Pre-polishing plastic media – grinding, deburring – with a smooth flat surface finish – 15mm cone RKH/4
Rumbling / tumbling / vibratory finishing you need to use media – when working with Aluminium its best to use a Plastic media. This is a Pre-polishing plastic media.
pre-polishing plastic media for aluminium and other softer metals for:
- edge breaking
- surface finishing
- cleaning of casting
- preparation of metal prior to polishing.
15mm cone is a good size which will allow good movement in most machines. Depending on how complex your aluminium part is the 15mm cone should reach into all the gaps and holes you require action. This media will leave a bright but mottled surface finish.
We recommend that you fill your vibro machine right up tot the top of media so that you maximise weight and mass on the aluminium part. This will stop any pecking of the media on the part and will leave the best results. Use plastic media for aluminium with a liquid compound for corrosion protection and to enhance the surface finish.
This pink cone is excellent for grinding but leaving a good surface finish so like using 80 grit wet and dry but leaving a 1200 grit finish. Polishing after using this media is much quicker and easier and will leave great bright results.
After using this media we highly recommend using:
- Porcelain pins for a wet polishing process – also use with FC120 compound for a brighter finish.
- walnut shell for a dry polishing process. this normally has polishing paste in it.
