Optimize processing technology
Choosing the right processing technology is the basis for improving the repetitive accuracy of Precision parts processing. For different parts materials and shapes, the corresponding process methods need to be matched. For example, in milling, the use of high-speed milling technology can reduce the cutting force between the tool and the workpiece, thereby reducing the deformation of the parts and improving the consistency of processing accuracy. At the same time, the reasonable arrangement of processing procedures, such as roughing first and then finishing, and reserving a suitable margin for finishing during roughing, can also help ensure the stability of the accuracy of each processing. In addition, for some parts with complex shapes, composite processing technology can be used to combine multiple processing methods, reduce the number of clamping times, reduce the positioning error caused by multiple clamping, and thus improve the repetitive accuracy.
Improve equipment performance
High-precision processing equipment is the key to achieving repetitive precision processing of precision parts. Regularly maintain the equipment to ensure that the various performance indicators of the equipment are in the best condition. For example, checking and adjusting the guide rail accuracy of the machine tool and the clearance of the lead screw nut pair can effectively reduce the impact of the equipment's own errors on the processing accuracy. In addition, the use of advanced control systems and high-precision measurement feedback devices, such as grating rulers and laser interferometers, can monitor and compensate for errors in the processing process in real time, so that the processing accuracy can be further improved. For some key Precision parts processing, machining centers with higher rigidity and stability can also be selected to ensure that the accuracy of the equipment remains stable during long-term and large-scale processing, thereby improving the repetitive accuracy of parts processing.
Strictly control the processing environment
Precision parts processing has high requirements for the environment. Factors such as temperature, humidity, and vibration will affect the repeatability of processing accuracy. Therefore, it is necessary to strictly control the processing environment. Keep the temperature and humidity of the processing workshop relatively stable. Generally, the temperature is controlled at 20℃±2℃, and the humidity is preferably 40%-60%. This can be achieved by installing air conditioning systems and dehumidification equipment. At the same time, effective vibration isolation measures should be taken, such as using shock-absorbing pads, vibration isolation grooves, etc., to reduce the interference of external vibration on processing equipment, create a stable environment for Precision parts processing, ensure that each processing can be carried out under the same conditions, and improve repetitive accuracy.
Strengthen personnel training and management
The skill level and sense of responsibility of operators have an important impact on the repetitive accuracy of Precision parts processing. Strengthen professional training for operators so that they can master the operating skills and processing technology of processing equipment and understand the precision requirements and quality standards of Precision parts processing. At the same time, establish a complete quality management system, strengthen the monitoring and inspection of the processing process, require operators to strictly follow the operating procedures for processing, keep detailed records of each batch of parts processing, promptly discover and solve problems that arise during the processing process, and ensure the repetitive accuracy of Precision parts processing through the improvement of personnel quality and the strengthening of management.
