Whether it is washing machine, voltage cooker, rice cooker and so on, household appliances closely related to our life and diet are playing an increasingly important role in the home. And these electrical appliances will involve stainless steel material.

　　在常用的电器产品中，激光切割机主要应用于洗衣机、冰箱、空调等产品的外壳金属件、塑料配件、金属零件(金属板材的零件几乎占所有零件的30%以上)的钻孔、切割。比如，可以对对薄钢板零件进行切割加工，进行空调金属配件、金属外罩切割，进行冰箱底部或背部散热网板切割、打孔，抽油烟机金属导烟板切割等。

　　In the common electrical products, laser cutting machine is mainly used for drilling and cutting of me
tal parts, plastic parts and metal parts (metal sheet parts account for more than 30% of all parts) of the shell of washing machine, refrigerator, air conditioner and other products. For example, thin steel plate parts can be cut, air-conditioning metal parts, metal cover cutting, refrigerator bottom or back heat dissipation mesh plate cutting, drilling, smoke hood metal guide plate cutting, etc.

　　传统的不锈钢切削工艺存在刀具磨损，加工效率低，且易产生毛刺、表面粗糙、变形等问题。而与之相对的，激光切割工艺优点多多，成为不锈钢加工企业的共同选择。

　　Traditional stainless steel cutting technology has many problems, such as tool wear, low processing efficiency, burr, rough surface, deformation and so on. In contrast, laser cutting technology has many advantages, and has become a common choice for stainless steel processing enterprises.

　　1无加工应力，工件不变形

　　1. No working stress, no distortion of workpiece

　　采用激光切割设备切割，不受材料的硬度的影响，这是由于激光的特性决定的，是传统设备没有办法比拟的优点，激光切割可对钢板、不锈钢、铝合金、硬质合金板进行无变形切割。

　　Laser cutting equipment is not affected by the hardness of the material, which is determined by the characteristics of the laser. It is an advantage that traditional equipment can not match. Laser cutting can cut steel plate, stainless steel, aluminum alloy and cemented carbide plate without deformation.

　　2不用二次处理，加工效率高

　　2. No secondary treatment, high processing efficiency

　　采用激光切割设备加工不锈钢板，采用的是无接触式加工方式，不会影响工件的变形，也不会影响下一道工序的进行，且通过激光切割处理后不用二次处理，切割表面光滑。

　　Laser cutting equipment is used to process stainless steel plate, which adopts non-contact processing mode, will not affect the deformation of the workpiece, nor will it affect the next process, and after laser cutting, no secondary treatment is needed, and the cutting surface is smooth.

　　3定位精度高，切割表面光滑

　　3. High positioning accuracy and smooth cutting surface

　　激光束聚焦成很小的光点，使焦点处达到很高的功率密度材料很快加热气化程度，蒸发形成孔洞，光束质量高，定位精度高，因此切割的精度也高。

　　Laser beams focus into very small light spots, so that materials with high power density at the focus are heated to gasification degree quickly, and evaporation forms holes. The quality of laser beams is high, the positioning accuracy is high, so the cutting accuracy is also high.

　　4无刀具磨损，维护成本低

　　No tool wear, low maintenance cost

　　采用激光切割机切割不锈钢没有损耗，切光电转换率高，加工成本也是低廉，采用光纤激光切割机也是免维护。

　　Laser cutting machine is used to cut stainless steel without loss, high photoelectric conversion rate, low processing cost, and the use of fiber laser cutting machine is maintenance-free.

　　激光切割机除了具有传统下料、切角、开孔和修边等工艺不可比拟的灵活性和加工精度，还可以实现定制化、个性化高批量生产。由于激光切割机采用的是“无接触加工”，无需模具制作和成本，加工图形由软件制作，图案多样，因此能有效地提高产品质量、降低生产成本，并贴合企业生产定制化、精细化需求。

　　Laser cutting machine not only has the incomparable flexibility and processing precision of traditional cutting, cutting angle, opening and trimming technology, but also can realize customized, personalized and high-volume production. Because the laser cutting machine uses "non-contact processing" without the need of die making and cost, the processing graphics are made by software and the patterns are diverse, so it can effectively improve product quality, reduce production costs, and meet the needs of customization and refinement of enterprise production.

　　目前激光切割机在家电制造行业的渗透率还远远不够，但随着现代科技的发展，家电行业的传统加工工艺不断转型升级，激光切割无论是提高加工质量，还是优化产品外观方面，竞争力逐渐凸显，其重要性已经逐步为制造商所认识，可以断定，激光技术在家电行业中的应用将越来越广泛，其发展潜力与市场机遇将不可估量。

　　At present, the penetration rate of laser cutting machine in household appliances manufacturing industry is far from enough, but with the development of modern science and technology, the traditional processing technology of household appliances industry is constantly transforming and upgrading. Whether laser cutting improves the processing quality or optimizes the appearance of products, the competitiveness is gradually highlighted. Its importance has been gradually recognized by manufacturers. It can be concluded that laser technology in household appliances industry is becoming more and more important. Its application will be more and more extensive, and its development potential and market opportunities will be immeasurable.
