High-speed lathe linear motor

Linear motors can be seen from the process of continuous innovation of high-speed machining centers. Taking full advantage of the latest achievements in today's technology field, especially the latest achievements of drive technology and control technology, is to continuously improve the high-speed performance, dynamic characteristics and machining accuracy of machining centers. key.

Most high-speed machining centers or CNC lathes still use servo motors and ball screws to drive linear coordinate axes, but some CNC lathes have already used linear motors, such as the RXP500DS / RXP800DS high-speed milling machines from Germany R & ouml; ders and Dejima's DMC75V linear high-speed machining center (its axis acceleration reaches 2g and its fast stroke speed reaches 90m / min). Because this linear drive eliminates the need for a transmission element that converts slewing motion into linear motion, the dynamic performance, moving speed, and machining accuracy of the shaft can be significantly improved.

Machines powered by linear motors can significantly increase productivity. For example, when machining electrodes for electrical discharge machining, the machining time is reduced by 50% compared with the use of traditional high-speed milling machines.

Linear motors can significantly improve the dynamic performance of high-speed machine tools. Since the molds are mostly three-dimensional curved surfaces, the tool axis must be continuously braked and accelerated when the tool is processing curved surfaces. Only with high axis accelerations can it be possible to track a given contour with a constant per-tooth feed on short path paths at high path speeds. The smaller the radius of curvature of the surface contour, the higher the feed rate, the higher the required axis acceleration. Therefore, the axis acceleration of the machine tool greatly affects the machining accuracy of the mold and the durability of the tool.

High-speed lathe torque motor

On high-speed lathes, the swinging of the rotary table and the swinging and turning of the fork-shaped spindle head have been widely implemented by torque motors. A torque motor is a synchronous motor. Its rotor is directly fixed on the part to be driven, so there is no mechanical transmission element. It is a direct drive device like a linear motor. The angular acceleration that the torque motor can achieve is 6 times higher than that of the traditional worm gear and worm gear, and the acceleration can reach 3g when the fork head is swung. Because the torque motor can achieve extremely high static and dynamic load rigidity, the positioning accuracy and repeatability of the rotary and swing axes are improved.

It should be mentioned that the combination of the directly driven linear axis and the directly driven rotary axis makes all the movement axes of the machine tool have high dynamic performance and adjustment characteristics, so that the mold can be processed freely for high speed, high precision and high surface quality Surfaces provide the best conditions.
