Document Type and Number:
WIPO Patent Application WO/2015/041084
Kind Code:
A1
Abstract:
Provided is a rod-material supplying device and a numerical controlled machine tool equipped with the rod-material supplying device, wherein even if the driving force of a motor is insufficient, a rod material can be chucked. The present invention is provided with the following: a pressing arrow (60) having a finger chuck (61) on the tip thereof; a pressing arrow-use servo motor (74) and an air cylinder device (80) that cause the pressing arrow (60) to move forward and back in order to move a rod material (200) in or out of the finger chuck (61); and an NC control device (90) that controls the driving of the pressing arrow-use servo motor (74) and the driving of the air cylinder device (80). The NC control device (90) controls the driving of the pressing arrow-use servo motor (74) and the air cylinder device (80) so that when the rod material (200) is being moved in or out of the finger chuck (61) the pressing arrow (60) is caused to move together with the rod material, and the NC control device functions as an error allowing means that allows errors in the operation amount of the pressing arrow-use servo motor (74) when the rod material (200) is being moved in or out of the finger chuck (61).
