Flat surface machined into the shank of a cutting tool for enhanced holding of the tool.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
A line of interleaf flap discs that utilize two separate abrasive materials to remove small welds and create a grained-in satin finish in one operation are available from Rex-Cut Abrasives.
Rex-Cut FUSION flap discs consist of a premium coated abrasive layer and a non-woven surface conditioning layer thatare combined into one disc, which can remove light welds and produce a grained-in finish on stainless steel. Eliminating the need for multiple grinding operations, they save operator time, run smoothly, and create a uniform satin finish in one step.
Providing controlled material removal, the flap discs constantly reveal fresh abrasives as they work and typically last up to six times longer than traditional surface conditioning discs, claims the firm. Suitable for flat or contoured surfaces, they are available in 4-½"- and 5"-dia. sizes and come in coarse, medium, and fine grits.
The flap discs are priced from $12.70 per box of 5 (4-½").
