The fully automatic brake drum CNC vertical lathe is a CNC vertical lathe used for brake drum manufacturing. Here are the general steps and features that may be involved:

1. CNC program writing: Develop CNC programs, including the geometric information of the brake drum, cutting path, cutting parameters, etc. This is usually done through computer-aided manufacturing (CAM) software.

2. Workpiece clamping: Clamp the brake drum firmly on the workbench of the CNC vertical lathe to ensure safe and stable clamping to prevent the workpiece from moving or vibrating during processing.

3. Tool selection: Select tools suitable for cutting brake drums, which may include turning tools, drilling tools, etc.

4. Coordinate system setting: Set the coordinate system of the CNC system to ensure that the tool path in the program matches the actual workpiece position.

5. Process parameter setting: Set cutting speed, feed speed, cutting depth and other processing parameters to adapt to the material and requirements of the brake drum.

6. Automated operation: Start the CNC program to realize fully automated brake drum processing. May include turning, drilling, turning internal holes and other processes.

7. Automatic measurement and compensation: CNC systems usually have automatic measurement functions that can detect tool wear and automatically compensate to maintain machining accuracy.

8. Cooling and Lubrication: Use coolant to cool the tool and workpiece while providing lubrication to reduce friction.

9. Quality inspection: After completing the processing, conduct quality inspection, including measuring the size of the brake drum, surface roughness, etc., to ensure that it meets the design requirements.

10. Automatic unloading: After the processing is completed, the processed brake drum will be automatically unloaded and prepared for the next round of processing.

11. Cleaning and maintenance: Clean the processing area, perform regular maintenance of the equipment, and ensure the normal operation of each component of the CNC vertical lathe.

These steps may vary depending on the design and manufacturing requirements of the brake drum. The use of fully automatic brake drum CNC vertical lathes is designed to improve production efficiency, accuracy and consistency.
