Creature of imagination. (Editorial).* The griffin of ancient mythology was said to combine features of two noble animals--lion and eagle. Injection-machine designers in Japan and Germany could have been inspired by that mythical myth·i·cal also myth·ic adj. 1. Of or existing in myth: the mythical unicorn. 2. Imaginary; fictitious. 3. beast when they created a mechanical cross-breed of a hydraulic and a servo-electric clamp clamp (klamp) a surgical device for compressing a part or structure. rubber dam clamp a metallic device used to retain the dam on a tooth. clamp n. . Our cover story this month discusses the real-world offspring of their impulse to join the best properties of hydraulic and all-electric machines without the disadvantages of either. In doing so, they revived an age-old argument and gave it new relevance. After half a century, machine builders are still debating the merits of toggles vs. fully hydraulic clamps. The main case for hybrids over all-electric presses (besides somewhat lower cost) is that they don't have a toggle To alternate back and forth between two states. toggle - To change a bit from whatever state it is in to the other state; to change from 1 to 0 or from 0 to 1. This comes from "toggle switches", such as standard light switches, though the word "toggle" actually refers to . This should please molders who are torn between their allegiance to fully hydraulic clamps and the desire for the "latest and greatest" all-electric machines. Those who have avoided hydraulics hydraulics, branch of engineering concerned mainly with moving liquids. The term is applied commonly to the study of the mechanical properties of water, other liquids, and even gases when the effects of compressibility are small. because they consider them slower and messier than toggles, may find that hybrids eliminate both objections. Molders' lack of familiarity with the new machines was one of the problems Senior Editor Mikell Knights faced in researching his article. There aren't many hybrid presses yet in North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. , and even fewer molders who feel comfortable comparing them with other machines. Mikell also encountered confusion about the word "hybrid." Until now, it simply meant putting an electric-driven screw on an otherwise conventional machine. But Mikell is talking about hybrid clamping clamping (klamp´ing) in the measurement of insulin secretion and action, the infusion of a glucose solution at a rate adjusted periodically to maintain a predetermined blood glucose concentration. mechanisms. These are something entirely new for processors and OEMs to argue about. By Matt Naitove, Editor |
