The AES Spiral Tap is a tool used in machining, primarily in threading. It is used to machine threads on the surface of cylindrical workpieces to meet thread specifications. The main feature of the spiral tap is the helical arrangement of the cutting edges, which are used to cut the thread into the surface of the workpiece to form the thread.

AES screw taps are used by drilling a hole in the surface of the workpiece to be machined, inserting the screw tap into the hole, and rotating the screw tap so that it cuts the surface of the workpiece to form a thread. Spiral taps play an important role in thread machining, which can improve the precision and quality of the workpiece.

In addition to its role in threading, the AES Spiral Tap can be used to remove burrs and residual material from the surface of a workpiece, thereby improving the surface finish and accuracy of the workpiece. In addition, it can be used to repair damaged threads and restore the original function of the workpiece.

Overall, the role of AES Spiral Tap in machining is mainly used for thread machining to improve the precision and quality of the workpiece, and it also has the functions of deburring and repairing threads. It is an indispensable machining tool, widely used in various machining fields.
