Zirconia Flap Disc

Introduction: Kungfu Eagle can provide zirconia flap discs of 4", 4.5", 5”, 6", 7" and with additional specifications. We can also customize different sizes according to customers' actual needs. Our zirconia flap disc is made up of a fiberglass backing plate and abrasive cloth of zirconia alumina combined with glue. Zirconia alumina is a taupe artificial corundum smelted by high temperature in an electric arc furnace with alumina and zirconia as raw materials. It has a tough texture, good fire resistance and high grinding rate, so that the flap disc made of zirconia alumina can be used to grind iron, stainless steel, glass, stone, etc. We use a fiberglass backing plate, and the main material is a glass fiber matrix, which has the characteristics of imperviousness to glue, high strength and good toughness. The fiberglass mesh used in the backing plate is more than five layers thick, which can make it possible for the product to work in harsh environments without breaking.

Application
Kungfu Eagle’s zirconia mop disc can be used for grinding welding joint and deburring of workpieces like metal, stainless steel, carbon steel, copper and aluminum, also for grinding and polishing glass and stone. Compared with the plastic backing, the fiberglass backing zirconia flap disc is safer, so it is recommended for high-strength industrial applications, such as metal manufacturing and construction industry.

Features

1. Zirconia alumina has the characteristic of fast heat dissipation; thus, it can effectively prevent the workpieces from burning.

2. The flaps on the sanding disc is fully automatic overlapped by the machine, and the workmanship is neat and smooth.

3. We use zirconia alumina as the raw material of the mop disc, which has twice the sharpness and abrasive resistance of ordinary calcined sand. Meanwhile it improves the protection of the polished products.

4. The flap can be widened and thickened. For example, for a 4-inch flap disc, the general number of flaps is 72, with the length of 22mm and the width of 14mm. When the customer requests the number of flaps to be added to 80, the length and width of the flap can also be increased, usually 2-3mm is the most suitable. And the abrasive resistance can be increased by 50%.

Custom zirconia flap discs:

1. Shape:
T27 flap disc (flat, suitable for normal flat objects, such as straight steel plates);
