CNC precision parts machining usually refers to computer digitally controlled precision machining, CNC machining lathes, CNC machining mills, CNC machining boring mills, etc. High productivity in multi-species and small batch production, which reduces the time required for production preparation, machine adjustment, and process inspection, and reduces cutting time due to the use of better cutting volume. The CNC machining quality is stable, with high machining accuracy and repeatability, and is adapted to the machining requirements of aircraft.
CNC machining center control system can generally be by the digital program instructions to control the machine tool to end the spindle automatically start and stop, reversing and variable speed, can automatically control the feed speed, direction and processing path, processing, can select the tool and according to the tool scale to adjust the amount of tool eating and walking trajectory, can end the processing of the various auxiliary actions required.
The structure of CNC machining CNC lathe is also composed of a spindle box, tool holder, feed transmission system, bed, hydraulic system, cooling system, lubrication system, and other parts, only the feed system of the CNC lathe and the feed system of the horizontal lathe are essentially different in structure, the mechanical structure of typical CNC lathe is composed of the diagram.
The movement of the spindle of the horizontal lathe is transmitted to the tool holder through the hanging wheel holder, feed box, and skid box to end the longitudinal and transverse feeding movement. And the CNC lathe is selected servo motor, which is transmitted to the slide plate and tool holder through ball screw to end the z-direction (longitudinal) and displacement (transverse) feeding motion.
The fine CNC lathe also has various thread functions, and the motion contact between spindle rotation and tool holder movement is controlled by the CNC system.
