How to Choose the Right Mounted Wheel for Your Grinding Task

This article outlines the key factors to consider—such as abrasive type, grit size, bond material, and shape—to ensure optimal grinding performance across a range of applications.

Introduction

When it comes to precision grinding and deburring, the mounted wheel is one of the most versatile and essential tools in industrial machining. Whether you're polishing mold cavities, removing burrs from intricate parts, or refining detailed contours, choosing the right mounted wheel can significantly impact your efficiency and results.

As a leading manufacturer of abrasive solutions, Bay Union is dedicated to helping professionals select the ideal mounted wheel for their specific needs. This article outlines the key factors to consider—such as abrasive type, grit size, bond material, and shape—to ensure optimal grinding performance across a range of applications.

1. Choose the Right Abrasive Material

The abrasive material determines how effectively the mounted wheel can cut or grind specific workpieces:

• Aluminum Oxide (A/O): Great for general-purpose grinding on steel and ferrous metals.
• Silicon Carbide (SiC): Best for softer materials such as aluminum, brass, rubber, or stone.
• CBN (Cubic Boron Nitride): Designed for hardened steels and heat-treated alloys.
• Diamond: Ideal for non-metallic materials like glass, ceramics, and carbide.

2. Select the Proper Grit Size

Grit size affects both cutting performance and surface finish:

• Coarse Grit (46–60): Removes material quickly, suitable for rough grinding.
• Medium Grit (80–120): Ideal for general-purpose applications.
• Fine Grit (150+): Used for fine finishing or polishing tasks requiring smooth surfaces.

3. Common Bond Types

The bond holds the abrasive grains in place. Two of the most common bond types for mounted wheels are:

• Vitrified Bond: Known for strength, rigidity, and heat resistance—suitable for high-precision grinding.
• Resin Bond: More elastic and forgiving—ideal for smooth finishes and softer materials.

Choosing the right bond depends on the nature of your workpiece and grinding requirements.

4. Common Shapes and Uses

Mounted wheels come in various shapes to suit different grinding needs. Some of the most commonly used include:

• Straight (cylindrical): The most standard type, used for general grinding and internal surfaces.
• Conical: Great for reaching narrow spaces or angled surfaces.
• Ball/Bullet: Suitable for detailed deburring or curved internal shapes.
• Tapered or Oval: Used for heavier material removal or complex contours.

Selecting the appropriate shape ensures better access to the workpiece and improved grinding control.

5. Shank Size Compatibility

Make sure the mounted wheel's shank size matches your tool or machine collet. Common shank sizes include 3mm and 6mm. At Bay Union, we offer custom shank dimensions to suit a variety of machine types and applications.

6. Consider the Workpiece Material and Grinding Speed

Different materials and grinding speeds may require different types of mounted wheels. For harder metals or high-speed grinding, a vitrified bond and harder abrasive like CBN may be appropriate. For softer materials or slower speeds, a resin bond may be more effective.

Always follow recommended RPM ratings for safety and best results.

7. Partner with a Trusted Manufacturer
