MJC Engineering is a custom machine tool builder in Huntington Beach, Calif., specializing in metal-spinning machines for sheet spinning, flow forming, wheel spinning and others. MJC machines typically use large volumes of hydraulic power in operation. About three years ago, the president at MJC, Carl Lorentzen, began investigating the configuration of the hydraulic units used…

A hydraulic pump directly coupled with a servomotor delivers highly dynamic performance, often with sizeable energy savings. Machine-tool manufacturer Lasco Umformtechnik, based in Coburg, Germany, is taking advantage of such servo-electric pump drives in its latest solid and sheet-metal forming presses. Lasco recently delivered a deep-drawing press supplying 800 tons of force at up to…

Combining hydraulic pumps with variable speed drives increases efficiency while reducing noise and environmental impacts. With any fluid power system, efficiency is always top of the mind, so components and advanced technology that can improve energy consumption are increasingly necessary. To that end, the NFPA last year commissioned a survey to examine the current and potential…
