      2. Vibro-polish the VSV airfoil and adjacent annulus surfaces. Prepare the component for inspection.

      1. Refer to the SPM TASK 70-38-25-380-501.

        The surface finish is to be 32 microinches (0.80 micrometers).

        Do not have more than five VSV for one cubic foot of the superpolishing media.

        Use vibro-polish facility.

        Use one of the superpolishing media and one of the liquid compounds given below:

    5. SUBTASK 72-41-32-380-013-B00 Vibro-Polish the Stage 4 VSV Airfoil, Assembly B

      CAUTION

      THIS VSV IS A GLASS BEAD PEENED COMPONENT. DO NOT ABRASIVE BLAST THE VSV.

    1. Refer to: Figure.

      2. Vibro-polish the VSV airfoil and adjacent annulus surfaces. Prepare the component for inspection.

      1. Refer to the SPM TASK 70-38-25-380-501.

        Polish the surfaces in the area specified AB as given in the procedure.

        The VSV airfoil is to have a surface finish of 16 microinches (0.40 micrometers) on a minimum of 70 percent of the surface area.

        On the remainder of the VSV the surface finish is to be between 16 microinches (0.40 micrometers) and 32 microinches (0.80 micrometers).

        Do not have more than five VSV for one cubic foot of the superpolishing media.

        Use vibro-polish facility.

        Use one of the superpolishing media and one of the liquid compounds given below:
