PURPOSE: To facilitate placing of the work and to improve the accuracy and reliability of measurement by changing an analog operating system to a digital operating system thereby permitting easy execution of automation.
CONSTITUTION: The work 3 on a pallet 1 is first transferred by a transfer device 7 onto the measuring part 4 of a Pos. 2 by which the unbalance thereof is measured. Then the work 3 is transferred again by the device 7 onto the NC correcting and working part 5 of a Pos. 3, where an angle is indexed and the work is corrected and worked in accordance with the results of the measurement in the part 4. Again the work 3 is transferred by the device 7 to the inspecting part 6 of a Pos. 4, where the residual quantity of unbalance is measured, and whether the work is corrected and worked in the range of the prescribed permissible quantity of unbalance or not is judged. The work 3, the inspection of which is completed, is finally transferred onto the pallet 1 again by the device 7. Thus the work 3 is fed progressively to the Pos. 1WPos. 4 and is subjected to measurement-correction-inspection, whereby the correction of balance is completed.
