PURPOSE:To improve working efficiency by a method wherein a work, not worked yet, and another work, whose primary working is finished, are clamped in series so as to pinch them and the work not yet worked is inserted from one end of the loader, for transferring the worked work, while the work, whose secondary working is finished, can be discharged from the other end of the loader. CONSTITUTION:Two pieces of the works W, being pinched by clamp shafts 4, 35, are worked by primary and secondary working grindstone wheels 31, 32 respectively, thereafter, a locating device 28 is operated and the works are indexed to the position of given angle about the axial line of main shafts 3, 6. Next, the locating device 28 is released and two pieces of the works W are inserted into the holding part of a loader arm 40 at a transport position B by the operation of an advance and retreat driving device 19 under pinching by the shafts 4, 35. Subsequently, the loader arm 40 is rotated by 180 deg. to transport the works W which are already worked to a supplying position while the works, not worked yet, are pushed out of the main body of a stock at the supplying position. Thereafter, two pieces of works W are returned to the original position and the same working are effected. |
