Tech Tips

The Difference

What makes XEBEC® Ceramic Fiber so unique?

Each fine alumina fiber rod is made by binding together 100 alumina fiber filaments (ALF), each only serveral μm in diameter. The tips are the actual cutting edges so there is no damage to the perfipheral area of the part.

Self-sharpening tips lead to superior grainding performance. End-to-end solid abrasive rod material assures consistent performance.

Unlike brass wire, steel wire and abrasive impregnated nylon brush filaments, the unique design of the XEBEC fiber rod allows it to maintain its shape with no deformation even after repeated use. This leads to consistent performance time after time.

What is cutting fiber?

Cutting fiber is the world's only brush made by continuous ceramic fiber. This unique material allows for high performance grinding power, consistent performance and superior surface finish.

Red Cutting Fiber

Red Cutting Fiber

The red is more flexible and will conform to slight work piece variations. It is best used on burrs that are ≤ 0.1mm (.0039") in thickness or materials that are < 45 Rc.

White Cutting Fiber

White Cutting Fiber

The WHITE is more rigid and has more aggressive grinding action that will provide longer tool life, run at higher speeds and it is best suited for harder materials. Because of it’s rigidity, it is not best suited for interruptions and uneven surfaces.

Blue Cutting Fiber

Blue Cutting Fiber

The BLUE is the most aggressive cutting fiber, three to four times more aggressive than white. It handles burrs up to 0.5mm when the burr is vertical to the brush tip and 1mm when the burr is horizontal to the brush tip.

Brush Size Guide

How to choose the correct brush size?

Use a SMALLER brush: For the customer that prefers a less expensive tool that requires multiple passes.
Use a LARGER brush: For the customer that is most concerned about minimizing cycle time.

What are the key operating parameters for cutting fiber brushes?

RPM: Performs well between 60 - 80% of maximum RPM.
Depth of Cut: Keep 0.020 - 0.060 D.O.C. depending on the burr direction.
Feed Rate: Achieves optimal performance between 80 - 200 inches per minute. Higher feed rates are possible depending on the diameter of the brush and the material.

How to decide the direction of rotation?

Rotation direction should be up cutting. Grinding power is greater when the rotation direction of the front side of traveling is against the burr generation (climb milling).

Safety Warning

Cutting fiber brushes and stones are cutting tools and are often rotated at high speeds with a power tool or in a machine tool. They should never be operated at higher than the maximum speeds listed. When using these tools, safety glasses and gloves should be worn. Breathing the dust created by using these products for prolonged periods of time should be avoided.
