<p>The present invention relates to a shaft processing device comprising: a pair of side units (221) having a hole-shaped collet hole (222) and a cutting portion (223); a pair of taper units (224) having a slope (225); a collet unit (220) linked to a collet rotation motor (248) to be rotated; a pair of inner assemblies (241) coupled to enable an inner circumferential surface to surround the slope; and an assembly unit (240) having a pair of outer assemblies (243). One end part and the other end part of a shaft is putted into the collet unit, and the collet hole is retracted to enable the shaft to be fixated to the collet unit, and both end parts of the shaft is abrasive machined by a polishing machine. According to the present invention, the shaft processing device significantly improves a processing quality with respect to the shaft.</p> |
