In the past ten years, the progress of driving technology and control system has promoted the continuous innovation and performance improvement of the processing center structure. The application of electric spindle, linear motor, torque motor and fast numerical control system plays a decisive role in improving the high-speed, high dynamic and high machining precision of machining center.
Machine tools driven by linear motors can significantly increase productivity. For example, in the processing of electrodes for EDM, the processing time is reduced by 50 % compared to the use of traditional high-speed milling machines.
Linear motor can significantly improve the dynamic performance of high-speed machine tools. Since most of the molds are three-dimensional surfaces, the tool shaft must be constantly braking and accelerating when machining the surface. Only with a higher axial acceleration can a given profile be tracked with a constant feed per tooth on a shorter trajectory path at a high trajectory speed. If the curvature radius of the surface contour is smaller, the higher the feed speed, the higher the required axial acceleration. Therefore, the axial acceleration of the machine tool greatly affects the machining accuracy of the die and the durability of the tool.
Nowadays, machine tools are developing in the direction of high precision, high speed, high compound, high intelligence and environmental protection. High precision and high speed machining put forward higher requirements for transmission and its speed regulation: higher dynamic characteristics and speed regulation accuracy, higher feed speed and acceleration, lower vibration noise and less wear. The application of linear motor and its driving speed regulation technology in the machine tool feed drive has made the transmission structure of the machine tool change greatly, and has made a new leap in the performance of the machine tool.
With the rapid development of high-speed machining technology, the requirements for transmission and control system are getting higher and higher, so that the research of linear motor driving technology is gradually increasing. Increasing research on straight-line driving technology not only leads to a higher and faster development of the technology, but also better meets the needs of the market and brings more economic benefits.
