Abstract

The present invention realizes bar material processing with higher accuracy by reducing vibration during bar material processing. In this processor, a fixed pipe extended in a main shaft pipe to receive a bar material to be processed is provided, and a feed arrow of a bar material feeder is received in the pipe to feed the bar material. When the feed arrow is located in the fixed pipe, a center axis of the bar material is located on a center axis of the main shaft. The center axis of the fixed pipe is arranged to be deviated to an upper side from the center axis of the main shaft so that a lower surface of the feed arrow may be moved along a bottom surface at the inside of the fixed pipe.

Description

technical field [0001] The present invention relates to a bar processing machine for processing a bar fed by a feeding part of a bar feeding machine, and more particularly to a bar extending in a spindle having a fixed tube for receiving the bar to be processed processing machine. Background technique [0002] In the current bar processing machine, as shown in Japanese Patent Publication No. 53-22716, for example, a fixed pipe for receiving the bar is provided in the main shaft (tubular main shaft 2) of the spindle frame for rotating the bar to be processed. (spacer 3) form. Both ends of the fixed pipe (spacer member 3 ) described in the above publication are supported by bearing members or the like. [0003] In the current bar processing machine, the central axis of the fixed pipe coincides with the central axis of the main shaft of the bar processing machine (machining axis of the bar), and the central axis of the feed member (feeding arrow) also coincides with the above...
