Five-axis linkage machine leads Chinese dream

For a country's aviation, aerospace, military, scientific research, precision equipment, high-precision medical equipment and other industries, five-axis CNC machine tools have a decisive influence. Now, it is generally believed that the five-axis linkage CNC machine tool is the only means to solve the processing of impellers, blades, marine propellers, heavy-duty generator rotors, turbine rotors, large-scale diesel crankshafts, and so on. Therefore, whenever people face difficulties in designing and developing complex surfaces, they often turn to the five-axis CNC system. As the five-axis CNC machine tools are very expensive, and the NC program is difficult to produce, the five-axis system is difficult to "civilian" application. However, in recent years, with the development of computer-aided design (CAD) and computer-aided manufacturing (CAM) systems, breakthroughs have been made. Many CNC companies in China, such as Shanxing, have launched five-axis CNC machine tools, breaking the foreign technology blockade. Occupy the highest point of this strategic industry, greatly reducing its application costs, so that China's equipment manufacturing industry ushered in a new era.

The domestic manufacturers that produce five-axis linkage machine tools currently include: Shenyang Machine Tool, Dalian Machine Tool, Qi 2 Machine Tool, Sichuan Changzheng Machine Tool, North Second Machine Tool, Jiangsu Xinrui Heavy Industry, etc. Shandong Yonghua Machinery Co., Ltd. is also one of them. Chen Zhou, general manager of the company introduced the company's five-axis linkage machine tool can be processed out of the precision of three thousandths of a millimeter, which is one-twentieth of a hair. Applicable to the current aviation, aerospace, medical, precision instruments and other industries.

Shandong Yonghua Machinery Co., Ltd. was established in 2007. Its main products include large-scale gantry machining centers, high-precision horizontal machining centers, and high-speed vertical machining centers. The company has set up sales service offices in more than a dozen key provinces and cities nationwide. The products are widely used in many fields such as automobile, shipbuilding, electronics, and mold manufacturing. Some high-end machine tools have been exported to the European market. In 2008, the company passed the ISO9001 international quality system certification. In 2010, it has become the largest R&D and production enterprise in the southwest of Shandong Province. Its product quality and service level are all in the leading position in the industry.

In 2010, it invested RMB 100 million to start the second-phase processing center light engine project. It was completed and officially put into production in 2012. This project has the largest 15,000 square meters constant temperature dust-free assembly plant in the industry, and uses the latest energy-saving and environmentally friendly ground source heat pump technology. The constant temperature purification control for the entire workshop has added more than 20 sets of imported high-precision processing equipment and testing instruments, which has laid a solid foundation for Yonghua's production of various kinds of high-precision machining center hosts.

If the ordinary machine tool is likened to "embroidery" on the plane, then the "five-axis linkage" technology is a three-dimensional "sculpture" on steel, which can sculpt a piece of hard steel into a smooth and graceful "lotus". This high-precision processing technology, which has been mastered by developed countries in Europe and America, was recently conquered by Shandong Yonghua Machinery for many years.

Concerns about the five-axis linkage have only increased. Not long ago, the VGW400-U high-speed, high-precision, five-axis vertical machining center of Dalian Kede CNC Co., Ltd. was exported to Germany and was proud to be exported for the first time in China. The product reflects the superior performance of domestic high-end CNC machine tools and high-end CNC systems and functional components.

The use of five-axis linkage machines makes it easy to set up the workpiece. No special fixtures are needed during processing, which reduces the cost of fixtures, avoids multiple fixtures, and improves mold machining accuracy. The use of five-axis machining tools can reduce the number of fixtures used. In addition, because the five-axis linkage machine can eliminate many special tools during machining, tooling costs are reduced. The five-axis linkage machine tool can increase the effective cutting edge length of the tool during machining, reduce the cutting force, increase the service life of the tool, and reduce the cost. Many advantages are combined into one. It is believed that in the near future, with the popularization and promotion of 5-axis CNC machine tools, it will surely lay a solid foundation for China to become a world power.
