Choosing Polishing Compounds

Finish Type

You need to pick the right polishing compound for your finish. If you want to get rid of deep scratches, start with a Tripolis compound. This compound helps take away marks and makes the metal smoother. Use an intermediate compound if you want a satin or semi-gloss look. For a mirror polish or high shine, use a finishing rouge. This last step makes the metal very shiny and bright.

• Think about your goal:

• Deburring: Use a cutting compound to take off rough spots and scratches.

• Polishing: Use an intermediate compound to smooth the metal and make it shinier.

• Burnishing: Use a finishing rouge for a mirror or high shine.

The size of the abrasive media is important too. Small media give a smoother finish but take more time. Big media remove scratches faster but may not make the metal as smooth.

Machine Compatibility

Your polishing machine helps decide which compound is best. Fixed buffing wheels like sisal or cotton work well with bar compounds. Vibratory or tumbling machines usually use paste or liquid compounds. Some machines need compounds that clean or stop rust. Always use the right compound form for your machine to get the best shine.

Tip: Wet tumbling compounds work well with vibratory machines. They help clean, polish, and protect your stainless steel.

Stainless Grade

Different stainless steel grades polish in different ways. Grades like 304 and 316 have special features. For example, 316 has more chromium and molybdenum. This helps it fight rust and gives a better shine after polishing. The table below shows how the metal changes after polishing and how it affects the look:

You get a better mirror and shine on 316 after polishing because of its chemical mix. Always check your stainless grade before picking a compound.

Compound Form

Polishing compounds come as bars, pastes, and liquids. Bars are best for buffing wheels and taking away scratches. Pastes and liquids work well in vibratory or tumbling machines. Some compounds have extra chemicals to clean or stop rust. Pick the form that fits your machine and the finish you want.

• Bar: Good for buffing wheels and taking away scratches.

• Paste: Works well for small parts and detailed polishing.

• Liquid: Best for big batches in tumbling machines.

Remember: The right compound and form help you take away scratches, polish the metal, and get the shine or mirror finish you want.

Polishing Machine Process

Step-by-Step Polishing

You can get a perfect finish on stainless steel by following simple steps with your polishing machine. First, clean the metal to take off any dirt or oil. Use a coarse buffing wheel and a cutting compound to remove deep scratches fast. Move the machine slowly and evenly over the metal. Next, use a medium buffing wheel and compound to get rid of marks left from the first step. For the last polish, use a soft buffing wheel and a fine compound. This step makes the metal shiny and smooth. Wipe the metal between each step so grit does not scratch it. At the end, use a clean cloth to make the metal look bright and like a mirror.

Tip: Pick polishing wheels that go with your compound for the best shine.

Safety Tips

Be careful when using a polishing machine. Wear safety glasses and gloves to keep your eyes and hands safe from flying bits. Make sure loose clothes are tucked in and tie back long hair. Place the polishing machine on a flat, steady surface before you start. Keep your hands away from the spinning buffing wheels. Always turn off the machine before you change wheels or compounds.

Common Mistakes

Many people make mistakes that hurt the final look. Reports say common problems are:

• Wrong machine setup causes size mistakes

• Bad polishing or buffing makes the surface look bad

• Rough handling or cutting causes edge problems
