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