1) Optimization of thread profile

The basic thread profile of ordinary threads is a flat top and flat bottom shape, which is currently widely used thread profile. Its main advantages are simple thread profile structure and good thread processability for Precision machine taps; The disadvantage is that there are sharp corners on the top and bottom of the threaded teeth of Precision machine taps, which can easily cause stress concentration during use, reduce the strength and fatigue strength of Precision machine taps, and generate grinding burrs at the sharp corners of the threads, exacerbating coating peeling and Mechanical tap wear.

In this case, it can be said that the thread profile of the extruded Mechanical tap is designed in a dome shaped circular bottom shape, which meets the thread tolerance and testing requirements of the national standard for ordinary threads.

2) Remove incomplete teeth

In addition to optimizing tooth design, corresponding optimizations can also be made to the manufacturing process of extruded Precision machine taps. Choosing appropriate processing techniques to effectively remove incomplete teeth at the front end of the extrusion cone is crucial for improving the smoothness of the machined hole threads, reducing tapping torque, and increasing the service life of Precision machine taps.

3) Passivation and polishing treatment

Using mechanical contact grinding passivation method to passivate and polish the surface of extruded Precision machine taps. The main process method is to fully insert the threaded part of the Mechanical tap into the grinding powder, and let the Mechanical tap rotate and revolve in the grinding powder. By setting the steering, speed, and time, the Tap manufacturer achieves the purpose of polishing and passivation. The threaded parts of Precision machine taps that have been passivated and polished are smoother, brighter, and free of burrs.
