Nowadays, the most popular automotive bearing suppliers is to apply them to high-speed parallel mechanisms, namely six Axis and three-axis parallel structure machine tools control the tool through the expansion and contraction of multiple sliding plungers to realize high-speed machining of complex profiles.
The high-precision micro-feed device is now available Become an important key device for super precision machine tools. Inchworm type piezoelectric ceramic motors are composed of three individually controlled tubular ceramic piezoelectric devices, of which A and B are radially stretched and contracted. In ultra-precision machine tools, in order to perform online compensation of machine tool machining errors to improve the shape accuracy of the machining; to process some special non-axisymmetric surfaces, a micro-feed device is required. In the field of high-speed and ultra-high-speed machining,
linear motors are widely used in high-speed milling machines, crankshaft lathes, ultra-precision lathes, grinders, laser lathes, etc.2m/min, and the acceleration is α=1~1. A typical example in application is the XHC240 high-speed horizontal machining center developed by Ex-cell-o in Germany. Ultrasonic motor (USM) is a new type of direct drive motor that has received increasing attention at home and abroad. .2 Application in ultra-precision processing Ultra-precision processing is a cutting-edge science in the manufacturing industry
