When CNC lathes process wheel, drum and disk workpieces, they need to consider the geometric shape, dimensional accuracy and surface quality requirements of the workpiece. Here are some key considerations when machining wheel and drum workpieces on a CNC lathe:

1. Tool selection: Select a tool suitable for processing drum and disc workpieces, taking into account the material, shape and cutting tasks of the workpiece. Different tool shapes, different cutting edge geometries and tool coatings can affect machining results.
2. Cutting parameters: Set the correct cutting parameters, including cutting speed, feed speed and cutting depth. The selection of these parameters should be adjusted according to the workpiece material and processing requirements to ensure cutting efficiency and processing quality.
3. Clamping method: Choose an appropriate clamping method to ensure that the workpiece is stably fixed during processing. The clamping force should be moderate to prevent deformation and ensure processing accuracy.
4. CNC program design: Develop a reasonable CNC program, including tool path planning, working mode and cutting sequence. Considering the special shape of drum and disc workpieces, reasonable CNC program design can improve processing efficiency and reduce cutting load.
5. Cooling lubrication: Ensure sufficient cooling lubrication to reduce cutting temperature, extend tool life, and maintain the quality of the machined surface. For some special materials, it may be necessary to select a specific type of cutting fluid.
6. Measurement and inspection: Carry out timely measurement and inspection during the processing to ensure the dimensional accuracy and surface quality of the workpiece. This can be achieved through the use of sensors, measuring instruments and automatic measurement functions of CNC systems.
7. Reasonable setting of workpiece clamping points: When processing wheel, drum and disk workpieces on a CNC lathe, ensure that the workpiece clamping points are reasonably arranged to avoid excessive deformation or vibration during the cutting process.
8. Processing sequence optimization: Consider adopting a reasonable processing sequence to reduce process difficulty, reduce cutting residue, and improve processing efficiency.

During the entire machining process, operators need to pay close attention to the operation of the CNC system and promptly detect and handle any abnormalities. Perform regular maintenance on CNC lathes, including lubrication, inspection of key components, and tool replacement, to ensure normal operation of the equipment. By comprehensively considering these factors, efficient, precise and stable machining of wheel, drum and disc workpieces can be achieved.
