越来越多的认可。

以薄板为主的精密激光切割机加工技术，加工精度高、速度快、切口光滑平整，一般无需后续加工;切割热影响区小，板材变形小;加工精度高、重复性好，不损伤材料表面。目前精密加工的应用行业越来越多，PCB板切割、微电子线路模板精密切割、眼镜行业、首饰行业。

激光精密加工有如下显著特点：

1. 范围广泛：激光精密加工的对象范围很宽，包括几乎所有的金属材料和非金属材料;适于材料的烧结、打孔、打标、切割、焊接、表面改性和化学气相沉积等。而电解加工只能加工导电材料，光化学加工只适用于易腐蚀材料，等离子加工难以加工某些高熔点的材料。

2. 准确细致：激光束可以聚焦到很小的尺寸，因而特别适合于精密加工。激光精密加工质量的影响因素少，加工精度高，在一般情况下均优于其它传统的加工方法。

3. 高速快捷：从加工周期来看，电火花加工的工具电极精度要求高、损耗大，加工周期较长;电解加工的加工型腔、型面的阴极模设计工作量大，制造周期亦很长;光化学加工工序复杂;而激光精密加工操作简单，切缝宽度方便调控，可立即根据电脑输出的图样进行高速雕刻和切割、加工速度快，加工周期比其它方法均要短。

4. 安全可靠：激光精密加工属于非接触加工，不会对材料造成机械挤压或机械应力;相对于电火花加工、等离子弧加工，其热影响区和变形很小，因而能加工十分微小的零部件。

5. 成本低廉：不受加工数量的限制，对于小批量加工服务，激光加工更加便宜。对于大件产品的加工，大件产品的模具制造费用很高，激光加工不需任何模具制造，而且激光加工完全避免材料冲剪时形成的塌边，可以大幅度地降低企业的生产成本提高产品的档次。

6. 切割缝细小：激光切割的割缝一般在0.1-0.2mm。

7. 切割面光滑：激光切割的切割面无毛刺。

8. 热变形小：激光加工的激光割缝细、速度快、能量集中，因此传到被切割材料上的热量小，引起材料的变形也非常小。

9. 节省材料：激光加工采用电脑编程，可以把不同形状的产品进行材料的套裁，比较大限度地提高材料的利用率，大大降低了企业材料成本。

10. 非常适合新产品的开发：一旦产品图纸形成后，马上可以进行激光加工，你可以在比较短的时间内得到新产品的实物。

总的来说，激光精密加工技术比传统加工方法有许多优越性，其应用前景十分广阔。

With the increasing demand of high precision machining, the relevant precision machining technology has also developed rapidly, among which the precision laser cutting machine has gained more and more recognition in the market.

Precision laser cutting machine based on thin plate processing technology, high precision, fast speed, smooth cut, generally no need for follow-up processing; Cutting heat affected area is small, plate deformation is small; High machining accuracy, good repeatability, no damage to the surface of the material. At present, the application of precision machining industry is increasing, PCB board cutting, microelectronic circuit template precision cutting, glasses industry, jewelry industry.

Laser precision machining has the following notable features:

1. Wide range: laser precision machining has a wide range of objects, including almost all metal materials and non-metallic materials; Suitable for sintering, punching, marking, cutting, welding, surface modification and chemical vapor deposition. While electrochemical processing can only process conductive materials, photochemical processing is only applicable to corrosion-prone materials, and plasma processing is difficult to process some materials with high melting point.

2. Precise and meticulous: laser beam can be focused to a very small size, so it is especially suitable for precision machining. In general, laser precision machining is superior to other traditional machining methods because of its low quality and high precision.

3. High speed and high speed: in terms of machining cycle, edm tool electrode requires high precision, high loss and long machining cycle; The design work of cathode mould of machining cavity and surface in electrochemical machining is large and the manufacturing cycle is long. Photochemical processing process is complex; However, laser precision machining is simple to operate and convenient to adjust the width of cutting seam, which can be used for high-speed carving and cutting according to the pattern output by computer. The processing speed is fast and the processing cycle is shorter than other methods.

4. Safe and reliable: laser precision machining is non-contact processing, which will not cause mechanical extrusion or mechanical stress on materials; Compared with edm and plasma arc machining, its thermal impact zone and deformation is very small, so it can process very small parts.

5. Low cost: it is not limited by the quantity of processing. For small batch processing service, laser processing is cheaper. For the processing of large products, the mold manufacturing cost of large products is very high, laser processing does not need any mold manufacturing, and laser processing completely avoids the edge collapse caused by material punching and shearing, which can greatly reduce the production cost of enterprises and improve the product grade.

6. Small cutting seam: the laser cutting slit is generally 0.1-0.2mm.

7. Smooth cutting surface: no burr on the cutting surface of laser cutting.

8. Small thermal deformation: the laser cutting seam of laser processing is thin, fast and concentrated, so the heat transferred to the cut material is small, and the deformation caused by the material is very small.

9. Material saving: laser processing adopts computer programming, which can be used to cut materials of products of different shapes to maximize the utilization rate of materials and greatly reduce the material cost of enterprises.

10. Very suitable for the development of new products: once the product drawings are formed, you can immediately carry out laser processing, and you can get the new product in the shortest time.

In general, laser precision machining technology has many advantages over traditional machining methods, and its application prospect is very broad.
