Actually everyone should know the CNC machine tool, in fact, the mechanical structure compared with the general use of machine tools is a big change, only in the automatic transmission, and rest and workbench automatically and handle operation made a few changes, with the continuous development of numerical control technology, considering the control mode and use characteristics.In order to improve the working conditions, reduce the auxiliary time, improve the operability, improve the labor productivity, the use of the tool automatic clamping device, so it has a relatively high static machine tool, and operating stiffness.
Bearing nc machine tools is according to the numerical control programming, or manual input data, provide the instructions of the workpiece processing, due to the mechanical structure of positioning errors caused by geometric accuracy and deformation in the process of processing can 0010010 #39;t think of adjustment and compensation, so we must produce the elastic deformation of mechanical structure parts throughout the control within small limits, to ensure that the required machining accuracy and surface quality, in CNC bearings, actually played a relatively good performance, in general are better than ordinary lathe performance at all.
