No matching material found Try another material, grade, DIN number, grit or ISO group.

Maximum spindle speed: 12,000 RPM. The values above are recommended starting parameters and should be optimized on the actual component.

✓

Correct – Light Tip Contact

Use light axial contact for localized deburring, edge finishing and polishing.

✓

Correct – Controlled Angled Contact

For the 45° End Type, keep engagement light and use the formed tip to reach chamfers, corners and recesses.

Avoid – Excessive Side Loading

Do not force the ceramic fibers strongly sideways against an edge. Excessive bending can reduce stability and accelerate wear.

Recommended application: Fine machining burrs, localized edge finishing, cutter-mark reduction and polishing. Large or heavy burrs may require pre-machining before UFIBER finishing.

Problem	Recommended Adjustment
Burr remains	Use a coarser grit → slightly increase engagement → reduce feed → add another controlled pass.
Excessive edge rounding	Increase feed → reduce brush engagement → select a finer grit → reduce RPM if necessary.
Brush marks	Use a finer grit → reduce engagement → maintain stable movement → add a light finishing pass.
Excessive brush wear	Reduce engagement → check alignment → minimize side loading → verify runout and clamping.
Poor surface finish	Use a progressive grit sequence → reduce final engagement → maintain stable feed → check brush cleanliness.
Vibration / unstable contact	Stop operation → check chuck, runout, brush condition and workholding before restarting.

How to Use the UFIBER® End Brush

①

1. Select the Contact Geometry

Use the Flat End Brush for axial surface contact and the 45° End Brush for chamfers, corners or recessed features.

②

2. Start with Light Engagement

Begin with minimum brush engagement. Increase contact only when additional cutting action is required.

③

3. Maintain Controlled Movement

Move continuously over the machining area and avoid holding the rotating brush at one point for an extended period.

Brush Engagement: The engagement value represents approximate axial or radial deflection of the ceramic fibers against the workpiece and not the amount of workpiece material removed.

No matching material found Try another material, grade, DIN number, grit or ISO group.

Maximum spindle speed: 12,000 RPM. The values above are recommended starting parameters and should be optimized on the actual component.

Coolant Selection: Use the coolant method shown in the machining table as the starting recommendation. Coolant can assist with heat control, chip evacuation and surface-finish consistency. Always confirm compatibility with the workpiece material and production process.

Recommended RPM vs. Maximum RPM: The machining table provides recommended starting RPM ranges by material. 12,000 RPM is the absolute maximum spindle speed and should not be interpreted as the recommended speed for every application.

▥

Controlling Deburring & Polishing Performance

▲

Increase Deburring Action

Coarser grit → More engagement → Lower feed → Additional controlled pass

▼

Reduce Aggressiveness

Finer grit → Lighter engagement → Higher feed → Fewer passes

✦

Improve Surface Finish

Finer grit sequence → Light contact → Stable feed → Finishing passes

◷

Improve Brush Life

Reduce pressure → Correct alignment → Avoid side load → Minimum required engagement

Important: Do not compensate for insufficient cutting action only by increasing brush pressure. Excessive fiber deflection can reduce process stability and brush life.

⚒

End Brush Installation & Usage

①

01. Shank Grip

Grip the brush shank by at least 20 mm to ensure secure clamping.

②

02. Chuck Matching

Use a chuck or collet that correctly matches the brush shank diameter.

③

03. Minimize Runout

Keep spindle and tool runout as low as practical for stable brush contact.

④

04. Initial Engagement

Start with minimum contact and increase engagement gradually only when required.

⑤

05. Secure Workholding

Ensure the brush and workpiece are securely clamped before CNC operation.

⑥

06. Validate the Process

Confirm the parameters on the actual component before production use.

Manual & CNC Operating Speed Guidelines

✋

HAND-HELD

Manual Operation

1,000 → 3,000 RPM

Start at approximately 1,000 RPM. Once stable control is established, increase gradually up to 3,000 RPM.

▣

CNC / ROBOTIC

Automated Operation

Up to 12,000 RPM

Follow the RPM values specified in the machining recommendation table. Never exceed 12,000 RPM.

✓

Correct Brush Contact

✓

Correct – Light Tip Contact

Use light axial contact for localized deburring, edge finishing and polishing.

✓

Correct – Controlled Angled Contact

For the 45° End Type, keep engagement light and use the formed tip to reach chamfers, corners and recesses.

Avoid – Excessive Side Loading

Do not force the ceramic fibers strongly sideways against an edge. Excessive bending can reduce stability and accelerate wear.

Recommended application: Fine machining burrs, localized edge finishing, cutter-mark reduction and polishing. Large or heavy burrs may require pre-machining before UFIBER finishing.

End Brush Troubleshooting

Problem	Recommended Adjustment
Burr remains	Use a coarser grit → slightly increase engagement → reduce feed → add another controlled pass.
Excessive edge rounding	Increase feed → reduce brush engagement → select a finer grit → reduce RPM if necessary.
Brush marks	Use a finer grit → reduce engagement → maintain stable movement → add a light finishing pass.
Excessive brush wear	Reduce engagement → check alignment → minimize side loading → verify runout and clamping.
Poor surface finish	Use a progressive grit sequence → reduce final engagement → maintain stable feed → check brush cleanliness.
Vibration / unstable contact	Stop operation → check chuck, runout, brush condition and workholding before restarting.

◷

Brush Wear & Maintenance

↘

WEAR

Brush Wear Changes Cutting Behavior

As the ceramic fibers wear and become shorter, stiffness and contact behavior may change. Re-check the process when the brush has visibly shortened.

↔

PROCESS CONTROL

Compensate Gradually

If the process becomes too aggressive, reduce engagement, increase feed, reduce RPM if required, or select a finer grit.

✦

CLEANING

Keep the Brush Clean

Remove accumulated machining debris, dust and coolant residue. Contamination can reduce cutting consistency and surface-finish quality.

✓

INSPECTION

Inspect Before Production

Check the brush tip, shank, clamping condition and runout before use. Replace a damaged or unstable brush before production machining.

Process stability: Do not maintain performance by increasing pressure alone as the brush wears. Optimize engagement, feed, RPM and grit together.

⚠

End Brush Safety Precautions & Instructions

⚠

Operation Safety

• Do not exceed the specified maximum spindle speed.
• Do not use pneumatic-powered hand tools.
• Stop immediately if abnormal vibration occurs.
• Avoid prolonged machining at one fixed point.
• Ensure secure tool and workpiece clamping.

✓

Operator & Work Area Safety

• Wear suitable eye protection.
• Use respiratory protection where required.
• Use suitable dust and particle extraction.
• Keep flammable materials away from the machining area.
• Do not touch hot surfaces immediately after machining.

Process validation required: Machining performance depends on workpiece material, hardness, burr geometry, brush configuration, grit, machine rigidity, workholding and operating conditions.
