Intermetallic Nickel-Titanium Alloys for Oil-Lubricated Bearing Applications

August 1, 2009

Nitinol 60 (60NiTi), an intermetallic nickel-titanium alloy containing 60 wt % nickel and 40 wt % titanium, is shown to be a promising material for oil-lubricated, rolling and sliding contact applications such as bearings and gears.

Axis of Rotation Metrology

August 1, 2009

In the history of machine tools, spindles have been very good relative to other bearings and structures on the machine. So quality professionals have developed a cache of tools—-ball bars, grid encoders displacement lasers, etc.—-to help them characterize and understand the geometry of the structural loop. But as machine tools have improved in their capability and precision, and the demands of part-geometry and surface finish have become more critical, errors in spindles have become a larger percentage of the total error.
