Felt Wheel

The felt wheel is one of the most commonly used abrasive materials, widely applied in surface finishing and polishing processes for metal products such as stainless steel, copper, aluminum, and other alloys.
This product is especially useful in areas where large polishing machines cannot reach, providing high efficiency and an excellent surface finish.

Structure of the Felt Wheel

A polishing felt wheel is composed of three main components:
Felt fibers: The primary base material that provides structure and durability to the product.

• Felt fibers: The primary base material that provides structure and durability to the product.
• Abrasive grains: Typically made from aluminum oxide (Al₂O₃) or silicon oxide (SiO₂), offering effective grinding and polishing performance.
  
• Bonding adhesive: Evenly applied in layers to hold all components firmly together.

All these elements are compressed in a mold under heat and pressure, forming a solid and durable structure.
Notably, the open structure of the felt wheel provides excellent heat resistance, preventing burning or surface deformation when operating at high temperatures.

SPEC

Felt wheels are designed with various specifications to meet different polishing and surface finishing requirements:

• Diameter: 75 mm, 100 mm, 125 mm, 150 mm, 175 mm, etc.
• Thickness: 10–12 mm
• Bore diameter: 16 mm
• Hardness: From 7D to 12D, suitable for both light and heavy polishing tasks.
• Color options: Gray, red, white, black, blue
  

Backing material: Available in plastic or metal, providing enhanced durability and stability during operation.

Types of Felt Wheels

Currently, felt wheels are categorized into several types based on their intended use, material composition, and polishing level. Some common types include:

• Soft felt wheel: Used for gentle polishing to achieve a smooth and refined surface finish.
• Hard felt wheel: Suitable for tasks requiring higher abrasion, such as removing rust or surface stains.
• Adhesive coated felt wheel: Designed to enhance adhesion strength and extend product lifespan.

Applications of Felt Wheels

Polishing felt wheels are essential tools in many industries thanks to their flexibility and outstanding performance:

Surface treatment

• Remove scratches, weld marks, and rust stains on metal surfaces.
• Clean and prepare surfaces to improve coating adhesion, enhancing the overall finish of products.

Metal polishing

• Highly effective for materials such as stainless steel, aluminum, copper, and other alloys.
• Produce a bright, reflective finish, improving both the appearance and value of the product.

Industrial applications

• Remove oxide layers on metal surfaces, improving the conductivity of copper electrodes.
• Commonly used in mechanical processing, mold manufacturing, and household appliance production.

Media polishing

• In addition to metals, felt wheels are also used for polishing natural stone surfaces, creating a perfect glossy finish.

Advantages of Felt Wheels

• No speed limitation: Felt wheels can operate at various machine speeds, making them compatible with a wide range of grinding and polishing equipment.
• Easy to use: Compact and easy to handle, allowing access to narrow or hard-to-reach areas.
• High durability: Withstand high temperatures without deformation, even during continuous use.

Felt wheels are essential tools that play a significant role in surface finishing and polishing for both metal and non-metal materials.
With diverse designs, solid construction, and versatile applications, felt wheels are increasingly favored across many industrial and craft sectors.
Choosing the right type of felt wheel helps save time, enhance product quality, and achieve optimal work efficiency.
