3. Product Overview

The Accusize Industrial Tools End Mill Grinding Fixture 2330-0050 is a hand-powered device designed for precise end mill sharpening. It utilizes 5C collets to securely hold end mills and shell mills during the grinding process. The fixture allows for grinding of various flute counts and shank diameters.

4. Setup

Proper setup is crucial for achieving accurate grinding results.

1. Mounting the Fixture: Securely mount the grinding fixture to a stable workbench or grinding machine table. Ensure it is positioned to allow for full range of motion and safe operation with your grinding wheel.
2. Inserting a 5C Collet: Select the appropriate 5C collet for your end mill's shank diameter. Insert the collet into the fixture's collet holder.
3. Inserting the End Mill: Insert the end mill into the 5C collet. Ensure the end mill is seated firmly and extends sufficiently for grinding. Tighten the collet nut to secure the end mill. The fixture is designed to grind end mills with shank diameters from 1/16" to 1-1/8".
4. Adjusting for Shell Mills: For shell mills, use a straight shank arbor to hold the shell mill, then insert the arbor into the 5C collet as described above.

5. Operating Instructions

This fixture allows for grinding of various end mill flute configurations.

1. Flute Count Selection: The fixture features a rotating dial with markings for different flute counts (2, 3, 4, 6, 8, 12). Rotate the dial to align the correct flute count with the index mark for the end mill you are grinding.
2. Positioning for Grinding: Carefully position the end mill against the grinding wheel. Ensure the grinding wheel is rotating in the correct direction and at the appropriate speed for the end mill material.
3. Grinding Process: Apply light, consistent pressure while moving the end mill across the grinding wheel. Rotate the end mill according to the selected flute count on the dial to grind each flute evenly. Repeat as necessary until the desired sharpness is achieved.
4. Checking Grind Quality: Periodically remove the end mill and inspect the grind quality. Ensure all flutes are sharp and consistent.

6. Maintenance

Regular maintenance ensures the longevity and accuracy of your grinding fixture.

• Cleaning: After each use, clean the fixture to remove grinding dust and debris. Use a brush or compressed air. Avoid using harsh chemicals that may damage the finish.
• Lubrication: Periodically apply a light machine oil to moving parts and threads to ensure smooth operation and prevent corrosion.
• Storage: Store the fixture in a clean, dry environment to prevent rust and damage.
• Inspection: Regularly inspect the fixture for any signs of wear, damage, or loose components. Address any issues promptly.

7. Troubleshooting

If you encounter issues during operation, consider the following:

• Poor Grind Quality: Check the grinding wheel for wear or glazing. Ensure the end mill is securely held in the collet. Verify that the correct flute count is selected on the indexing dial. Adjust grinding pressure and speed.
• Difficulty Rotating End Mill: Ensure the collet is not overtightened. Clean any debris from the rotating mechanism. Apply a small amount of lubricant if necessary.
• Fixture Movement: Confirm that the fixture is securely mounted to the workbench or grinding machine. Tighten all mounting bolts.
