Flap discs are the leading abrasives category in metal fabrication. They offer fast stock removal and supply grinding, blending, and finishing with one product, for a lower total cost. Flap discs feature cooler cutting with less gouging and burning.
Flap discs are preferred for several reasons, including lighter weight, easier-to-control, less downtime for product changes, less vibration and resulting fatigue, and also reduced noise.
Although, while selecting the flap discs for the job, it's essential to understand all the variables and how they apply to your metal fabricating application.
Selecting the right products for your metal grinding or finishing applications is extremely crucial because it will save time and price for the method.
Let's first understand a bit about flap discs.
Flap discs are constructed with multiple overlapping pieces of abrasives called 'flaps' and are an essential component of a grinder. They are designed for right angle grinder applications starting from heavy stock removal to surface blending and smooth finishing.
Flap discs are similar to emery wheels, but they yield very different results counting on the project.
Both the grinding wheels and flap discs grind metals effectively, and that they have great cut rates. However, they're costlier in comparison to grinding wheels.
They're made with an equivalent grain found in abrasives, but the grains' arrangement within the discs gives them a softer feel.
Flap discs are designed to be used with right angle grinder operations, and that they can meet your needs in several applications. While it takes a substantial amount of experience to use grinding wheels, flap discs have a smooth learning curve with a little error margin.
The abrasive material of flap discs largely determines its effectiveness; the first types are:
When choosing the three types, you would like to think about increased longevity, reduction in downtime, and inventory reduction for different products. The foremost important thing is to seek out the flap disc that meets the precise requirements of any application within the specified time and budget.
Choosing the proper grit size goes to work out how fine or coarse. The sizes range from 4 to 7 inches to suit various right angle grinders. There also are custom flap discs that are made to satisfy specialized applications. Understanding the grit sizes will ensure the simplest grinding and finishing solution for metalworking.
3. Shape of the Flap Disc
Flap discs are used on right angle-angle grinders, and that they are designed with a central point that permits work to be performed on the flaps. The flaps are often aligned at angles from 5 to 35 degrees.
Picking the proper Flap Disc shape, conical shape (Type 29), or a flat shape (Type 27) provides different performance features.
When selecting a flap disc paint removal, you ought to also consider the fabric used on the backing plate where the abrasive flaps adhere. The backing plate offers stability during usage, and it's available in the following material types:
5. The density of the flaps
With the growing innovations, flap discs are available to use on various surfaces, unlike in the past, where they were only used on metals. Today, many types of flap discs are available that will work on wood, to remove paint and concrete, and more. For every one of those applications, the foremost important thing is to settle on the proper disc to achieve the specified efficiency and effectiveness level.
