4.1 Unpacking and Inspection

Carefully unpack all components. Inspect for any shipping damage. Verify that all parts listed in the "What's in the Box" section are present:

• 8-inch Precision Horizontal & Vertical Rotary Table
• 6-inch 3-Jaw Chuck with reversible jaws
• 2 pcs Index Plates (DP-2)
• Mounting Bolts for chuck and index plates
• Chuck Key

4.2 Mounting the Rotary Table

The rotary table can be mounted horizontally or vertically on your machine tool's table. Use appropriate T-slot nuts and bolts to secure the base of the rotary table firmly to the machine table. Ensure it is level and stable before proceeding.

4.3 Attaching the 3-Jaw Chuck

1. Align the mounting holes on the back of the 3-jaw chuck with the T-slots or pre-drilled holes on the rotary table platen.
2. Insert the provided mounting bolts through the chuck and into the T-slots.
3. Tighten the mounting bolts securely to prevent any movement of the chuck during operation.
4. Familiarize yourself with the chuck key and how to open and close the jaws. The jaws are reversible for internal and external gripping.

4.4 Installing Index Plates

The index plates are used for precise angular divisions. Refer to the specific indexing instructions for your desired division. The index plates attach to the side of the rotary table mechanism.

1. Select the appropriate index plate for your desired division.
2. Mount the index plate onto the designated spindle on the side of the rotary table.
3. Secure the index plate with the provided fasteners.
4. Ensure the indexing pin engages correctly with the holes on the plate.

5. Operating Instructions

5.1 Basic Rotation

To rotate the table, loosen the dual positive action locks. Turn the handwheel to achieve the desired angular position. The satin chrome dials provide clear readings. For fine adjustments, utilize the 10-second vernier reading.

Once the desired position is reached, tighten the dual positive action locks firmly to prevent rotation during machining operations.

5.2 Using the 3-Jaw Chuck

1. Insert the chuck key into the chuck's pinion.
2. Rotate the chuck key to open or close the jaws.
3. Place the workpiece securely within the jaws. Ensure the workpiece is centered and held firmly.
4. Tighten the jaws using the chuck key. Always remove the chuck key before operating the machine tool.
5. To reverse the jaws, fully open them, remove them from their slots, flip them, and reinsert them. Ensure they are correctly seated.

5.3 Precision Indexing with Index Plates

Indexing allows for precise angular division of a circle. The DP-2 index plates provide various hole circles for different divisions.

1. Determine the required number of divisions and select the appropriate hole circle on the index plate.
2. Engage the indexing pin into the correct hole on the chosen circle.
3. Rotate the handwheel until the indexing pin aligns with the next desired hole for the division.
4. Ensure the dual positive action locks are engaged after each indexing step to maintain accuracy.

6. Maintenance

Regular maintenance ensures the longevity and accuracy of your rotary table.

• Cleaning: After each use, clean the rotary table, chuck, and index plates to remove chips, dust, and coolant residue. Use a soft cloth and a suitable cleaning agent.
• Lubrication: The gear drive is immersed in oil. Periodically check the oil level and replenish as needed with a high-quality machine oil. Lubricate all moving parts, including the handwheel mechanism and chuck jaws, with light machine oil to ensure smooth operation and prevent corrosion.
• Inspection: Regularly inspect for signs of wear, damage, or loose fasteners. Pay close attention to the worm gear, bearings, and locking mechanisms. Replace worn or damaged parts immediately.
• Storage: When not in use, store the rotary table in a clean, dry environment to prevent rust and corrosion. Apply a thin layer of rust preventative oil to all exposed metal surfaces.
