CNC vertical lathe is a machine tool widely used in the processing of parts such as gears, brake discs and hubs. Precise machining of these parts can be achieved through the high precision and efficiency of CNC vertical lathes. The following are the general steps for machining gears, brake discs and hubs by CNC vertical turning:

Gear processing:
1. Design the gear cutter profile and number of teeth, and prepare the required cutters.
2. Select the appropriate tool and install it on the tool holder of the CNC vertical lathe.
3. Clamp the workpiece on the spindle and ensure that the position and angle between the workpiece and the tool are correct.
4. Set the required cutting parameters such as speed, feed rate and depth of cut through CNC programming.
5. Start the processing process, and the CNC vertical lathe will automatically cut according to the preset program to complete the gear processing.

Brake disc processing:
1. Prepare the brake disc material and clamp it on the CNC vertical lathe according to the design requirements.
2. Choose a suitable tool and install it on the tool holder. Typically turning tools are used for cutting operations.
3. Set NC programming, including cutting parameters and processing paths, etc.
4. Start the processing process, and the CNC vertical lathe will cut according to the preset program to complete the processing of the brake disc.

Wheel hub processing:
1. Prepare the wheel hub material and clamp it on the CNC vertical lathe.
2. Select the appropriate cutting tool and install it on the tool holder.
3. Set NC programming, including cutting parameters and processing paths, etc.
4. Start the processing process, and the CNC vertical lathe will automatically execute the preset program to complete the processing of the wheel hub.

It is worth noting that each specific workpiece and processing requirements may be slightly different, so processing steps and parameters may be adjusted. In actual operation, it needs to be adjusted and optimized according to specific conditions. In addition, in order to ensure the quality and accuracy of processing, reasonable process planning, tool selection and CNC programming are very important. It is recommended to plan and prepare carefully before processing, and to fully understand the operation manual and related equipment parameters of the CNC vertical lathe used.
