FEATURES OF THE CERAMIC CROSS-HOLE BRUSHES
The "Ceramic Cross-Hole Brush" can be used to efficiently deburr bores.
The "Ceramic Cross-Hole Brush Extra Long" is particularly suitable for slotted holes.
A special feature that distinguishes the extra long fibre rods from the standard fibre rods is a guiding ring made of plastic, which is located underneath the brush head. This guiding ring stabilises the brush and prevents the tool from staggering.
CHARACTERISTICS OF AI2O3 HIGH-PERFORMANCE CERAMICS
- Consistent grinding performance thanks to self-sharpening, durable cutting edges
- Powerful grinding properties
- Excellent surface finish and deburring results
- Versatile use, e.g. on machining centers, special machines, drilling machines, robots, etc.
- The flexible fiber bristles gently adapt to the shape of the workpiece
- Long service life, resulting in higher productivity and lower costs
The bristles of the brushes are composed of approx. 1000 bonded fibers with a diameter of only a few µm, which consist almost entirely of abrasive ceramic. The tips of each fiber are the cutting edges, which are self-sharpening. This results in a uniform abrasive effect, which leads to constant and excellent polishing and sanding properties right to the end. In contrast to wire brushes, the ceramic fiber rods always return to their original shape after processing.

The centrifugal force generated by the rotation guides the flanks of the ceramic fibers to the cross holes and efficiently removes fine burrs up to 0.1 mm burr root thickness. These are ground off without damaging the bores. The Cross-Hole Brush can be used, e.g. on machining centers, special machines, drills, robots and much more. The "Standard" ceramic cross-hole brush is intended for bores from Ø 3.5 mm up to a maximum of 20 mm.
For larger diameters, the previously used blue ceramic fiber A33 was optimized and the cross-section of the fibers was adjusted so that they are more flexible but at the same time more stable and can therefore cling better to the bore wall with large bore diameters from 20 mm to a maximum of 35 mm. The new ceramic fiber A34 is used in the newly developed "Ceramic Cross-Hole Brush Extra Large".
Please note: For the time being, please only inquire about the new "Ceramic Cross-Hole Brush Extra Large" by telephone or e-mail.
The functional principle of the "Cross-Hole Brush Extra Long" is the same as that of the standard Cross-Hole Brushes, but the "Cross-Hole Brush Extra Long" is designed for large bore depths from 140 mm up to a maximum of 370 mm.
As the guiding ring has to be adapted exactly to the main bore diameter, the entire tool consists of three separate parts (brush head, guiding ring and shaft), which have to be ordered separately. Therefore, please be sure to specify the main bore diameter of the workpiece to be machined when ordering.
The brushes are suitable for dry as well as for wet processing. The brush head is replaceable and can easily be unscrewed. The shaft is reusable.

PUSH OR PULL? The feed direction decides.
Sometimes we are asked why, under certain conditions, the cross-hole brush should be pulled back first during processing and not pushed forward first...
The tips of every ceramic fiber are the cutting edges. These must be correctly aligned in order to remove the desired burrs at the root of the burr. It is therefore crucial that the feed direction (i.e. forwards or backwards) is correct.

1. INSERTION MOVEMENT Insert the tool into the bore while the spindle is stopped. |
 |
Start the spindle clockwise in the bore just before the cross-hole to be deburred. |
 |
3. FOR- & BACKWARDS MOVEMENT Guide the fiber rods in front of and behind the cross holes. In the backward movement, we recommend additionally changing the spindle direction. |
 |
4. WITHDRAWAL FROM THE BOREHOLE Before the tool exits the bore, the spindle rotation must be stopped. |
