CNC lathe thread turning technology

        Rolling technology for CNC turning machine thread turning is generally carried out in thread rolling machines, thread rolling machines or on automatic lathes with automatic opening and closing thread rolling heads. It is suitable for mass production of standard fasteners and other threaded couplings. External thread. Rolling CNC CNC lathe thread turning parts generally have an outer diameter of not more than 25 mm, a length of not more than 100 mm, and a thread precision of 2 (GB197-63). The diameter of all blanks is approximately equal to the diameter of the thread to be machined. . Rolling generally cannot be machined, but for workpieces with softer material, the grooveless extrusion tap can be used to cold-squee the internal thread (up to a diameter of up to 30 mm). The working principle is similar to tapping. The torque required for cold extrusion of the internal thread is about 1 times larger than the tapping, and the machining accuracy and surface quality are slightly higher than the tapping.

       "CNC Lathe Thread Turning Machining Technology" is very particular in CNC machining of CNC lathe thread turning. Here, from Suzhou Meidis Precision Machinery Co., Ltd., you can bring professional CNC lathe machining, CNC lathe thread Turning, thread turning technology for CNC lathe machining technology:

First of all: the advantages of thread turning of CNC lathes are: surface roughness is less than turning, milling and grinding; the surface of the thread after rolling can improve the strength and hardness due to cold work hardening; the material utilization rate of CNC turning machine thread turning machining is high; productivity It is multiplied more than cutting and is easy to automate; the rolling die has a long life. However, the rolling thread requires that the hardness of the workpiece material does not exceed HRC40; the dimensional accuracy of the blank is required to be high; the precision and hardness of the rolling mold are also high, and it is difficult to manufacture the mold; it is not suitable for the rolling of the tooth profile.

         Secondly: CNC CNC lathe thread turning processing method has the following, according to the different molds, the thread rolling can be divided into two types: twisting wire and rolling wire: Two silk threaded dies are arranged in a staggered 1/2 pitch. The static plate is fixed, and the moving plate is made to reciprocate linear motion parallel to the static plate. When the workpiece is fed between the two plates, the moving plate advances to press the workpiece, and the surface thereof is plastically deformed into a thread. There are three types of thread rolling: radial rolling, tangential rolling and rolling head rolling. Radial rolling: Two (or three) threaded rolling wheels are mounted on mutually parallel shafts, the workpiece is placed on the support between the two wheels, and the two wheels rotate in the same direction at the same speed.
