We see from your search that you're looking for information on the term "Dimensional Tolerances",
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 Coated roller chains take high loads from
Iwis-Flexon, which we summarised at the time by saying "Roller chains are coated to significantly reduce the surface coefficient of friction within the chain link and offer a high load bearing capacity, wear-resistance and resistance to
chemicals".
A couple of weeks before,
we featured the news release Mill-turn centre does jobs in one set-up from
Colchester-Harrison: "A mill-turning centre with a sub-spindle has taken multi-operational work away from a conventional CNC lathe and machining centres to finish jobs complete in a single set-up, said a subcontractor".
In June 2007, we covered the news from Leader CNC
concerning its Kitamura Mycenter 3Xvertical machining centres
- take a look at VMC with advanced CNC saves 40% on machining
which says: "Using a vertical machining centre's 15,000 rev/min spindle and the advanced look ahead features on its CNC, a company is realising 40% savings machining 3D profiles in advanced alloys".
Take a look also at the news release from James Walker Keaflex, Brochure from elastomer engineering specialists,
as well as Portable CMM for production floor efficiency from Faro UK,
and Smallest backlash-free precision gears from Harmonic Drive UK.
