In the fields of machining and manufacturing, dealing with burrs is a common challenge. It is well known that burrs can negatively affect the assembly, use, and appearance of parts, and they may also pose serious threats to product performance and safety. Therefore, the deburring process is an essential step to ensure product quality. This article delves into the classification of burrs, removal methods, and the professional application of non-woven products in deburring.
Burrs are typically classified into three types based on their size: large burrs over 0.1mm, medium burrs between 0.1mm and 0.05mm, and micro burrs smaller than 0.05mm. Large burrs are visible to the naked eye, while medium and micro burrs can be detected by touch or using a cotton thread.
Large Burrs (>0.1mm): These burrs are easily visible.
Medium Burrs (0.1mm to 0.05mm): These are not easily visible but can be felt by touch.
Micro Burrs (<0.05mm): These can be detected by observing the fibers left on the part when wiped with a cotton thread.
The key to burr removal is to avoid altering the dimensional accuracy, shape, or positional accuracy of the workpiece. An inappropriate deburring method or product may create new burrs or even damage the workpiece.
There are various methods for deburring, including mechanical deburring, electrochemical deburring, thermal deburring, magnetic abrasive deburring, ultrasonic deburring, jet deburring, and laser deburring. Among these, the chosen method should provide stable processing quality, high production efficiency, convenience, and minimal damage to the workpiece. Compared to other methods, non-woven abrasive wheels stand out due to their efficiency, safety, and aesthetic appeal.
The elastic and self-sharpening nature of nylon abrasive wheels ensures no secondary burrs, maintaining the shape and size of the workpiece. Medium or small burrs can be effectively treated with Pengyu non-woven polishing wheels.
No Secondary Burrs: Unlike traditional tools such as grinding wheels and abrasive belts, non-woven polishing wheels do not create new burrs after deburring.
Maintaining Workpiece Shape: Non-woven polishing wheels can remove burrs while preserving the original shape and dimensions of the workpiece.
Flexibility and Elasticity: These wheels adapt to complex workpiece surfaces, including recessed areas.
Safety: Suitable for both oily and aqueous environments, with some resistance to acids and alkalis.
EXL and EXL Pro Convolute Wheels
Their flexibility helps remove surface imperfections while being wear-resistant, reducing the frequency of wheel replacement. These high-quality, high-performance products improve surface conditions efficiently without altering the workpiece shape, offering deburring speeds 30% to 50% faster than traditional products.
Light Deburring Convolute Wheels
Ideal for removing fine burrs and providing a high-polish finish. Their good conformity makes them suitable for light deburring, polishing, and fine finishing, maintaining critical tolerances while offering a refined polish.
Deburr & Finish Pro Unitized Wheels
Versatile for finishing, blending, and deburring, these products excel in automated robotic grinding applications due to their conformability and durability, allowing for efficient polishing and deburring without altering the workpiece surface.
The effectiveness of deburring depends on several factors that should be considered comprehensively:
Speed of Grinding Tools or Workpieces: Choose the appropriate speed based on the material, abrasive, and process requirements in consultation with an engineer.
Grit Size of Non-Woven Polishing Wheels: Select the grit size based on burr size and surface quality requirements. Too fine a grit may not remove burrs effectively, while too coarse a grit can damage the surface.
Based on current applications, deburring wheels are suitable for scenarios requiring high surface quality, high production rates, and automated control.
With continuous technological advancement, the application of non-woven deburring wheels in high-end parts manufacturing is becoming increasingly widespread. Choosing the right deburring product and method can enhance the appearance and performance of products while ensuring their safety and reliability.
