4) ADDITIONAL INFORMATION: 

a) BLUESHARK produce flap discs with different backing plate:

*Fiberglass backing plate - Most popular and it's can reduce vibration and is consumed together with the flaps. High strenghth with light weight.
*Plastic backing plate- With very nice lookings and is trimmable to increasing service life. The ABS plastic backing with very high strength and supply mas safe working performance.
*Nylon - Very familiar with plastic backings but with more light weight.
*Metal HUBS: provides extra high strength and rigid support as needed and normally using for heavy task . Also it can be recycled. 

b) 100% Germany original ceramic abrasives materials. 

c) Grit size recommendation

    40#--Aluminum ,Unalloyed and low-alloy steels,low-strength stainless steel

    60#--High-alloy,stainless steel,high-temperature and heat-treated steels

    80#--High-temperature alloys

   120#--For especially smooth steel finishes(refine polishing)    

d) Best working angles

     (15~30')                               (0~15')

For best performance , keep 15~30' when grinding and 0~15' while polishing & finishing.    

e) If using flap discs replace fiber discs workings, you should choose one grade coarse grit size. Such like you should using 80# flap discs if normally using 60# fiber discs.  

G.Ratio - Absolutely Index of Flap Discs performance???

BLUESHARK manufacturer many style flap discs. If classified by abrasives grain, there are four kinds - aluminum, special " Heat-Treated" Alo, Zirconia and Ceramic.  We collected many customers feedback and found it's not absolute views even the same discs.   

As well known, G.Ration is the most important index to measure a abrasives wheels for grinding applications.

G.Ratio = ( A1-A2)/(B1-B2)    

A1= Work-piece weight before grinding          A2 = Work-piece weight after grinding

B1= Flap discs weight before grinding             B2 = Flap discs weight after grinding

Normally we testing flap disc at least 30 minutes non-stop grinding.

General saying, this parameter more big , the flap discs with higher performance in first view . But the hand-feeling, working pressure, etc also need considering.  

For example, A flap discs remove 100g work-piece and itself weight reduce 5g, the G.Ratio is 100/5=20.  B flap discs remove 200g work-piece and the discs' weight reduce 20g, the G.Ration is 200/20=10.  If we can say A is better than B ? The answer is Not absolutely!!!  As B remove 2 times work-piece than A and with much higher grinding ability, if considering labor cost, B maybe more economic than A.

Meanwhile the flap discs lifespan is also another index when measure performance.  BLUESHARK willing always listen customers' voice and try our best provide most suitable abrasives solution for everyone.  You name it , we make it !!!

How to choose correct flap discs ?

 

As well known, there are many style flap discs in the market nowdays due to the non-copy advantages such like: lighter weight, easy control, less vibration & dust, grinding, blending and finishing with one product, etc . Absolutely we can take max benefits afforded by flap discs If understanding well all the variables and how they apply to your grinding & polishing workings.

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  

This type with angled flaps and may be used on both contoured and edge work. The angled flaps  provides max attaching area between abrasives with work-pieces and best choice for aggressive stock removal.  

       b) Type 27 - Flat Style 

This style ideal for finishing and mainly used on flat surfaces. They are the best choice for blending and smooth finishing.

2) ABRASIVE GRIT

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.

4) BACKING-PLATE MATERIAL

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.

5) ABRASIVE FLAP DENSITIES

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. 

Above is the outcome of testing between Blueshark TURBO & normal density line with grinding 10 minutes of stainless steel #304. The both flap discs with 40# grit size. General saying, more flaps more lifespan, less flaps less heating. BLUESHARK supply different density flap discs to meet all of your requirements, also the customer can specify the flaps size and quantity if needed.
