Angle Heads: A Comprehensive Guide for CNC Machining

What Are Angle Heads?

Angle heads are specialized attachments for CNC milling machines, designed to add an extra axis to your machining capabilities. With an angular head, you can perform operations like drilling, milling, and tapping at various angles, enhancing your production efficiency and versatility.

Angle heads are widely used in industrial manufacturing, particularly with the rise of CNC machining. They can process a variety of materials, including wood, metal, plastic, and more.

One of the key benefits of angle heads is their ability to reduce production costs. By minimizing material waste and completing processes faster, they help streamline operations. Moreover, angular heads improve machining quality, ensuring higher precision in the final products.


Angle Head Installation: Essential Tips

Installing an angle head varies depending on the CNC machine and the head’s specifications. Here are general steps to ensure proper installation:

  1. Compatibility Check: Verify that the angle head is compatible with your CNC machine in terms of weight, dimensions, and tool magazine type.
  2. Stop Block Fit: Ensure the stop block aligns with the spindle face. Standard stop blocks often require modifications to fit properly. The stop pin of the angular head must securely enter the stop block during installation for stability and correct operation. Leave a gap of approximately 1 mm between the stop block and stop pin faces.
  3. Mounting the Angle Head: Attach the angle head to the spindle and ensure the stop pin engages with the stop block. Tighten the stop block bolts only after positioning and securing the head to the spindle.
  4. Alignment Check: Use a dial indicator to ensure proper alignment of the 360º rotating body.
  5. Operational Test: Run the angle head at low speeds to confirm proper function. Gradually increase speeds (e.g., 500 RPM for 5-10 minutes, then 1,000 RPM) to distribute grease evenly and ensure the head operates smoothly.
  6. Final Check: Verify rigidity and performance at higher speeds before commencing regular use.

Proper installation is crucial to avoid misalignments, damage to the angle head, or harm to the spindle. Always follow manufacturer guidelines for the best results.
