Manufacturing device for spool

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic control valve spool processing apparatus, and in view of the fact that the removal of burrs on the land edge of the spool is not easy in the grinding process after the conventional processing, the removal of burs generated on the spool is perfectly performed. Hydraulic control valve spool processing apparatus that can be made. The present invention is a vertical conveyance of the conveying conveyor, the feeding means for raising the completed spool on the conveying conveyor, the conveying roller for conveying the spools loaded on the conveying conveyor, and the spool conveyed from the conveying conveyor A hydraulic control valve spool includes a vertical brush for brushing in a direction and a horizontal brush for longitudinally brushing a spool conveyed from the conveying conveyor.
