Titanium Machining

In recent years, titanium has become dramatically more significant as a workpiece material in machine shops. Two industries are driving this. One is aerospace. The latest aircraft designs use dramatically more titanium than planes of the past. The other is the medical industry. Titanium is a common material used for implants and devices used within the body. Titanium’s high hardness and low thermal conductivity make it more challenging to machine than other metals that most machine shops are more accustomed to facing.

The Benefits of Horizontal Turning on a Mill-Turn Machine

By: Mark Albert
A mill-turn machine that can rotate a large, bell-shaped workpiece in a horizontal orientation enabled this manufacturer to hit tight tolerance and cost targets. Minimizing non-value-added time and running lights out were also essential for success.
