Publish Time: 2024-11-21
To maintain ultra-high precision in complex shape processing, Non-Standard Precision Machining Lathe Parts needs to use advanced technology and strict quality control measures.
1. High-precision machine tools
Choosing high-precision and high-rigidity CNC lathes is the basis for ensuring processing accuracy. Modern CNC lathes are equipped with high-precision linear guides, ball screws and high-dynamic response servo motors, which can achieve micron-level positioning accuracy and repeatability.
2. Advanced CNC systems
Advanced CNC systems (such as Fanuc, Siemens, etc.) have high-speed and high-precision interpolation control capabilities. Accuracy in complex shape processing can be ensured through precise tool path planning and real-time compensation. The CNC system should also support multi-axis linkage control to achieve complex surface processing.
3. Precision tools and tool management
Use high-precision, high-wear-resistant tools (such as carbide tools, PCD tools, etc.), and regularly inspect and maintain the tools to ensure their stability and accuracy during the processing. The tool management system can monitor the status of the tool in real time, automatically compensate for tool wear, and ensure the consistency of processing accuracy.
4. Thermal stability design
The thermal deformation of machine tools and workpieces is an important factor affecting processing accuracy. The machine tool should adopt thermal stability design, such as using thermal symmetric structure, thermal compensation system, etc. to reduce the impact of thermal deformation. The workpiece clamping system should also have good thermal stability to ensure the position accuracy of the workpiece during processing.
5. High-precision measurement and feedback
During the processing process, high-precision measuring equipment (such as laser interferometer, three-coordinate measuring machine, etc.) is used for real-time measurement and feedback. Through online measurement and closed-loop control system, the processing parameters can be adjusted in real time to ensure the stability of processing accuracy.
6. Processing process optimization
For complex shape processing, the best processing path and cutting parameters are determined through process optimization and simulation analysis. Adopt a multi-process, multi-tool processing strategy, perform rough processing and finishing in stages, gradually approach the final shape, and improve processing accuracy.
7. Environmental control
The temperature, humidity, vibration, and dust of the processing environment have a significant impact on the processing accuracy. Through the environmental control system, maintain constant temperature and humidity, reduce vibration and dust, and provide stable environmental conditions for high-precision processing.
8. Quality control and inspection
During the processing process, implement strict quality control measures such as first-piece inspection, online inspection, and final inspection. Use high-precision inspection equipment to comprehensively inspect the size, shape, and surface quality of the workpiece to ensure that it meets the design requirements.
9. Workpiece clamping and positioning
The workpiece clamping system should have high precision and high rigidity to ensure the positioning accuracy of the workpiece during the processing. Use advanced fixture design and pneumatic and hydraulic clamping systems to improve clamping force and stability and reduce processing errors.
10. Tool path planning and compensation
For complex shapes, accurately plan the tool path to avoid tool interference and overcutting. Correct machining errors and ensure the accuracy of the final shape by compensating tool paths and cutting parameters in real time.
Non-Standard Precision Machining Lathe Parts maintains ultra-high precision in complex shape machining, which requires the comprehensive use of high-precision machine tools, advanced CNC systems, precision tools and management, thermal stability design, high-precision measurement and feedback, machining process optimization, environmental control, quality control and inspection, workpiece clamping and positioning, and tool path planning and compensation. Many technologies and strategies.
