Operating Instructions
The Tormek SG-200 grindstone offers versatility for both efficient material removal and fine finishing. The grit can be adjusted using the Tormek Stone Grader SP-650.
Coarse Grinding (220 Grit)
For initial shaping, efficient material removal, or repairing damaged edges, use the grindstone in its normal 220-grit state. Ensure the stone is wet and rotate it in the direction recommended by your Tormek machine's manual. Apply light, consistent pressure with your tool against the rotating stone, using the appropriate jig.
Fine Sharpening (1000 Grit Equivalent)
To achieve a finer finish, similar to a 1000-grit stone, use the Tormek Stone Grader SP-650. Press the fine side of the Stone Grader against the rotating grindstone for approximately 30 seconds. This process polishes the surface of the grindstone, making it suitable for honing and fine sharpening. You can maintain the same jig settings as used for coarse grinding, which is a significant advantage for consistency.
Always ensure a continuous flow of water to the grindstone during operation to prevent overheating and maintain sharpening efficiency.
Maintenance
Proper maintenance ensures the longevity and performance of your SG-200 grindstone.
- Cleaning: After each use, clean the grindstone surface with a brush to remove any accumulated metal particles. This helps maintain its cutting ability.
- Dressing: Regularly dress the grindstone with the Tormek Stone Grader (SP-650) to maintain its true roundness and flatness. This is crucial for consistent sharpening results.
- Storage: When not in use, it is recommended to remove the grindstone from the water trough to prevent it from sitting in water for extended periods, which can affect its balance and performance over time. Store it in a dry place.
- Inspection: Periodically inspect the grindstone for any cracks, chips, or excessive wear. A damaged grindstone should be replaced immediately to ensure safety and optimal sharpening.
