BLUESHARK is professional manufacturer of flap discs with more than ten years experiences, we understanding and control every step from the sanding paper selection to LAB testing. Below is the 5 important factors for choosing the right one.
SHAPE --> ABRASIVES GRIT --> GRIT SIZE --> BACKINGS MATERIALS --> FLAPS' DENSITY
1) FLAP DISC SHAPE
Flap discs are used mostly on angle grinders and designed with a backings-support which allows working to be done on the flaps-surface.
a) Type 29- Conical Style
Here the abrasives grit means the kinds coated to the flaps, there are mainly four abrasive types:
a)Aluminum Oxide – recommended for smaller jobs where a consistent, low cost product is needed.
b)Zirconia Alumina – excellent cut rate to cost ratio and good choice on carbon/mild steel applications.
c)Ceramic Alumina – latest innovative abrasives with fastest cutting as well as the best utilization of the whole abrasive grains.
d)Silicon Carbide - Universally blending, cleaning, and finishing for concrete, stone, fiberglass and other nonferrous materials (brass, bronze and aluminum, etc.)
3) GRIT SIZE
Different grit size suitable for different applications and requirements. the below table is a general guide.
The backing plate which provides stability during operation as well as flaps-combination.There are three different material types:
a)Fiberglass backing plates - most popular material because of its high strength and light weight. It's also can absorb vibration and most important is - they are consumed in same steps with the flaps.
b)Plastic backing plates - becoming more popular today due to some conformability as well as being trimmable - which allows max lifespan especially for blending and finishing. Also now days many innovative style plastic backings used such like " Spin-on" for quick change, " Radial-Ribbon" for super-cooling-stystem, etc. Anyway, the plastic backings will become more popular in future as easier processed to any shape.
c)Metal or Aluminum backing plates - good in applications demanding extra high strength and high rigid support and can be recycled. This style normally using on Silicon Carbide flap discs.
Each flaps size and total quantity of the flaps of flap discs means " Density", it's can be adjusted according to various applications. It's not absolutely more flaps with better performance.
