Understanding CNC Routers with Rotary Axis

What is a CNC Router with a Rotary Axis?

A CNC router with a rotary axis is a computer-controlled cutting machine designed for 3D engraving, carving, and shaping of cylindrical or irregular stone workpieces. Unlike standard CNC routers that work on flat surfaces, a rotary axis allows the spindle to rotate the material, enabling precise multi-sided carving.

How to Optimize Stone Cutting with a CNC Router & Rotary Axis?

1. Select the Right Cutting Tools

• Use diamond-tipped router bits for durability and precision.
• Choose tools based on stone hardness and desired finish.

2. Properly Secure the Stone Workpiece

• Ensure stable clamping to prevent movement during engraving.
• Position the material correctly for accurate cutting paths.

3. Optimize Cutting Speeds and Feed Rates

• Adjust speeds based on stone density – harder stones require slower speeds for precision.
• Set the correct feed rate to prevent tool damage and ensure smooth cutting.

4. Maintain the CNC Router and Rotary Axis Regularly

• Clean the rotary axis and tool holders after each use.
• Lubricate moving parts to prevent wear and tear.
• Check for bit sharpness and tool alignment to maintain accuracy.

5. Use High-Quality CNC Software for Design and Execution

• CAD/CAM software allows for precise design planning before cutting.
• Optimize toolpaths to reduce tool wear and enhance efficiency.
