Instruction manual download

Usage instructions

Brush insertion direction

Brush must be inserted from a main bore.
Burrs cannot be removed in case the brush is inserted from a secondary hole.

Precautions for use

The Brush will break off if:
○ machined beyond the maximum rotational speed
○ used with a pneumatic tool
○ rotated outside the cylinder (outside workpiece)
○ the distance from the hole entrance to the target is 20 mm or less

The clamp length must be 30mm or more when attaching this tool on the machine,
and make sure it is affixed rigidly.

In the following cases when used under the initial processing conditions, the Brush may break off,
○ Off-center cross hole, angled cross hole and long hole
○ The cross-hole diameter larger than φ12
When using this product on a cross-hole diameter larger than φ12, please contact us.

In the following cases, brush damage may occur.

How to select Brush size

Select Brush size based on main hole diameter (brush insertion hole).

For a bore depth over 140mm, Extra-Long type is available as a customized item.

For use

1. Insert the brush while not in motion.
*If you rotate the brush outside the cylinder, the bristles may be damaged or scattered and may cause injury to the operator.

2. Rotate the tool past the cross-hole
*Consistent edge quality can be obtained by rotating the tool in both CW and CCW direction.

3. Process while pulling the brush back.
*Pulling the brush back past the cross holes prevents burrs from being laid flat against the interior surface of the cylinder.

4. Process while pushing the brush forward.
*Pushing the brush forward ensures that burrs remaining upward are removed.

5. Stop the brush rotation.

6. Remove the brush while it is at rest.

Machining parameters

Recommended rotational speed and maximum rotational speed

A34 (Blue)
Product code Recommended rotational speed Maximum
rotational speed
CH-A34-15 7000min⁻¹
9000min⁻¹
CH-A34-20
CH-A34-25

Feed rate and rotational direction

Feed rate: 300mm/min.

 

Rotational direction: A uniform deburring and edge quality can be achieved by rotating the tool in both clockwise and counter-clockwise directions.

Recommended rotational speed

Recommended rotational speed is different depending on the brush diameter.
See the recommended rotational speed and the target hole diameter shown below. 

The continuous line (-) represents the recommended rotational speed.
The dotted line (- – -) represents the rotational speed when the brush is worn down 10mm.
You can continue to use the tool by adjusting (i.e. increasing) the rotational speed according to the wear amount.
