CNC precision parts machining is a manufacturing method based on computer numerical control technology, which has the characteristics of high precision, high efficiency, and high flexibility. When machining CNC precision parts, certain guidelines and specifications need to be followed to ensure processing quality and workpiece performance. The following are some common CNC precision parts processing guidelines compiled by Dalian precision machining manufacturers:

1. Design criteria

Before machining CNC precision parts, it is necessary to carry out reasonable design. Designers should consider factors such as the characteristics of the workpiece material, the rationality of the structure, possible deformation during the processing, and accuracy requirements. At the same time, designers should also design based on the performance and process requirements of processing equipment to avoid design configurations that cannot be processed or are difficult to process.

2. Process Guidelines

CNC precision parts processing requires the development of detailed process flow and process parameters. Before processing, it is necessary to conduct sufficient process analysis and experiments to determine reasonable parameters such as cutting speed, feed rate, and cutting depth. At the same time, it is also necessary to choose appropriate cutting tools to ensure stability and efficiency during the machining process.

3. Clamping criteria

In CNC precision parts machining, the clamping of the workpiece is a very important part. Improper clamping may lead to workpiece deformation or machining errors. Therefore, when clamping, it is necessary to ensure that the clamping force of the fixture is evenly distributed to avoid problems caused by excessive tightness or looseness. At the same time, attention should also be paid to the clamping stroke and the stiffness of the fixture to ensure the stability of clamping.

4. Tool selection criteria

In CNC precision parts machining, the selection of cutting tools directly affects the machining quality and efficiency. When selecting cutting tools, it is necessary to consider factors such as workpiece material, machining type, and machining accuracy. At the same time, it is also necessary to choose the appropriate tool type and material based on the characteristics of the processing equipment and the magnitude of the cutting force.

5. Processing accuracy control criteria

An important goal of CNC precision parts machining is to obtain high-precision machining results. When processing, it is necessary to develop a reasonable machining accuracy control plan based on the accuracy requirements of the workpiece. This includes selecting appropriate processing equipment and process parameters, using appropriate measurement methods and methods for accuracy testing, and developing appropriate adjustment and compensation plans.

6. Processing monitoring criteria

In order to ensure the quality and stability of CNC precision parts processing, it is necessary to monitor and control the processing process. This includes real-time monitoring of machining parameters, tool wear, fixture status, etc., in order to promptly identify and solve potential problems. At the same time, it is also necessary to establish a reasonable recording and analysis system to comprehensively track and evaluate the processing process.

7. Quality control criteria

The quality control of CNC precision parts machining is a comprehensive process that involves multiple aspects such as material selection, process design, machining parameter control, measurement and inspection. To ensure processing quality, it is necessary to develop a comprehensive quality control plan, including the formulation of quality standards, determination of inspection processes, and handling of non-conforming products.
