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 strength and hardness due to cold work hardening; the utilization rate of CNC turning machine thread turning machining is high; The yield is doubled compared to the cutting process 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 die are also high, and the manufacturing of the mold is difficult; it is not suitable for rolling the wrongly-defined thread.
Secondly, the CNC CNC lathe thread turning processing method has the following methods. According to the different molds, the thread rolling can be divided into two types: the twisting wire and the rolling thread: 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.
Rolling technology for CNC turning machine thread turning is generally carried out in thread rolling machines, thread rolling machines or automatic lathes with automatic opening and closing thread rolling heads. It is used in high-volume production scale 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.
