Machining cross-feed head counterweight system

摘要: A rotary machining head having a pair of dynamically balanced cross-feed slides with tool blocks mounted thereon for radial each, provided counterweight including lost motion connection and stop limiting the counterweight's radially outward movement to provide partial counterbalancing centrifugal force operating on each resisting inward feed. The permits block continue without effect, being adjustable arrest effect before any weight shift across center line occurs.
