When machining ultra-high-precision parts on a CNC lathe, you may suffer from the following effects:

1. Machine tool accuracy limitations: The accuracy of CNC lathes is limited by the structure, stiffness and processing accuracy of the machine tool itself. For the processing of ultra-high-precision parts, higher-precision CNC lathes are needed to meet the processing requirements.

2. Tool selection and wear: The processing of ultra-high-precision parts on CNC lathes usually requires the use of high-precision, high-wear-resistant tools. Improper tool selection or tool wear will directly affect processing quality and accuracy.

3. Workpiece material properties: Ultra-high precision parts of CNC lathes usually require processing materials with high hardness and wear resistance, such as carbide, ceramics, etc. These special materials are difficult to process and can easily cause problems such as tool wear and processing deformation.

4. Temperature and environmental effects: During the processing of ultra-high-precision parts by CNC lathes, temperature changes and environmental factors will have an impact on the processing accuracy. For example, temperature changes can cause thermal expansion of machine tool structures, thus affecting machining accuracy.

5. Processing parameter settings: The setting of CNC lathe processing parameters is crucial for the processing of ultra-high precision parts. The selection of parameters such as cutting speed, feed speed, and cutting depth should take into account factors such as material characteristics, tool performance, and machining accuracy requirements.

6. Vibration and vibration: During high-speed processing and high-precision processing of CNC lathes, vibration and vibration will have a negative impact on the processing accuracy. Effective vibration reduction measures must be taken, such as increasing machine tool stiffness, optimizing cutting parameters, and rationally selecting tools, to reduce the impact of vibration on machining accuracy.

7. Programming and operating technology: The accuracy of CNC lathe programming and the proficiency of operating technology directly affect the processing quality and accuracy. It is necessary to ensure that the CNC program is written accurately, and the operator must be familiar with the operating procedures of the CNC lathe to ensure that the machining process is stable and accurate.

To sum up, processing ultra-high-precision parts requires comprehensive consideration of machine tool accuracy, tool selection, workpiece material properties, temperature environment effects, processing parameter settings, vibration reduction, and programming operation technology to ensure processing quality and Accuracy requirements are met.
