Precision CNC vertical turning of double-column brake hubs usually involves multi-axis control, high-precision cutting and complex contour processing. The following is the general process and characteristics of the double-column brake hub precision CNC vertical lathe:

1. CNC programming: Based on the design and requirements of the double-column brake hub, the operator needs to write a CNC program. This program includes tool path, cutting parameters, workpiece coordinate system and other information.

2. Clamping and positioning: On the CNC vertical lathe, the double-column brake hub needs to be clamped in place. The clamping system ensures that the workpiece is securely held and prevents movement during cutting.

3. Tool selection and installation: Select the appropriate tool according to the processing needs to ensure that the edge part of the tool can cover the entire processing area. The cutting tools should be installed correctly to ensure stable operation of the cutting tools.

4. Multi-axis control: The CNC vertical lathe has a multi-axis control function, which can control multiple axes such as the spindle, feed axis, and turret at the same time to achieve multi-directional processing and adapt to the processing needs of the complex shape of the double-column brake hub.

5. High-precision cutting: The high-precision control system of the precision CNC vertical lathe ensures accuracy during the cutting process, avoids error accumulation, and ensures the size and surface quality of the brake hub.

6. Automation functions: Some CNC vertical lathes are equipped with automatic tool changing systems, automatic measurement systems and other automation functions to improve production efficiency and reduce manual intervention.

7. Processing monitoring: During the processing process, the operator can monitor cutting status, workpiece size and other information through the CNC system, and adjust parameters or intervene in a timely manner.

8. Safety considerations: Safety is a key factor during the entire processing process. Ensure tool paths and clamping system designs are safe to avoid accidents.

9. Quality control: Precision CNC vertical lathes are usually equipped with quality control systems to ensure that the processed double-column brake hubs meet design and quality standards.

Using a precision CNC vertical lathe to process double-column brake hubs can improve production efficiency, reduce production costs, and ensure consistent product quality. Before operation, processing parameters need to be carefully set to ensure correct procedures, as well as necessary safety and quality controls.
