103 102 Mi c ro I nter i or Brushes INTERIOR BRUSHES Interior brushes with zinc coated twisted wire and single spiral Due to the filling of aluminium oxide or sili- con carbide their usage is more flexible than with conventional interior brushes. Interior brushes with abrasive filaments are usually used for deburring bores, cross bores, o-ring recesses and for polishing and cleaning small bores. Due to the flexible surface of the bristles the interior brushes suit to the contour of the bore and areas which are hard to reach can be treated. Abrasive bristles also have grin- ding effects on the side. That allows a round- ing of the edges also on cross bores. Also brushes with diamond filling are avail- able, that causes an even more aggressive surface of the brush. Micro Interior Brushes, Steel Wire Micro interior brushes with steel wire are used as thread brushes for descaling, debur- ring or cleaning: • Cross corners • Crossovers • Tap holes • Slots The brushes can be used either manually or mechanically. Please do not hesitate to contact us, we will also find for special applications a compati- ble solution. Due to a fully automated production, LESSMANN offers high quality to reasonable prices. 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.
