China Machine Tool Remanufacturing Innovation Model

China Machine Tool Remanufacturing Innovation Model

Recently, the China Development and Reform Commission jointly with the Ministry of Finance, the Ministry of Industry and Information Technology, the Ministry of Commerce, and the General Administration of Quality Supervision, Inspection and Quarantine have released the "Re-manufactured Products" trial and implementation plan for re-launching of remanufactured products, and vigorously supported the promotion and use of remanufactured products to expand market share. The entire work was formally implemented in 2013. Recently, Wuhan Huazhong Automatic Control Technology Development Co., Ltd., one of the first batch of machine tool remanufacturing companies, has received good news. While successfully listed in the third batch of remanufacturing product catalog newly released by the Ministry of Industry and Information Technology, the company is remanufactured by Harbin Electric Machinery Factory. A heavy-duty general-purpose milling and boring machine has been successfully completed and delivered soon, becoming another successful example of machine tool remanufacturing.

It is reported that this is a British product (ASQUITH 254) manufactured in 1960. After long-term use, it has serious wear, loss of accuracy, low efficiency, and high failure rate, which seriously affects user production. Large equipment such as: bed, slider, column, balance hammer and other re-use value (the four major pieces of good rigidity, a total of more than 87% of the total weight of the machine tool). In order to reduce losses and waste, Harbin Electric Factory commissioned Huazhong Automation to remanufacture it and upgrade it into a brand new modern HF6926 CNC floor-standing milling and boring machine. After re-optimizing the design of the machine, in addition to borrowing ASQUITH 254's original bed, slides, columns, and large counterweights, the rest of the components, CNC systems, hydraulic systems, pneumatic systems, and functional accessories are all based on user requirements. Upgrade, especially as the main drive mast of the headstock of the boring and milling machine, performs the remanufacturing optimization design and remanufacturing, and the idea of ​​humanity, advancement, safety, and reliability runs through every design step.

This machine is a CNC floor-type milling and boring machine with the largest specification and self-weight in the same type of machine tool. It has the advantages of good rigidity under heavy cutting and stable equipment. After the remanufacturing, the technology is advanced, the structure is mature and reliable, the performance is improved, the function is expanded, the configuration of main parts and key parts is high, the work operation is stable, and the production efficiency is high. From the overall performance and technical indicators have reached or even exceeded the level of the same type of machine tools. Compared with the purchase of the same domestically produced new equipment, users have saved more than half of the cost, which fully demonstrates that remanufacturing has good economic and social benefits.

It is understood that although the Chinese remanufacturing industry started relatively late, some remanufacturing technologies have reached or even exceeded the international advanced level.

CO2 LASER CUTTERS

CO2 laser cutters are the perfect tools for engraving your favorite designs in acrylic, thin woods and numerous more materials. These machines, which provide excellent value for the price, can engrave complex designs quickly and accurately while leaving behind minimal wood dust or metal shavings. Within our selection, you`ll find CO2 laser engravers with power options of 40W up to 260W.


CO2 laser machines function by essentially bouncing light emissions between mirrors until the beam is strong enough to penetrate a partially transparent mirror at the tip of the laser head. These lasers are capable of cutting wood, metal and other materials.
