STA = steel wire ROF = stainless steel wire MES = brass wire PA = polyamide SIC = silicon carbide bristles Interior Brushes These brushes are varied for many different uses: not only for cleaning of tubes, gratings, sleeves and cylinders. Interior brushes regu- late current velocity in tubing systems. They are similar to the double spiral tube brush- es for deburring cross drillings etc. On these pages are shown standard brushes, single spi- ral having two drilling wires and the double spiral having four. Sleeve Brushes Sleeve brushes have a double spiral and are particularly stable types of tube brush- es whose trimming is cut to a conical point. Used in machines they are beneficial for cleaning the sleeves (internal threads) of con- tainers, e.g. after galvanisation. Mechanical Application Only use the brush with the indicated maxi- mal peripheral speed (RPM max.). The max. RPM only is allowed when the brush is clamped min. for 10 mm into the tool. When the brush is inserted into the suitable work piece, higher RPMs are possible. Only use the brush right rotating. Brushes with doublespiral Brushes with a double spiral are mainly used for the treatment of larger diameters or for the treatment of hard materials. A double spi- ral is more stable and has a higher resistance against untwisting. Hence the brushes can be exposed to higher loads.
