Introducing chipless taps into production it is necessary to take into account factors arising from the specifics of the method and factors affecting economic efficiency.
Significant effect from the introduction of the machine method of manufacturing threaded holes in stainless steels with brushless taps can be obtained only if the complex of measures is observed, related to the choice of the optimum hole diameter and the quality of preparation of the hole for the thread, the choice of mounting the tap on the machine, the speed of thread extrusion, coolant equipment and others.
A new contour design has been proposed in the paper to prevent damage to the instrument for the manufacture of internal threaded holes. In addition, the design allows to replace quickly the instrument to another size.
The designed construction of the cartridge ensures the centering of the tool over the hole being machined and ensures the transmission of torque of the required size. Analytical dependencies and computational schemes that ensure the operability of the device are derived.
