    Structural characteristics of thread cutters
    The threading tools of threading tools manufacturer are tools for processing threads by cutting methods, and tools for processing threads by plastic deformation methods.
    Thread cutter introduction:
    The collective term for thread cutters and thread rolling cutters. The former is a tool that uses cutting methods to process threads, such as taps, dies, thread turning tools, thread milling cutters, automatic thread cutting heads, etc.; the latter is a tool that uses plastic deformation methods to process threads, such as thread rolling plates and rolling wheels, automatic Opening and closing thread rolling heads and grooveless extrusion taps, etc.
    Structural characteristics of thread cutters:
    Taps and molds are standard tools for processing or trimming internal and external threads, with simple structure and convenient use. The thread turning tool can be used for turning internal and external threads. It is a profile turning tool with the same profile as the thread. There are three types: flat, prismatic and circular. The thread comb is a multi-tooth thread turning tool with rough cutting teeth and fine cutting teeth, so threads can be machined in one or multiple cutting strokes. There are three types of thread milling cutters: disc milling cutter, comb milling cutter and whirlwind milling cutter (see whirlwind cutting). Disc thread milling cutters are mainly used to process trapezoidal threads and worms with large pitches. Comb-tooth thread milling cutter is a ring-shaped tooth milling cutter. All threads can be cut out when the workpiece rotates 1.25 to 1.5 revolutions.
    There are oblique tooth patterns on the thread rolling plate, the tooth profile is the same as the thread profile of the workpiece, and the bevel angle is the same as the thread rising angle of the workpiece. When working, the static plate and the movable plate are paired. There are three parts on the static plate: pressing in, correcting and withdrawing. The thread rolling productivity is high, but the machining accuracy is low, and it is suitable for machining screws with a diameter of less than 20mm. The surface of the roller is made of multiple threads, the threads on the two rollers are opposite to the threads of the workpiece, and the thread lift angle on the pitch diameter of the roller is equal to the diameter of the thread lift angle workpiece on the pitch. In order to enhance the rigidity of the mandrel and increase the life of the thread rolling wheel, the diameter of the thread rolling wheel must be enlarged, so the thread rolling wheel is made of multiple threads. The number of lines n=D2/d2=s/t, where D2 is the pitch diameter of the rolling wheel; d2 is the pitch diameter of the thread of the workpiece; s is the thread lead of the rolling wheel; t is the pitch of the workpiece. The structure of the automatic opening and closing thread rolling head is similar to that of the automatic opening and closing thread cutting head. When the thread rolling reaches a predetermined length, the three rollers will automatically open, and the thread rolling head can be quickly retracted. Slotless extrusion taps are formed by plastic deformation of metal when extruding the hole wall.
