XEBEC Brush™ Surface FAQ

XEBEC Brush™ Surface

Does it contain abrasive grains?

No, it does not. The ceramic fibers work as abrasive materials.

How do you use it?

For the cup type, attach the shank of the sleeve to an automatic tool changer (ATC) on a machining center or other equipments. Then rotate the tool and remove burrs after cutting work on machine. It can also be used with robots, special machines and drilling machines.
For the end type, attach the tool to an electric tool (or machine tool). It can not be used with a pneumatic tool.

What size of burrs can be removed?

The tool aims to remove burrs with the size that can be bent by pushing one’s fingernail against it.

How should I set up the machining conditions?

Refer to the table that shows the recommended initial conditions, such as rotation speed, depth of cut and feed rate.

Is it possible to chamfer or make a corner R portion?

The cup type brush can be used for chamfering or rounding an edge.

Can it be used for wet machining?

The tool can be used for both dry and wet (both oil-based and water-soluble) machining.
Wet machining may improve surface finish quality and tool life.

Are there any negative effects on the surface from using the brush?

The brush is capable of surface finishing, and it can improve surface roughness to around Ra=0.1μm.
XEBEC Brush is developed by applying the technology for XEBEC ceramic stone which is used for mold polishing.
XEBEC Brush does not contain any abrasive grains,thus the brush does not leave any scratches on the surface.
However,depending on the pattern of the brush, there are cases where the appearance looks a little cloudy on aluminum surface which was finished with a diamond cutter.

What is the finishing quality of the brush in terms of grit?

XEBEC brush does not define the grits. It is capable of finishing the surface up to around Ra=0.1μm.

How long is the tool life?

Tool life significantly varies depending on machining conditions, burr condition (size and direction) and workpiece material.
In one case study, where the tool was used for deburring after milling of an oil pan with 1m circumference (material:aluminum), a single brush lasted for 10,000 workpieces (straight line distance of 10,000m=10km)
Workpiece: Oil pan (automotive engine part)
Material: aluminum
Cutting process: 1m / piece
Result: 10,000 workpieces / brush (total length 10km)

Can the tool be used manually?

The end type brush can be used for hand work. However, the cup type brush can not be used manually because it judders violently. Furthermore, the appropriate depth of cut cannot be kept when using the cup type manually, so deburring and polishing cannot be done suitably.

How should I clean the brush?

Remove the attached dust or coolant by blowing air, etc.

What are the truing and dressing methods?

You can form a brush using a diamond disc blade.
For more information, see the maintenance page.

Is it possible to regrind (truing) or re-embed the brush?

You can regrind the brush by forming it using a diamond disc blade. We do not offer regrinding or re-embedding services. For more information, see the maintenance page.

Is it possible to purchase just the sleeve-fastening screw?

Yes, it is possible. XEBEC's genuine parts are recommended. Contact us for the details.

The tip of the sleeve is thinning. Why?

The inner part of the tip of the sleeve is worn out and become thinner as it is gradually ground by the sides of the brush over a long period of use. Replace the sleeve.
It is possible to purchase the outer cylinder of the sleeve alone. Contact us for the details.

Can you produce a tool with shorter tool length?

It is possible to produce a brush that is shorter than the standard specification. However, it is not possible to provide shorter metal parts (i.e. sleeve, shank).

Do you handle special order products?

Yes, we provide services such as extension of bristle length and modification of the brush tip shape. Please contact us for more information.
