Innovation of linear motor driving technology for CNC machine tools. In recent years, domestic and foreign CNC machine tool companies have devoted themselves to developing various types of CNC machine tools with automatic and intelligent functions to meet the requirements of machine tool users for "high speed, high precision, high responsiveness, high efficiency, and environmental protection" of CNC machine tools. Especially these two years, Under the impetus of Internet and information technology and artificial intelligence technology, CNC machining has gradually shown the trend of network and intelligence.
And in the CNC machine tool more and more advanced, intelligent road, the linear motor has played a pivotal role! The feed transmission method of "rotating motor + ball screw" used in traditional machine tools is difficult to improve in terms of feed speed, acceleration, and rapid positioning accuracy due to the limitations of its own structure. It is impossible to meet the demands of high-speed cutting precision machining on the servo performance of machine feed system. In this case, the machine tool manufacturer sees the advantage of a linear motor, which converts electrical energy directly into linear motion mechanical energy without the need for any intermediate conversion mechanism. It has the advantages of large starting thrust, high drive stiffness, fast dynamic response, high positioning accuracy, and unrestricted stroke length. It has begun to innovate the CNC machine tool technology and uses a linear motor to replace the "rotary motor + ball screw".
In the machine tool feed system, the difference between the direct drive of the linear motor 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.
