3. Setup
Before using the Tormek DE-250 Diamond Wheel, ensure your Tormek T7 or T8 wet grinding machine is properly set up according to its own user manual. The diamond wheel is designed for easy installation onto the machine's shaft. Always ensure the wheel is securely fastened and rotates freely before operation. For optimal performance and to prevent corrosion, mix the included 150 ml anti-rust concentrate with water in the water trough as per the instructions provided with your Tormek machine.
4. Operating Instructions
The DE-250 Diamond Wheel with its 1200 grit is ideal for achieving an extra fine finish on carving tools, knives, and other precision cutting instruments. Due to its fine grit, it is best used for honing and refining an already established edge, rather than for significant material removal or initial shaping. Always use the appropriate Tormek jigs and supports for your tools to maintain consistent angles and ensure safe operation. Apply light, even pressure against the rotating wheel, allowing the diamond surface to do the work. Regularly check the edge for sharpness and burr formation.
5. Maintenance
To maintain the performance and longevity of your Tormek DE-250 Diamond Wheel, it is crucial to follow these maintenance guidelines:
- Anti-Rust Concentrate: Always use the provided anti-rust concentrate in the water trough. This prevents corrosion on both the diamond wheel and your tools.
- Cleaning: After each use, clean the diamond wheel and the water trough to remove any metal particles or debris. This prevents clogging of the diamond surface and ensures consistent sharpening.
- Storage: Store the diamond wheel in a dry environment when not in use. If removing the wheel from the machine, ensure it is clean and dry before storage.
6. Troubleshooting
If you encounter issues with your Tormek DE-250 Diamond Wheel, consider the following:
- Poor Sharpening Performance: Ensure the wheel is clean and free of embedded metal particles. Verify that the correct sharpening angle is being used for your tool.
- Excessive Wear: While diamond wheels are highly durable, excessive pressure or improper use can lead to premature wear. Ensure you are using light, consistent pressure.
- Corrosion: If signs of rust appear, ensure you are consistently using the anti-rust concentrate in the water and that the wheel is dried properly after use.
