Flap discs are designed with abrasive cloth strips glued on to a rigid backing in a fan arrangement. Flap discs can replace in many operations, both grinding wheels and fibre discs. It is possible by using flap discs to cut and finish in one operation. The unique construction allows for new grain to be constantly in contact with the surface, as the flaps continually wear out. The life of a flap disc can be 20 times that of a fibre disc, resulting in a major cost reduction in both labor and material costs. A new heavy-duty product is available which gives high performance for weld removal on corners, flame cut edges, heavy deburring and cleaning of spot welds.
When removing the left over metal from the joint area, the motion of the grinder is the same as when using the rough grinding disc. Press the face of the disc into the work and work evenly around the tubing until it appears flush with the head tube shell.
ITEMS OF FLAP DISC
Backing Plate:
Flap discs come with aluminum, fiberglass or plastic backing plates. Fiberglass is the most common. Aluminum is sometimes chosen due to no potential fiberglass dust hazards. Plastic backing is becoming more popular with some manufacturers suggesting that the plastic backing can be trimmed to increase working life.
Shape:
Flap discs are broken down into flat and angle face. Following grinding wheel terminology flat discs are type 27 while angle discs are type 29. Typical angle faced flap wheels are about 10°. Angle faced discs are more aggressive and are more suited to stock removal while flat faced discs are better on flat surfaces and will produce a more consistent finish.
Arbor:
Flap discs come either with a plain circular arbor which require a locking nut or a 5/8-11 threaded hub which allows for a quick change over.
Density:
Flap discs are available in regular and high density. High density discs, often called jumbo discs, have more flaps and are thicker. Jumbo discs tend to be a little softer and are therefore not as aggressive. Jumbo discs will last longer due to the extra abrasive.
Standard - Typical 1 / 1 flap arrangement. Provides long life and consistent rate of cut and finish.
Heavy Duty - Produced with a high stock removal in mind, these flap discs give a higher performance under tougher applications.
Jumbo - Higher stacked abrasive arrangement for improved life and durability.
