Engine Cylinder Hone Brush
This brush can be used to remove burrs from cross drilled holes leaving a clean, radiused intersection. Due to its unique shape, hone brush can be used online in machine tool applications or offline as a secondary operation. Engine cylinder hone brush is self-centering and self-aligning to the bore so elaborate, rigid set-ups are not required. It is commendable to use the tool in the main bore into which the cross holes break. Best results are obtained by rotating and stroking the brush a few strokes in a clockwise direction, removing the tool from the part, reversing the spindle and then rotating and stroking the tool in a counter clockwise direction for a few more strokes. Aforementioned forward and reverse rotation creates a more symmetrical deburring pattern.
Anhui Union Brush pioneered the concept of a finish and is a strong proponent of the benefits of a cross hatch. The concept involves using hone brush to remove the peaks produced by prior machining operations to create a substantially flat or plateau finish. A plateau finish created by the elimination of peaks allows rings and seals to seat without damaging their edges. The lubrication control and retention,reduce seepage in hydraulic and pneumatic applications and promote longer seal life all is credit to the cross hatch pattern.
