How to select Brush color

Grinding power differs depending on Brush color.
Refer to the chart below and select the brush color based on the workpiece material and burr root thickness

Deburring

Cutter mark removal and polishing

Brush size

Select the brush size based on workpiece size and shape, interfering objects such as jigs, attachable tool length and cycle time. It is recommended to use the brush size which is 1.5 to 2 times wider than the width of the surface of the workpiece.

Please watch the video below to see what is the difference of processing paths by brush size.

Processing conditions

Set the processing conditions depending on the purposes, deburring or cutter mark removal and polishing.
The 3 parameters of basic processing conditions are shown below.
1. Rotational speed  2. Depth of cut  3. Feed rate

Other parameters are brush projection amount (the length of the brush projected from the sleeve) and direction of brush rotation, which is important in deburring process.

How to set processing conditions for deburring

Rotational direction

Rotational direction of the Brush has a significant impact on the deburring capability.

For burrs in horizontal direction (i.e. side burr) generated after milling, machining must be done by up cut whereby the brush pushes upward against the burrs from the bottom.
When down cutting, there is a possibility that the burrs may not be removed properly because the burrs may get bent and stuck to the surface.

For vertical burrs (i.e. top burrs), there is no significant difference by rotational direction.

Dry or wet machining

The tool can be used for both dry and wet (oil-based and water-soluble) machining.
Therefore, you can use the coolant which you are using in machining process.
Generally, wet machining are more effective to improve the surface finish quality and tool life.

How to adjust

If burrs remain

1. Increase rotational speed
Increase the rotational speed to the maximum.
If burrs still remain, then decrease the feed rate.
 
2. Check the rotation direction of the Brush

For horizontal burrs, up cut is recommended so that the brush tip pushes up the burrs.

3. Change the Brush color
Change the Brush with higher grinding power.
The grinding power of the Brush : Blue > White > Red > Pink
Make sure to select Brush color based on the workpiece material and burr root thickness.

If the edge is too rounded

1. Increase feed rate

To make sharp edge, increase the feed rate in 1,000mm/min increments within the range where burrs can be removed.
Increasing the feed rate also helps to reduce the cycle time.

2. Decrease rotational speed

Decrease the rotational speed in 10 to 20% increments within the range where burrs can be removed.

3. Check the Brush color

The grinding power of the Brush : Blue > White > Red > Pink
Select Brush color based on the workpiece material and burr root thickness.

To extend tool life

1. Increase feed rate

Increase the feed rate in 1,000 mm/min increments within the range where burrs can be removed.

2. Decrease rotational speed

Decrease the rotational speed in 10 to 20% increments within the range where burrs can be removed.

If the surface becomes rough

Check the Brush color

Change the Brush with higher edge quality.
Edge quality of the Brush: Pink > Red > White > Blue
Make sure to select appropriate Brush color based on the workpiece material and burr root thickness.

To improve surface roughness

1. Check the Brush color

Make sure to select appropriate Brush color.
Edge quality of the Brush : Pink > Red > White > Blue

 
 
2. Wet machining

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

3. Increase the number of passes

When comparing in the same cycle time, increasing the number of passes makes bigger difference than decreasing feed rate.

Maintenance

Truing

When the brush is worn out unevenly, you can form the tip of the brush using a diamond disc blade.

Truing by a drilling machine

Truing by a lathe

If you want to cut off the brush, cut from the side of the brush using a diamond disc blade.

Operation safety measures

Use of protective equipment

Always wear protective goggles, gloves and masks when operating the tool.
Wear long sleeved clothing and close the cuffs and outerwear sleeves to minimize skin exposure.

Be careful of cutting particles

Cutting particles and burrs may scatter within an area around the work as the brush rotates.
Stay clear of this area.

Caution for your surroundings
The area around your work is hazardous in case flying pieces of fiber rods from the tools and grinding powder may scatter, enclose your working area to prevent other people from entering, or have the people surrounding your working area wear protective equipment as well.
Warning

Follow the precaution in use and safety measures for operators above without fail.
If you fail to observe them, there are following risks.

*A tool or a part of tool may crack, drop off, distort or break.
*Broken pieces of a tool or grinding dust may stick into your skin, or at worst stick into yours eyes, causing blindness.
*Dust generated by machining process may bring up skin irritancy or allergy.
