Application trends and development trends of Mitsubishi CO2 laser cutting machine in the world


Nagoya Manufacturing Co., Ltd. Laser Systems Department GOS G Dr. Jin Gangyou



At present, CO 2 laser cutting technology has been rapidly developed around the world. From the sales situation of Mitsubishi CO 2 laser cutting machine, in 2006, about 4,000 new laser processing machines for metal cutting with output power of 1 kW or more were sold worldwide. There are about 1,600 in Europe, about 1,500 in Asia, and about 900 in the United States. The annual growth rate of sales has exceeded 10%, making the status of laser processing machines for cutting machines increasing year by year. In the past, laser cutting machines were considered to be suitable for many varieties and small quantities. However, laser processing machines do not require traditional molds and have high processing quality. In this respect, they are superior to punching machines and have improved high-speed cutting performance. The unmanned operation of the shelves has made the popularity of laser processing machines begin to accelerate.

Laser cutting is suitable for all areas requiring sheet metal processing, and has been continuously developed in the processing of metal parts, such as automotive parts, motor parts, elevator parts, agricultural machinery, construction machinery, various basic equipment parts and aviation. Machine parts and so on are the specific industries that introduce laser processing machines. Since the first CO 2 laser cutting machine was introduced in 1979, Mitsubishi Electric has been committed to the research and development of the high output power of the oscillator, the high performance of numerical control, and the high-speed technology of the processing machine. Export Mitsubishi laser processing machine.

The corresponding advantages of after-sales service. Since the product components of the Mitsubishi CO 2 laser processing machine are made by Mitsubishi Electric, the corresponding ability of after-sales service has obvious advantages. In the same factory of the same company, the production from the vibration damper to the processing machine, control device, and automatic program device can be reflected on the product in a short time when the user has improved the requirements.

According to the application of Mitsubishi Electric's CO 2 laser cutting technology in key areas, and looking forward to the development trend of CO 2 laser cutting technology, we believe that CO 2 laser is the most energy-efficient, pulse-vibrating and other beam control, so cut off Most of the uses use CO 2 laser processing machines. At present, YAG lasers using optical fibers are more than CO 2 lasers for welding applications, and in the use of cutting, CO 2 lasers are often used for the above mechanism.

The future development trend is that with the expansion of the scope of laser processing machines, it will become more and more difficult to ensure that the specialists who can operate the laser processing machine will be able to operate a plurality of types of processing machines, or no one should always look at them. A processing machine that can run alone.

In order to respond to the above trends, we should focus on the following laser cutting technologies:

(1) Improve the performance of continuous processing Reduce the number of maintenance, reduce the stop time of the processing machine; predict the failure before the occurrence of the prevention, prevent the need to adjust the part; minimize the linkage with the shelf.

(2) Improve operability Simplify the operation function of the control device; enrich the function of automatic processing; complex operation is indicated by the control device; easy to network.

According to the problems encountered by users during use, the following suggestions are made:

(1) For application companies, if they only want to meet the needs of mass production, they should choose a special working machine suitable for repeated processing; if research and development of multi-species small-scale production is also carried out at the same time, flexible processing methods are needed. Laser cutting has potentially huge market demand in China, and there will be more and more such research or development necessity in the future.

(2) Laser cutting has no need for a mold, the machining program can be completed in a short time, and the material of the processing object can be flexibly matched when the material of the object is changed. The non-contact processing has higher precision and the like, and is suitable for trial processing or Research and development methods such as small-scale production of multiple varieties.

(3) The application of laser cutting is not limited to the cutting of sheet metal, but it can also be used for the production of simple molds for forming such as bending and drawing. Such simple molds are not used for mass production, but to meet the requirements for shortening the test inspection time. From trial production to formal production, it is a requirement of modern society to shorten the preparation time as much as possible, and laser processing is one of the few processing methods that can meet such requirements.
