We see from your search that you're looking for information on the term "Linear Drive",
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 Advanced and well-proven linear drive systems from
DMG (UK), which we summarised at the time by saying "DMG of Luton is introducing new levels of simultaneous five-axis contouring precision in a futuristic design for machining materials as diverse as hardened steel, aluminium, copper and
graphite".
A couple of weeks before,
we featured the news release Rotary air bearing stages position precisely from
Aerotech: "Rotary air bearing stages intended for demanding high precision/high throughput applications feature a non-contact design to give a long working life and low maintenance".
In November 2007, we covered the news from Igus (UK)
concerning its DryLin ZLW-06-30 linar actuator
- take a look at Position small loads at speeds up to 2m/s
which says: "An extremely robust linear belt drive actuator weighs just 1kg, measures 1m in length and is for handling lightweight loads, is practically silent and fast running".
Take a look also at the news release from DMG (UK), CNC automatic lathes up speed, flexibility,
as well as Linear drive EDM machines 10t dies from Sodi-Tech edm,
and Five axis machining of aerospace components from Dugard.
