Tool stand of nc automatic lathe

Abstract

Abstract PURPOSE:To decrease a time of uncutting process of a tool as short as possible when it is selected, by permitting the selected tool to once reach an advance start position of the tool then advance to its cutting point so as to feed the tool in its cross feed direction. CONSTITUTION:A tool 21c, if it is selected, is fed by a quick traverse to a tool advance start position then approximated in a quick traverse to a position in the vicinity of a cutting point by a pulse motor. Next, feeding the tool to cut a workpiece to its prescribed machining size, a main spindle advances to perform cutting work. If the cutting work is finished, the tool 21c is returned to the tool advance start position, and the next tool is selected and fed to its advance start position by a quick traverse.
