Flap discs are available in a wide range of sizes and grits and are used for applications including weld seam removal, surface blending, edge grinding and weld preparation on ferrous and non-ferrous metals.
Their main advantage over other types of abrasives in that they grind and finish in one operation, thereby, reducing both finishing time and finishing costs.
Flap discs produce very little vibration and noise during use.
Zirconia is significantly tougher than aluminium oxide abrasives which makes zirconia well suited to high pressure machining and grinding applications.
Zirconia has a good heat resistance and is commonly used in general steel fabrication for the grinding and finishing of steel, and stainless steel.
Flap wheels are ideal for stock removal, deburring, cleaning, blending and finishing in a variety of applications, including stainless steel pipe fabrication and stainless steel vessels.
A flap wheel is an abrasive wheel made from abrasive strips (flaps) radiating from a centre hub.
Bordo flap wheels come in many different diameters, widths and grits.
The outside diameter of the wheel can range from 30mm to 80mm.
Bordo flap wheels use Aluminium Oxide (Al2O3) as the abrasive material which is bonded to the strips of the wheel.
Aluminium oxide is a fused, hard synthetic crystalline abrasive.
Within the abrasive compound the Aluminium and Oxygen elements are held very close together causing these two relatively light elements to make a hard, dense crystal.
On the MOHS scale of hardness Aluminium Oxide is 9.0.
This hard crystal structure has a tendency to slowly dull or round and is hard to fracture.
