We see from your search that you're looking for information on the term "Power Chuck",
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 Swivelling, rotating table has high accuracy from
Deckel Grinders, which we summarised at the time by saying "A trunnion mounted swivelling and rotating table, which has temperature regulated to +/-0.25 deg C, can achieve workpiece accuracy to within three seconds of arc".
The same day,
we featured the news release Bar feeder matches CNC automatic needs from
Kitagawa Europe: "A bar feeder is designed for the fast feeding of bars from 0.8mm to 12.7mm, including matching the high acceleration rates and high spindle speeds of CNC automatic lathes".
In December 2007, we covered the news from Pratt Burnerd International
- take a look at Chucks and collets add on 'solutions' service
which says: "Manufacturers of workholding equipment, such as collets and chucks, are now having to offer 'solutions' with production engineering know-how, and not just products".
Take a look also at the news release from Schunk Intec, Tool and work holding equipment sales up 27%,
as well as Compact bar feeder fits restricted spaces from Kitagawa Europe,
and 6-jaw power chuck offers machining accuracy from Schunk Intec.
