Direct drive technology represented by linear motor in the direction of CNC machine tool development. The domestic CNC machine tools have so far gone through a long process of development in the "40 +10" year. The first 40 years were slow exploration stages. In the past 10 years, under the impetus of relevant government policies such as "Made in China 2025", they ushered in rapid development.
According to the knowledge of the small series of linear Motors, at present, more than 1,500 kinds of domestic CNC machine tools are available, covering CNC metal cutting machine tools, CNC plate processing machine tools, CNC electrical processing machine tools, industrial robots, and three-coordinate measuring machines.
Quality and efficiency is an important topic and goal of mechanical manufacturing research, and it is the source of driving force to promote the development of its process equipment. Therefore, how to improve quality and efficiency has always been the key point for NC machine tool manufacturers to consider. Therefore, direct-drive technology has become one of the directions. The main shaft adopts the electric spindle direct drive, the feed adopts the linear motor drive, the rotary table adopts the torque motor direct drive, and the five-axis linkage adopts the torque motor direct drive.
As early as 2000, our country started the research and development of direct drive technology. At present, Shandong Bote Seiko Co., Ltd. and Luoxian Research Technology Co., Ltd. can produce and supply electric spindle series products. Shoukekaiqi Electric Technology Co., Ltd. and Kunshan Tongmao Electronics Co., Ltd. have also developed linear Motors. Users responded well to the above product performance and technical indicators. Among them, it is worth emphasizing that the linear motor products of Kunshan Tongmao Electronics Co., Ltd. are 70 % exported to developed regions such as Europe and the United States.
What are the outstanding advantages of linear motor driven CNC machine tools? It is reported that in the machine tool feed system, the difference between the use of linear motor direct drive and the original rotary motor drive is to eliminate the mechanical transmission link between the motor and the workbench(drag board), and shorten the length of the machine tool into the transmission chain to zero. Therefore, this transmission method is also called "zero transmission." It is precisely because of this "zero transmission" method that it brings about the performance indexes and advantages that the original rotary motor drive method can not achieve.
Kunshan Tongmao Electronics Co. Ltd. has been focusing on the research and development and production of linear motors for ten years. Professional technical personnel for you to select, assist in providing customization and solutions, the whole process for you to solve all the problems in the linear motor installation, so that you can easily purchase and use.
