We see from your search that you're looking for information on the term "Surface Roughness",
and we have a large number of manufacturers' news releases and technical articles here on Manufacturingtalk which will be of interest.
Let me be your guide.
Start with
the news release High precision reference flats introduced from
Optical Surfaces, which we summarised at the time by saying "High precision reference flats are versatile devices for measuring surface flatness of polished areas by determining the variations between work surfaces and the surface of the optical
flat".
A few weeks before,
we featured the news release Play a major role in preseving natural resources from
NSK UK: "Rolling bearings are indispensable to machinery and equipment; their function is crucial in the role of transferring rotational energy with minimal energy loss: i e, energy conservation".
In September 2007, we covered the news from Keronite
concerning its Keronite technology
- take a look at Mould surfaces made more durable
which says: "Aluminium is used as a replacement for expensive steel tools using patented chrome-free Keronite technology, improving durability and surface release properties".
Take a look also at the news release from Keronite, Aluminium tools reduce volume moulding costs,
as well as Bench device tests surface roughness from Bowers Metrology UK,
and Circular saw challenges band saws for metals from RSA Entgrat- u. Trenn-Systeme.
