Abstract: Because of particularity and plexity of process thread structure, thread processing has low accuracy, low efficiency. Aiming at these problems, points out that in the thread processing, by selecting the appropriate programming instruction, correct processing tool, workpiece clamping and reasonable use of accurate cutting parameters, can accurately control thread in CNC lathe processing, high precision, high efficiency, stable and reliable manufacture thread products qualified. Don39。t screw the traditional processing methods to meet the production requirements of high efficiency, high quality. Through the process of an instance of rational planning of production, based on process analysis of a threaded shaft, piled NC program, to verify the correctness of NC programming and process, to provide a meaningful reference for NC machining of the parts. And in the machining center processing of the products and meet the technical requirements of products. Because a clamping molding, greatly improved work efficiency.
