Reducing the scrap rate during precision CNC machining is the key to improving production efficiency, ensuring product quality and reducing production costs. The following are some effective measures and suggestions:
1. Improve equipment accuracy and stability
Choose high-precision machine tools: Use better and more accurate CNC machine tools for processing to ensure that the machine tool’s repeated positioning accuracy and precision CNC processing accuracy meet product requirements.
Regular inspection and maintenance: Regularly inspect and maintain the machine tool, including cleaning and lubrication of key components such as guide rails, slides, screws, and inspection of the electrical system to ensure that the machine tool is in good working condition.
2. Optimize processing materials and tools
Select high-quality raw materials: Select high-quality raw materials with good stability and consistent mechanical properties to reduce material errors.
Select tools reasonably: Select appropriate tools according to precision CNC processing materials and processing requirements, and optimize cutting parameters such as cutting speed, feed rate, etc. to reduce errors and vibrations during cutting.
3. Strengthen quality control and monitoring
Introduce good measuring equipment: Use high-precision measuring equipment such as trigger-type infrared online probes to monitor the size and position of workpieces in real time during processing, and promptly detect and correct errors.
Implement the first-piece inspection system: Perform full-size inspection on the first piece of each batch of products to ensure that the processing process meets the design requirements.
Set up an automatic alarm system: Set up an automatic alarm system during precision CNC processing, and stop the machine in time when the product size is abnormal or the machine tool fails to avoid more waste.
4. Optimize process flow and design
Optimize the processing process flow: Make the process flow more stable and controllable by adjusting the processing sequence, improving the clamping method, and other measures.
Reasonable product design: When designing products, the processing technology should be fully considered to avoid processing errors and waste caused by unreasonable design.
5. Improve operating skills and training
Strengthen skill training: Precision CNC machining regularly conducts skill training for operators to improve their operating skills and troubleshooting capabilities.
Promote good operating experience: Encourage operators to share and exchange advanced operating experience to improve the overall operating level.
6. Pay attention to environmental factors and detail management
Control the processing environment: Keep the temperature, humidity and cleanliness of the precision CNC processing environment stable, and reduce the impact of environmental factors on processing accuracy.
Pay attention to detail management: such as ensuring that the drawing version is updated, strictly abide by the process flow, etc., to avoid waste caused by negligence of details.
