How To Mirror Polish Outer Tube Joints – Step 1: Preparation
Abrasive tip: Setting your machine speed between 3000 and 4000 RPM will avoid burn marks on your workpiece and maximise disc life.
Dress the grit of your new RCD by grinding a test piece of stainless steel. If you miss this step, the disc will be too aggressive on first use.
How To Mirror Polish Outer Tube Joints – Step 2: Sanding The Weld
Move the RCD/ME/125 back and forth in the longitudinal direction of the tube, ensuring that the sanding lines follow the circumference of your workpiece.
Work at an angle of 10 to 15 degrees whilst applying light pressure equal to the weight of your machine.
Sand up to the area where the two tubes meet at the highest point – the corner should be sharp and round.
Once satisfied with this result, repeat on the other side.
Then, repeat with the RCD/VF/125.
How To Mirror Polish Outer Tube Joints – Step 3: Erasing Grinding Lines
At this point in the process, there may be visible grinding lines and surface scratches on your workpiece – these can easily be removed using Cibo’s unitised discs.
Now, sand in a perpendicular direction to that of the RCDs and continue until any surface damage has been erased.
How To Mirror Polish Outer Tube Joints – Step 4: Mirror Polishing
Allow the disc to turn against the PV/102 pink polishing compound until it is fully coated.
Use the disc in a longitudinal direction (opposite to that of the SAG disc) and polish until the desired mirror polish finish is achieved.
How To Mirror Polish Outer Tube Joints – Step 5: Cleaning Up
Completing this step will remove any grease from the stainless steel without the risk of surface scratches.
