Study of Using Internal Thread Whirling in Machining Titanium Dental Implant

摘要

Swiss-type lathe is the machine tool of choice in machining titanium dental implants. It is able to do turning, drilling, and milling in a single setup. One of the more challenging processes is the internal threading at one end of the dental implants. Threading in titanium at as little as M1.4 and as deep as 6mm possesses certain difficulties in terms of chips disposal, BUE, tool wear, and tool breakage. The study focuses on internal threading whirling. A new method of applying cutting fluid jet has been tested. The experiments have been done by using the Swiss-type lathe, Star SR-20R.
