Hoffmann Group presents its Garant disc brushes for precise deburring, edge filleting and surface finishing of milled, flat precision parts. The brushes are suitable for direct application in a CNC machine or a robot cell, and applied immediately after the machining process they reliably remove unwanted burrs and fine milling marks. The tools are also suitable for precisely brushing down workpieces that have been produced using a sintering, punching, die casting or pressing process, and for creating smooth surfaces.
The Garant disc brushes make easy even finishing valve plates with internal labyrinths, and thanks to their maximum-density yet flexible bristles they are able to deburr complex components without manipulating their shape. The nylon bristles are firmly cast in place and impregnated with abrasive grit, and won’t break off even at high speeds, producing a strong, consistent brushing effect due to the high proportion of abrasive grit they contain. That means burr-free, smoothly ground surfaces plus an exceptionally long service life and controllable wear behavior.
The disc brushes are particularly well suited to wet machining and are compatible with all measuring head and combination face mill adapters. Hoffmann Group can also provide customers with disc brushes adapted specifically to suit their needs. The existing range of Garant disc brushes will soon be expanded to include circular brushes for deburring work on outer surfaces.
