Features
・ Suitable for use on machining centers, robots, custom machines,
and drilling machines – easy to automate.
・ Superior grinding performance thanks to the self-sharpening action of the cutting edge of
the Fine Alumina Fiber rod tips. The continuous cutting edge provides stable grinding performance.
・ Consistently superior grinding performance can be achieved by establishing suitable processing conditions.
(cutting depth and rpm)
・ Can deburr and finish edges simultaneously.
・ Can improve surface roughness in a shorter time, thus shortening the finishing process.
・ Ideal for fine deburring and surface finishing of automotive parts, aircraft parts, and machine parts.

 

■Fiber Rod Type
Fiber rod Features
A11
(Red)		 Easy to fit, more suitable for fine deburring than A21(white).
Thanks to the softness of the fiber rod, it will fit with uneven workpieces.
Burrs are removed without breaking the edge pattern.
Suitable for grinding and surface finishing of iron. Especially superior grinding performance in wet processing
Wet processing can improve surface roughness in a shorter time.
A21
(White)		 Superior grinding performance thanks to the high rigidity (compared with A11).
Can remove rather large burrs after machine processing.
Wet processing can improve surface roughness in a shorter time.
 
 
Structure
■Comparison of structure and features with abrasives-impregnated nylon brushes

Structure
Consistent rigidity A single Fine Alumina Fiber Rod is made by binding together 1,000 Alumina Fiber Filaments(diameter ø10μm for red rods and ø15μm for white rods).

Therefore, this structure maintains a consistent rigidity and there is virtually no fiber rod configurational change during the deburring process.		 The abrasive grain is impregnated in nylon.
The nylon base gives it flexibility but low rigidity.

So there is rod configurational change in the deburring process.
Superior grinding performance ALF makes up approximately 75% of the total weight;

The self-sharpening action of the cutting edge on the Alumina Fiber Rod tips and continuous cutting edges provides superior grinding performance.		 Abrasive grain makes up only 30% weight; its self-sharpening action is weaker, resulting in lower grinding efficiency.
Uniform fine finishing Thanks to the multitude of uniform Alumina Fiber on the rod tips, stable and uniform finishing can be achieved; keeping superior grinding performance. Due to the variation in abrasive grains diameters, it’s hard to get uniform finishes
No clogging Thanks to the self –sharpening action of the cutting edge on the Alumina Fiber od tips, it’s difficulte to clog the tool. Due to less self- sharpening action, it’s easy to clog the tool.
For both dry and wet processing Thanks to the high thermal resistance (approx. 150℃), the grinding performance is stable even in dry processing.

Thanks to superior water-resistance, there is no decrease in rigidity even wet processing, providing stable grinding performance.		 Due to the low thermal resistance (approx. 90℃), the heat generated in dry processing results in decreased rigidity and molten nylon on the workpiece.

Due to low water-resistance, rigidity and grinding performance is decreases.
 
 
Usage, Applications
■Usage
  • Deburring of fine burrs (where the base thickness is 0.1mm or less after machine processing)
    and finishing of edges
  • Fine deburring of surfaces
    (1) Deburring and finishing of edges (pipe, connections, shafts etc.)
    (2) Deburring after small diameter bore (press, drill, laser) processing
  • Precision parts such as automotive engine parts that must be deburred while maintaining edge quality without secondary burrs
  • Grinding, and finishing flat surfaces, Gently uneven surfaces and free surfaces
  • The Hand Grinder Type is recommended for use with machining centers for free surface finishing

Use



■Attachiment Method

■Usage
[How to apply tool]
Apply from the direction of the occurrence of the burrs for effective deburring.

[Example 1]
This is an example of deburring and edge finishing of the inner and outer circumferences of a ring-shaped workpiece.

[Example 2]
Processing can be made more effective by setting the direction of rotation.
When burrs are larger or uneven in size, use of a wire brush for the first pass and the Cutting Fiber for second pass can make processing more stable.

[Example 3]
This is an example of using the cutting fiber through automated deburring
after cutting.
