2" x 60" Surface Conditioning Belts (Non-Woven), 6 PACK

Pedestal belt grinders in the 2" x 60" class, the Burr King 760 and BUR77110 and the Kalamazoo BG260HV our original listing named, are production machines, and this is the belt that does their finishing work. After a zirconia or ceramic belt has knocked a weld down, a 2" x 60" non-woven belt blends the ground zone into the parent metal, strips the heat tint, deburrs the edges and leaves a uniform satin on stainless, steel, aluminum and titanium without changing the part.

The 60" loop carries a lot of web, so it runs cool and lasts through long deburring shifts. We convert them in Anaheim, California and pack six of one grade per box in Coarse (brown), Medium (maroon), Very Fine (blue) or Ultra Fine (grey).

• Fits Burr King 760 and BUR77110, Kalamazoo BG260HV and other 2" x 60" belt grinders
• Aluminum oxide grain in a nylon web: blends and deburrs without removing measurable stock
• Coarse, Medium, Very Fine and Ultra Fine, 40-60 through 320-400 grit finishes
• Long 60" loop stays cool and lasts through production deburring
• Resists loading on aluminum, plastics and stainless; no glazing like a coated belt
• 6 belts per pack; free shipping on orders over $200

Which grade should you run on a 2" x 60" pedestal grinder?

Grade selection on a production grinder comes down to what the coated belt left behind and what finish the part ships with.

• Coarse (brown, 40-60 grit equivalent): mill scale, rust and heavy burrs on hot-rolled and sawn stock, weld spatter, old coatings on parts coming back for rework. The only grade that removes noticeable material; keep it moving on thin sheet.
• Medium (maroon, 80-120 grit equivalent): the production grade. It blends the 80-120 grit scratch from a coated belt into the surrounding surface, removes heat tint from stainless welds, breaks edges on machined and laser-cut parts and evens a steel weldment before paint or powder coat.
• Very Fine (blue, 180-240 grit equivalent): the #4-style directional satin used on food-service, pharmaceutical and architectural stainless, and a clean uniform finish on aluminum and titanium. Use after 150-220 grit coated.
• Ultra Fine (grey, 320-400 grit equivalent): the finest satin and the last belt before a buffing wheel, and the grade for aluminum going to anodizing. We are one of the few converters offering it in belt form.

A typical stainless fabrication sequence: coated 80 grit to level the weld, coated 120 or 150 to refine, Medium non-woven to blend and clean, Very Fine along the grain to match the sheet. For steel headed to powder coat, stop at Medium.

Grit guide: grade, colour and equivalent finish

These numbers describe the scratch the web leaves, not its removal rate. A non-woven belt cuts far slower than a coated belt of the same number, which is why it blends a ground weld into the parent metal instead of digging a new low spot.

Which machines take a 2" x 60" belt?

• Burr King 760 and Burr King BUR77110 2" x 60" belt grinders, named on our original listing.
• Kalamazoo BG260HV 2" x 60" belt grinder, also named on our original listing.
• Other 2" x 60" pedestal and bench belt grinders used for deburring, weld blending and tool finishing.

Confirm the length: 2" x 48", 2" x 60" and 2" x 72" are all common grinder belts and they do not interchange. Mounting: release the tension, slip the belt over the contact wheel and drive wheel with any direction arrow on the inside pointing the way the belt runs, re-tension and adjust tracking until the belt runs centred. The web is thicker than cloth, so a small tracking correction is normal after switching from a coated belt. Other sizes are made to order in about three days.

How to get the most out of it on a production grinder

1. Drop the speed where the machine allows. Variable-speed grinders should run non-woven well below coated-belt speed. On a fixed-speed pedestal grinder, compensate with light pressure and short contact times.
2. Light to moderate pressure. Industrial grinders make it easy to lean in. Do not. Heavy pressure folds the web, heats the part and strips the belt in minutes; light pressure gives the long life these belts are bought for.
3. Use the contact wheel for blending, the platen for satin. A weld zone blends best on the wheel; a flat panel or bar gets its even directional satin on the platen.
4. Move in one direction. Draw the part along its length in overlapping strokes. Dwelling leaves a bright patch and cross strokes show on stainless.
5. Come in from 120-220 grit. Non-woven refines the last coated scratch; it will not remove 36-60 grit marks or a raw weld bead.
6. Lubricate lightly on aluminum. A trace of oil or wax stops soft alloys smearing into the web. Run steel, stainless and titanium dry.
7. Store belts hung or loosely rolled, away from solvent, sunlight and damp air, and let cold belts warm before running them.

Use it for / don't use it for

Use it for

• Blending ground welds into stainless and steel sheet, tube and bar
• Removing heat tint, mill scale, light rust and spatter from fabrications
• Edge breaking and deburring machined, sawn and laser-cut parts without changing dimensions
• #4-style satin finishing on food-service, pharmaceutical and architectural stainless
• Prepping steel and aluminum for paint, powder coat, plating or anodizing
• Finishing plastics, fiberglass and non-ferrous alloys without loading

Don't use it for

• Weld removal or stock removal; that is a zirconia or ceramic coated belt's job
• Removing coarse scratches from 36-60 grit belts
• Producing a mirror; go from Ultra Fine to a buffing wheel and compound
• Heavy pressure or dwell, which tears the web and blues stainless
