PURPOSE:To enhance the work efficiency by a method wherein burrs at the weight part and shaft part are removed by belt-grinding under clamped state and profile milling during rotating in the deburring device for the crankshaft of a compressor. CONSTITUTION:The crankshaft 1 to be deburred is placed on the V-grooves 9 of holders 10 in order to intermittently run in order by means of a conveying apparatus. When three shafts 1... face opposedly to a first belt-grinding device, the shafts 1... are pressed down by means of clamping fixtures 19 and an abrasive belt is forwarded in order to simultaneously remove the burrs (c) at the end surfaces of the shafts 1... by grinding. After that, the burrs (b) at the weight parts 2 of the shafts 1... are simultaneously removed by grinding similarly at a second grinding device. Next, when one shaft 1 out of the three shafts faces opposedly to a turn-giving device 30, the shaft 1 is lifted up on elastic rollers 35 and 35 with the extension of a cylinder 32 and brought into contact with a driven roller 38, which contacts with a driver roller 37 so as to be rotated in such a manner that a grinding wheel 42, which rocks itself by gravity and at the same time rotates, profile milling the outer circumference of the weight part in order to remove the burrs (a). |
