Belts and Application: Abrasive Product Spotlight

Belts are used in multiple applications from fine finishing of stainless steel coil to heavy stock and weld removal. In general heavy weight Y-weight are used for stock removal whilst flexible J-weight is used for fine finishing and contour work. In fact J-weight materials are not available in coarse grits coarser than 60.

Resin Fiber Discs on Mild and Stainless Steel

Resin Fiber Discs are a flat disc used for heavy grinding and weld removal. They are used for similar applications as Flap Discs. Resin Fiber Discs consist of a stiff fiberboard backing coated with a single layer of resin and abrasive. ARC’s Resin Fiber Discs have grinding aids in both the AO and ZA products. This grinding aid helps performance and keeps the disc cooler during grinding. The discs have an arbor hole to allow them to be attached to a back-up pad which they are always used with. We recently created a case study of our discs on mild steel and stainless steel against top competitors that give very powerful insight with the performances.

Flap Wheels: Abrasive Product Spotlight

Flap Wheels are available as mounted or un-mounted products. Mounted flap wheel are generally 3” or less in diameter and are used on portable tools. Unmounted flap wheels are 4” and larger in diameter and the larger wheels are used on stationary tools.

Flap Wheels are designed for light finishing, deburring and flash removal. The flap design allows the wheel to contour around the work piece and smooth the surface. As the flap wears away new abrasive grain is exposed and the wheel continues to cut.

Flap Disc Tests on Stainless Steel

For stainless steel, PREDATOR™ Flap Discs provide extremely fast weld removal combined with superior life compared to all other Flap Discs in the market. PREDATOR™ is well suited for all mild steel, high alloy, nickel alloy and stainless steel. In regards to Zirconia and Aluminum Oxide, The structure is meta-stable and under heat and/or pressure the structure fractures producing new cutting edges. This gives the grain a longer cutting life and is especially suited to coarser stock removal applications typically 24 to 80 grit. It is a more expensive grain but the improved performance usually outweighs the cost. We go more in depth on the dynamics of our PREDATOR™ and Zirconia test results, which can be read through this case study.
