Stronger brush Frankfurt (I)

For the abrasive brush we should talk about three density ,its the filaments on the abrasive brush (craft density) the silicon carbide grit in the filaments and nylon density as the silicon carbide (material density).the first and the second density should have the logical ,and not much higher is much better ;and nylon density should have the basic of top quality ,lower the density -reducing the unit weight of the filaments, reducing the cost of material.

Why adopt low density filaments?

Adding water during the grinding . Prevented the high temperature making the filaments changing shape during the filaments friction in high speed .As the sequence of  the number of abrasive brush from thick to thin ,the pressure working on the grind should from big to small. Its logical for the skip .
Reducing the middle step excessively will affect the effect of grinding ,other size it will add the cost .Using the steel brush as possible. The abrasive brush as the first step could reduce the loss for the rough surface to abrasive filaments, extended the life of the abrasive brush.

How to use the abrasive brush rightly?

Usually ,steel and grit 36# abrasive brush is removing the surface loose and pan stereotypia; grit 46# 60# 80# for grind simply ;120# 180# 240# could polish simply ;320# 500# could polish fine ,to getting the archaized effect. If it is the first time to use the abrasive brush ,should test in each grit ,to choose from it  according to the kinds of stone and need .

How to choose varied kinds of brush?

According to the kinds ,it has Frankfurt (horseshoe),Diam 110mm round brush .Fickert (brad) and so on ;According to the grits included steel. 36# .46#60#80#120#180#240#320#500# and so on .Frankfurt is used in hand grinding machine ,industrial polishing lines step retreading machine ,round brush is used in hand grinding machine step retreading machine ;Fickert is used in automatic grinding machine .
