Machining Platinum Rings - Do's and Dont's

Abstract:
The processes involved in machining platinum have long been based on whatever experiences were available to the machinist or manufacturing professional. This condition is due in part to limited published information available to manufacturing professionals regarding specifically platinum and platinum group alloys.
In my 12 years of machining platinum and the precious metal group alloys, I have been through many manufacturing experiences both good and bad. It is my aim to share these experiences in the following topics with regards to platinum manufacturing.

•Advances in machine tool technology.
•Advances in PCD and consumable tooling technology.
•Common misconceptions about required tooling geometry.
•Strategies for effective recovery of precious metal.
•Process automation for ring blank production.

Hopefully this will aid the first time or even the long time jewelery manufacturer to avoid the common pitfalls related to the production of fine platinum jewelery.

•Advances in Machine Tool Technology-
There have been a huge number of advances in the technology of chip cutting machine tools over the last five years. The advantages for metal products manu facturers of any size are many.
