Title:
ULTRASONIC VIBRATION ASSISTED SPIRAL THREAD MILLING AND GRINDING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/052267
Kind Code:
A1
Abstract:
Disclosed is an ultrasonic vibration assisted spiral thread milling and grinding method. A profiling grinding wheel cutter (3) is used, and the profiling grinding wheel cutter (3) is mounted on a spindle (1) of an ultrasonic machining tool by means of an ultrasonic vibration cutter holder (2); and the axis of the cutter is arranged parallel to the central axis of a threaded hole, and a spiral milling mode formed by combining four movements comprising spinning of the profiling grinding wheel cutter (3), revolution of the profiling grinding wheel cutter (3) around the axis of the threaded hole, axial feeding of the profiling grinding wheel cutter (3) and axial vibration of the profiling grinding wheel cutter (3) along with the ultrasonic vibration cutter holder (2) is adopted. By means of the ultrasonic vibration assisted spiral thread milling and grinding method, a cutting force for hard and crisp materials difficult to machine during thread machining can be reduced effectively, and abrasion of the cutter is improved.
