THREAD MACHINING APPARATUS, METHOD AND SYSTEM

WIPO Patent Application WO/2024/007170

A1

Embodiments of present disclosure relate to thread machining apparatus (300), method and system. The thread machining apparatus (300) comprises: a spindle motor (310) adapted to drive a thread tool (200) coupled to an output shaft of the spindle motor (310) to rotate at a rotational speed; and a feeding device (320) movably coupled to the spindle motor (310), and configured to drive the spindle motor (310) to move along an axial direction (X) of the spindle motor (310) at a moving speed; wherein during thread machining, the moving speed is proportional to the rotational speed. The solutions of the embodiments of present disclosure have significantly improved the efficiency, stability and accuracy of thread machining.
