There are a number of buffing wheels you can use on an edgebander
1. Cloth- great for PVC, ABS, and similar materials. Cloth will bring a little bit of the sheen back to the edgebanding and with the introduction of release and cleaning agents can do a light clean up of glue from the panel surface.
2. Sanding wheels- Can be used for veneers and wood strips.
3. Scotch Bright- Most commonly used for HPL. Its more aggressive then cloth and can provide a better finish on the HPL edges.
4. Buffing wheels for textured/structured panels- These are used, as the description indicates, for textured or structured panels. Sorry I can't provide the material these are made of. Ott edgebanders are the only ones that have them and of course I won't divulge too much about them. It's nice to keep this innovative station and the advantages of it as an Ott only feature. I'll provide the link to a 10 second video of them in action.
It's also important to take notice of the various sprays that can enhance your edgebander, and particularly the buffing stations. Ott uses 4 different sprays as described below. The release and cleaning sprays can be found on most any edgebander these days.
1. Release agent- on Ott edgebanders this is applied before the premill station. This is done before the pre-mills so the edge will be cleaned and there is no spray on the edge of the panel where the glue is applied. If spray is on the edge that glue is applied to it will help keep the glue from sticking to the panel.
2. Cleaning agent- applied just before the buffing wheels to assist in cleaning excess glue from the panel surface
3. Anti-Static spray- to reduce edge trimming static electricity that causes trimmings to stick to the panels.
4. Slick agent for easy to scratch edges- helps avoid damage to the applied edge.
