DISTRIBUTOR FOR AUTOMATIC CONTROL SYSTEM OF CONICAL PART FINISHING MACHINE Russian patent published in 1996 - IPC

FIELD: machine tool manufacture. SUBSTANCE: distributor has casing with supply and discharge union positioned on outer surface of casing. Conical slide valve with grooves is mounted within casing. Grooves are positioned in pairs along slide axis. Each groove is positioned below pair of unions to form concentric row in slide valve section. Each subsequent pair of grooves is offset with respect to previous pair of grooves for distance equal to union spacing. Distance between grooves in each concentric row is defined by minimum time required for rotational motion. Length of each groove is determined by spindle vibrational amplitude value. EFFECT: increased efficiency and improved precision of finishing machine. 2 dwg
