How to choose suitable polishing and abrasive materials?

Choosing the right polishing and abrasive materials is incredibly important to get the best project-finishing results. Below are some useful tips to help select the right materials that will meet your specific requirements.

Tips for Choosing Abrasive Materials:

1. Choosing the Right Material for Aluminum Alloy Hardware Components:

After stamping, stainless steel parts require the removal of burrs and sharp edges. Opting for abrasive materials made from white corundum yields better results than using resin-based plastic abrasives. For die-cast zinc alloy or aluminum alloy hardware components, resin-based plastic abrasive materials are more suitable. Using brown corundum abrasive materials may risk causing surface imperfections.

2. Selecting Polishing and Abrasive Materials for Various Materials:

For materials like iron, stainless steel, cast iron, powder metallurgy (magnetic) cores, aluminum alloys, zinc alloys, copper, and plastics, high-alumina ceramic abrasive materials with capabilities for surface polishing, coarse grinding, precision grinding, gloss polishing, pre-plating fine grinding, and outstanding vibration performance are recommended.

3. The Vital Role of Abrasives in the Polishing Process:

To address rusting issues in various hardware components, it's essential to choose abrasives that have anti-corrosion properties. These abrasives not only polish but also serve functions such as oil and dirt removal, cleaning, rust prevention, lubrication, buffering, and reducing abrasive wear, making them indispensable tools for achieving optimal finishes.

4. Understanding the Role of Brighteners:

Each type of material requires a specific level of brightness. Brighteners play a crucial role in achieving the desired level of glossiness during the polishing process. They serve as chemical agents for surface polishing in various grinding and polishing machines.

Commonly Used Abrasive Materials in Grinding Tools:

The most frequently used abrasive materials in grinding tools include brown corundum, white corundum, black silicon carbide, and green silicon carbide.

1. Brown Corundum:

- High toughness, suitable for grinding materials with high tensile strength like carbon steel, alloy steel, malleable cast iron, and hard bronze.

2. White Corundum:

- Higher hardness than brown corundum, with excellent cutting performance. Ideal for precision grinding processes of hardened steel, high-carbon steel, high-speed steel, and similar materials.

3. Black Silicon Carbide:

- High hardness, brittle and sharp. Recommended for grinding and cutting materials with low tensile strength, such as cast iron, glass, ceramics, stones, and refractories.

4. Green Silicon Carbide:

- Higher purity than black silicon carbide. Suitable for grinding hard and brittle materials like hard alloys, optical glass, gemstones, and agate.

Tools for Abrasive Materials:

Abrasive tools, also known as abrasives, are essential for shaping workpieces during the grinding process. They serve as carriers for abrasive agents. These tools should have lower hardness compared to the workpiece, along with a certain degree of wear resistance. They are commonly made of gray cast iron. The choice of abrasive tools depends on factors like workpiece material, size, and complexity.
