Procedure

    1. SUBTASK 72-41-12-320-058 Machine the HP Compressor Vortex Reducer Ring Assembly Location Diameter 1006

    1. CAUTION

      TITANIUM COMPONENT - YOU MUST USE SILICON CARBIDE TYPE ABRASIVE WHEELS, STONES AND PAPERS TO DRESS, BLEND AND POLISH THIS COMPONENT.

      CAUTION

      TITANIUM COMPONENT - MAXIMUM SPEED FOR MECHANICAL TOOLS MUST NOT EXCEED 1000 REVOLUTIONS PER MINUTE.

      CAUTION

      TITANIUM COMPONENT - YOU MUST MAKE SURE THAT WHEN YOU REMOVE MATERIAL, BLEND AND POLISH, TO MAKE SMOOTH, THAT NO SPARKS ARE PRODUCED.

      CAUTION

      TITANIUM COMPONENT - IF THE MATERIAL SHOWS A CHANGE IN COLOR, TO A DARKER THAN A LIGHT STRAW COLOR, THE COMPONENT IS TO BE REJECTED.

      CAUTION

      TITANIUM COMPONENT - AVOID BUILD UP OF HEAT BY APPLYING ONLY GENTLE PRESSURE AND KEEPING THE TOOL SPEED AS LOW AS POSSIBLE. USE TECHNIQUES WHICH ALLOW FOR PROGRESSIVE WEAR OF THE DRESSING MEDIA TO PRESENT A CONTINUALLY FRESH CUTTING SURFACE TO THE WORK PIECE.

      CAUTION

      DO NOT DWELL ON ONE AREA OF THE COMPONENT.

      CAUTION

      DRESS, WHERE POSSIBLE, IN A CIRCULAR MOTION, TAKING LIGHT CUTS TO AVOID OVERHEATING.
