Vertical turning lathe

  • 24-Nov-2010 02:32 EST

A vertical turning lathe from DS Technology can be configured with milling and grinding capability, robotic tool exchange, automatic pallet change, and other features to bring the benefits of unattended, single-hit machining to the production of very large workpieces. Called TVU, the machine is manufactured by DS Technology group member, Berthiez, at its factory in St. Etienne, France. The unit can be used for applications such as turning jet engine components and mold and die machining and turning of large wheels. The turning-milling-grinding center is based on a compact, stiff, cast-iron structure of thermo-symmetrical design with integral temperature compensation. Configurations include either high speed, with 630-800 rpm table for workpieces up to 3.5 t; or heavy load, with 220-500 rpm table capable of supporting 20-t components. Drive to the table, which can be up to 2.5 m in diameter, is via a two-stage gearbox and backlash-free chain.

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.
