Setup

1. Unpacking and Inspection:

   Carefully remove all components from the packaging. Inspect each part for any signs of damage during transit. If any damage is found, contact VEVOR customer support immediately.

2. Mounting the Dividing Head:

   The dividing head features a robust base designed for secure mounting to your CNC machine's work table. Use appropriate T-nuts and bolts (not included) to firmly attach the dividing head. Ensure it is aligned correctly with your machine's axis.

3. Mounting the Tailstock:

   Position the tailstock opposite the dividing head, ensuring its center height aligns with the dividing head's center. Secure the tailstock to the work table using T-nuts and bolts. The tailstock provides support for longer workpieces, preventing deflection during machining.

4. Connecting the Stepper Motor:

   Connect the numerical control cable from the dividing head's Nema23 stepper motor to your CNC controller's appropriate axis output. Ensure the connection is secure to prevent signal loss during operation.

5. Chuck Jaw Installation/Change:

   The K11-100mm chuck comes with both internal and external jaws. To change jaws, use the provided T-wrench to loosen the chuck screws, remove the current jaws, and install the desired set. Ensure jaws are properly seated and tightened before use. The internal jaws are suitable for clamping workpieces from 2-30mm, while external jaws are for 30-80mm.

Operating Instructions

1. Workpiece Clamping:

   Select the appropriate jaws (internal or external) based on your workpiece diameter. Insert the workpiece into the chuck and use the T-wrench to tighten the jaws evenly until the workpiece is firmly secured. Ensure the workpiece is centered and runs true to minimize runout.

2. CNC Program Integration:

   Integrate the dividing head into your CNC machine's control software. The 4th axis (A-axis) will allow you to program rotational movements. Utilize the 6:1 gear ratio for precise indexing and angular positioning. This ratio reduces the motor's speed, providing finer control over rotational increments and reducing vibrations.

3. Machining Operations:

   Once the workpiece is secured and the CNC program is loaded, initiate your machining operations. The dividing head will rotate the workpiece to the programmed angles, allowing for multi-sided machining, helical cuts, and other complex geometries. Monitor the process to ensure smooth operation and desired results.

Maintenance

• Cleaning:

  After each use, clean the dividing head and chuck thoroughly to remove chips, dust, and coolant residue. Use a soft cloth and a suitable cleaning agent. Avoid abrasive materials that could damage the anodized surface.

• Lubrication:

  Regularly apply a thin layer of machine oil to the chuck jaws and other moving parts to ensure smooth operation and prevent rust. Refer to your CNC machine's lubrication guidelines for compatible oils.

• Inspection:

  Periodically inspect the dividing head for any signs of wear, loose fasteners, or damage. Pay close attention to the chuck jaws, gear mechanism, and stepper motor connections. Tighten any loose bolts and replace worn parts as necessary.

• Storage:

  When not in use, store the dividing head in a clean, dry environment to protect it from dust and moisture. Applying a light coat of rust preventative oil is recommended for long-term storage.
