Turning Brush for lathes
For deburring cross-holes and grooves as well as for external and internal threads on the lathe with stationary tool

FEATURES OF THE CERAMIC TURNING BRUSH
- Automated and effective deburring of small burrs < 0.1 mm on lathes
• Use as a static tool in the lathe turret
• Deburring directly on the machine
• No manual deburring effort, no retooling
• Consistent deburring quality and high process reliability - Deburring of several cross holes in a single step
- Deburring of external threads thanks to the adjustable brush angle in the tool holder (for square shank tool holders)
- Also suitable for polishing lateral surfaces, faced surfaces as well as bores
- The cutting effect can be maximized by the ceramic fibers approaching the burrs at an optimal angle; stiff fibers (steep angle) and slow feed increase the effectiveness/aggressiveness
- No complicated programming required, as in most cases the tool is moving from Z to Z+ only

The CERAMIC FIBER TURNING BRUSH is available in four versions. Two types with square shank and adjustable brush angle and two types with round shank and fixed brush angle.
SQUARE SHANK TOOL HOLDER WITH ADJUSTABLE BRUSH ANGLEThe brush angle can be adjusted on the square shank tool holders to optimize the deburring effect, while the brush angle of the two round shank tool holders is fixed at a flat angle. Flat angles are suitable to de- burr irregular surfaces such as cross holes.
The square shank tool holder allows steep brush angles (almost vertical as well). This concentrates the grinding power of the ceramic fibers in the tip of the brush, making it ideal for deburring threads.
FOR EXTERNAL THREADS: THE STEEPER, THE BETTER
A steep brush angle (less than 90°) enables defined contact between the ceramic fibers and the Burrs without splitting the brush bundle, ensuring high grinding performance. When moving the brush over the thread, it strokes over the thread tips, removing any protruding burrs.

The ceramic fiber brush must always be moved in the opposite direction to the brush tip. This pulling motion minimizes bristle deflection. A pushing motion would cause the bristles to spread and break.
DEBURRING CROSS HOLES
Flat brush angles and large feed rates are required to deburr cross holes. For a more uniform result, deburring can be performed in clockwise and counter clockwise rotation.
THREAD DEBURRING
A steep brush angle (22.5°) is required for deburring external threads. The correct direction of rotation of the workpiece is clockwise M03 for right-hand threads and counterclockwise M04 for left-hand threads.
