What is the most important factor of best flap discs?

Blueshark manufacturer different abrasives flap discs, from the Alo to Ceramic sanding paper with fiber backings, plastic backings.etc. In our views, the best flap discs most important factor is the abrasives consume in the same step with the backing papers. If the abrasives fly away at beginning, then the backing papers will burning the work-pieces' surface. Or if the abrasives can't fly away well together with the work-pieces' grits , then the flap discs remove-stock ability will decreased.

There 3 pcs flap discs in the photo and all is 125mm-60#. the left one is ours zirconia line after grinding stainless steel 304# 15 minutes, the middle one is the ceramic line after grinding same work-piece 20 minutes and the right one grinding for 30 minutes. we can see from the photo - the abrasives consume in the same step with the backing papers with long lifespan.

*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) Different flaps-combination achieve various using requirements. Normally combination are 
   
              >>>A + A<<<              >>>A+Z<<<               >>>Z + Z<<<

c) Best working angles

Grinding     (15~30')                          finishing workings     (0~15')

Blueshark Abrasives Flap Discs Overview



 BLUESHARK Abrasives Flap Discs are designed with abrasive cloth strips glued on to a rigid fiberglass backing in a fan arrangement. It's set grind and finish in one step, resulting in fewer time-waste and efficiency-increased. The unique construction allows for new grain to be constantly in contact with the surface with the flaps continually wear out. The life of a sanding flap disc can be 15~20 times that the fiber disc, resulting in a major cost reduction in both labor and material costs.

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


abrasives 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 ?


flap discs application 
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. 

t29 shape flap disc        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.  

t27 shape flap disc       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.
flap disc grit size recommend

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

flap disc testing
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. 

Now maybe you got a general idea how to choosing correct flap discs, if still any question or need more details, welcome Contact us  and we will try our best down your grinding cost!
