How to Choose the Right Type 27 Grinding Wheel For Your Job

Selecting the correct Type 27 wheel depends on your specific needs. Consider the following factors:

• Abrasive Material: Match the abrasive type (aluminum oxide, silicon carbide, zirconia alumina) to your material.
• Grit Size: Choose a grit size based on the desired finish—coarser grits for fast material removal and finer grits for smooth finishes.
• Bond Strength: Ensure the bond strength aligns with your application’s demand for durability and performance.

Grinding Wheel Maintenance and Usage Tips

To maximize the life and performance of your Type 27 grinding wheels, follow these tips:

1. Proper Storage. Store wheels in a dry environment to prevent damage from moisture.  Storing your grinding wheels in humid and moist environments can reduce the overall life of the product.
2. Correct Mounting. Ensure the wheel is properly mounted on the grinder to avoid imbalance and potential accidents. If the grinder starts violently shaking when you turn it on, TURN THE GRINDER OFF and inspect the mounting.
3. Appropriate PPE. Always wear appropriate personal protective equipment, including safety glasses, gloves, and hearing protection. Benchmark has a full range of PPE for proper grinding protection.
4. Regular Inspection. Frequently inspect wheels for cracks or wear and replace them as needed. Cracked wheel can break apart in chunks.
