The author conducts a simple experiment to verify his anecdotal knowledge about chamfering hard vs soft parts.

The latest technological solutions help keep chamfering and deburring operations in-line -- often without increasing cycle times.

Chamfering and deburring have been described as "unloved," a "necessary evil" and, in fact - "dead." After all, manual deburring is still common in many shops.

Chamfering and deburring of cylindrical gears does not get much love from manufacturers. The process is seen as a necessary evil since it is adding cost without adding value. However, there are good reasons for not underrating this important auxiliary process. Chamfering and deburring takes care of several issues which may come up during the manufacture of quality gears.

The objective, according to Dr.- Ing. Hansjörg Geiser, head of development and design for gear machines at Liebherr, was to develop and design a combined turning and hobbing machine in which turning, drilling and hobbing work could be carried out in the same clamping arrangement as the hobbing of the gearings and the subsequent chamfering and deburring processes.

Banyan Technologies introduces a robotic chamfering device suitable for deburring, chamfering and radiusing the edges of slew bearing ring gears.

Several innovations have been introduced to the gear manufacturing industry in recent years. In the case of gear hobbing—the dry cutting technology and the ability to do it with powder-metallurgical HSS—might be two of the most impressive ones. And the technology is still moving forward. The aim of this article is to present recent developments in the field of gear hobbing in conjunction with the latest improvements regarding tool materials, process technology and process integration.

New tool from LMT-Fette provides combination of operations.

The seemingly simple process of placing a uniform chamfer on the face ends of spur and helical gears, at least for the aerospace industry, has never been a satisfactory or cost effective process.
