Abstract
A table (1) revolving intermittently and carrying on its periphery piece-holder grips, has central openings (11), which make possible the discharge of working shavings and wastes at the center of the table itself (arrow 12) and not at the periphery (arrows 7, 7') as now is done. This makes possible direct discharge of the working shavings and wastes in the collection container underneath and avoids clogging and stopping of the machine for cleaning which requires the presence of additional labor and limits production. Nozzles (13, 13') direct fluid radially inwardly to assist in this central discharge of shavings and wastes.
Claims1
In a machine tool having a multiplicity of work stations arranged about the periphery of an intermittently rotating work-holding table;
- the improvement in which the table comprises a peripheral circular crown, a central hub, a plurality of spokes interconnecting the crown and the hub and leaving spaces between the spokes, a plurality of work-holders on the crown radially outwardly of said spokes and spaces, and nozzles adjacent the periphery of the table so arranged as to direct jets of fluid radially inwardly across the upper surface of said crown to force material removed from work pieces radially inwardly to be discharged downwardly by gravity through said spaces.
