Variable-speed milling

  • 11-Apr-2012 05:35 EDT

The SB1028F variable-speed vertical milling machine from South Bend Lathe Co. is a 10 x 54-in machine with two power feeds and a three-axis digital readout for precise table positioning. The 5-hp, 220-V, 3-phase spindle motor operates on a single-phase power source. Electronic variable speed allows the operator to dial the perfect cutting speed. A conveniently positioned control panel features Allen-Bradley electrical components. Other features include high-precision Japanese P4 (ABEC-7) angular-contact spindle bearings, one-shot pump lubrication system for all dovetail ways, X and Y leadscrew nuts that are double-bronzed for ultra-smooth movement with minimal backlash, and recirculating coolant system with pump and reservoir in the base.

Researchers from Purdue University are studying the fundamental mechanisms behind a method that uses electrical fields to enhance ceramics-sintering processing, which could aid R&D of rechargeable lithium-ion batteries and fuel cells. The research also could shed light on a phenomenon called electromigration, which can affect the performance of electronic devices.
Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting. Variations in the way these elements solidify can yield uneven results that weaken the final product.
Improvements to Airbus A320 passenger air nozzles could potentially contribute to program-wide benefits.
NASA has selected proposals for the creation of two multi-disciplinary, university-led Space Technology Research Institutes (STRIs) that will focus on the development of technologies critical to extending human presence deeper into our solar system. The new STRIs will bring together researchers from various disciplines and organizations to collaborate on the advancement of cutting-edge technologies in bio-manufacturing and space infrastructure.
