Analysis of CNC Transformation of Machine Tools and Production Lines

The rise of foreign transformation industry in developed countries such as the United States, Japan and Germany, their machine tool transformation as a new economic growth industry, business is full, is in the golden age. Due to the continuous advancement of machine tools and technology, machine tool transformation is an "eternal" subject. China's machine tool transformation industry has also entered the new industry dominated by numerical control technology from the old industry.

In the United States, Japan, and Germany, the use of numerical control technology to transform machine tools and production lines has a broad market, and has formed a new industry for machine tool and production line CNC transformation. In the United States, the machine tool transformation industry is called the machine tool regeneration (Remanufacturing) industry. Well-known companies engaged in the recycling industry are: Bertsche Engineering, Ayton Machine Tool, Devlieg-Bullavd (Dabao) Service Group, US Equipment Company, etc. American Depot has opened a company in China. In Japan, the machine tool transformation industry is called the Retrofitting industry. Well-known companies engaged in the conversion industry include: Otsuka Engineering Group, Gangsan Machinery Co., Chiyoda Machinery Co., Ltd., Nozaki Engineering Co., Hamada Engineering Co., Ltd., Yamamoto Engineering Co., Ltd., etc.

The content of CNC transformation:

The main contents of the numerical control transformation of machine tools and production lines are as follows:

(1) to restore the original function, diagnose and recover the faulty parts of the machine tool and the production line;

(2) It is NC, and the digital display device is added to the ordinary machine tool, or the numerical control system is added, and the NC machine tool and the CNC machine tool are transformed;

(3) It is a refurbishment. In order to improve the accuracy, efficiency and automation, the mechanical and electrical parts are refurbished, the mechanical parts are reassembled and processed, and the original precision is restored; the CNC system that does not meet the production requirements is updated with the latest CNC;

(4) It is a technological update or technological innovation. In order to improve performance or grade, or to use new technologies and technologies, large-scale technical updates or technological innovations are carried out on the original basis, and the level and grade update are greatly improved. Transformation.

(5) Advantages and disadvantages of numerical control transformation:

1. Reduce investment and short delivery time.

2. Compared with the purchase of a new machine tool, it can generally save 60% to 80% of the cost, and the transformation cost is low. Especially for large and special machines, it is especially obvious.

3, the general large machine tool transformation, only spend 1/3 of the new machine tool purchase costs, the delivery time is short. However, in some special cases, such as the production and installation of high-speed spindles and pallet automatic exchange devices, it is too laborious and costly. The cost of retrofitting is often increased by 2 to 3 times. Compared with the purchase of new machine tools, it can only save about 50% of investment.

4. The mechanical properties are stable and reliable. The basic parts such as the bed and column used for the limited structure are heavy and solid casting components, not the welded components. The modified machine tool has high performance and good quality and can be used as new equipment. Continue to use for many years.

5, but subject to the limitations of the original mechanical structure, it is not appropriate to make a breakthrough transformation. Familiar with the equipment, easy to operate and repair, buy new equipment, do not understand the new equipment.
