A technician at a plant that uses large three-axis milling machines explained that one of the machine’s hydraulic power units had foam coming out of the reservoir’s filler breather and the HPU was quite noisy. He observed the foam oozing out when...

Organizers introduce general commissioner and information about the event.

For large machining centers, balancing the weight of spindle heads and workpiece tables saves energy — and, therefore, money. Hydraulic weight balancing is an automatic process and takes advantage of the fact that once a system is pressurized...

Aluminum parts producers are carefully assessing the performance of their extrusion presses as customers such as vehicle component manufacturers, aerospace suppliers, window and door (fenestration) suppliers and other high-volume users seek faste...

The first annual Motion, Drives and Automation Conference — Fluid Power in Automation track —  was held at IMTS September 10 and 11, 2012, sponsored by Bosch Rexroth Corp. and presented by Hydraulics & Pneumatics and Machine Design magazines, as ...

It’s a given that when you need to transmit tremendous forces for excavators and other types of heavy equipment, hydraulics is the only way to go. And although transmitting cylinder force to the machine’s structure may not be a “hydraulics” probl...

When air, vapors, or light materials must be moved easily and inexpensively, air amplifiers provide a simple solution. These devices use the Coanda effect — the tendency of a fluid stream to be attracted to a nearby surface — to create air mot...
