2023.07.03 A Comparison of Grinding Power — Abrasive Nylon Brushes Versus Ceramic Fiber Brushes

Many people think you need to chamfer edges when nylon and wire brushes cannot remove burrs sufficiently.
However, XEBEC provides an alternative solution– Ceramic fiber brushes.

XEBEC brushes can remove burrs left behind by nylon and wire brushes because they use ceramic fiber as the abrasive material.
They also contain a higher percentage of abrasive than nylon brushes.
This enables them to deburr harder materials such as stainless steel and titanium.
Graph1 illustrates the superior grinding power of XEBEC ceramic fiber brushes with respect to abrasive nylon brushes (60 times greater) and wire brushes (10 times greater).

The ceramic fiber brush used in the original test above was A32-CB40M, which is a hard brush with a 40mm diameter.
The abrasive nylon brush had a grit of 180.

Simple comparison of grinding power

This is a simple test to demonstrate once again the difference in grinding performance between ceramic fiber and abrasive nylon brushes.
You are welcome to try it yourself. The ceramic fiber brush used for the new test is A32-CB15M,
which is the same hardness as the original brush, but with a smaller (15mm) diameter.
The abrasive nylon brush used is a 13mm diameter cup-type.

The surface of the workpiece exhibits the characteristic cutter marks of a face milling tool.
Burrs are also evident on the various edges of the workpiece as shown in Image 2.

The results

The finish from machining with the abrasive nylon brush is shown in Image 3.
While difficult to see in this image, the minute burrs have been removed.
However, the large burrs on the right side of the image have not been removed.
The large burrs left by the face milling tool remain angled into the hole.
The flexible bristles of the nylon brush are not capable of removing these burrs.

The finish from machining with the XEBEC ceramic fiber brush is shown in Image 4.
The edge appears to be overly rounded.
However, this can be improved by reducing rotational speed and increasing feed rate.
Note that the cutter marks have been removed.

This test demonstrates the high grinding power of XEBEC’s ceramic fiber brushes.
In addition to deburring, XEBEC ceramic fiber brushes are frequently used to improve surface roughness,
remove cutter marks, and disguise marks from mismatched machining.

Please contact XEBEC Technology or your nearest distributor if you are interested in removing large burrs from machined edges.
We provide brushes on loan for testing.
