Title:
METHOD AND DEVICE FOR PRODUCING AN INTERNAL THREAD BY AUTOMATICALLY MACHINING IN A BORE
Document Type and Number:
WIPO Patent Application WO2005097388
Kind Code:
A8
Abstract:
The invention relates to a method for producing a thread in a bore (2) by remote automatic machining characterised in that said method consists in introducing into the bore (2) an electrode (11) provided with a thread (20) whose shape and dimensions are pre-determined according to the shape and dimensions of an inside thread to be produced, in machining the internal threads by electroerosion displacing the electrode (11) in an orbital manner in the bore (2) according to a predetermined number of operations and in adjusting the machining parameters according to each operation. A device for carrying out said method is also disclosed.
