How to ensure the accuracy and quality of mechanical processing in Dalian?

In modern industrial production, the accuracy and quality of mechanical processing are very important. High precision and high-quality mechanical processing products can not only improve the performance and reliability of equipment, but also extend the service life of equipment and reduce maintenance costs. So, how to ensure the accuracy and quality of mechanical processing in Dalian?

1、 Design a reasonable processing technology

The design of processing technology is the foundation for ensuring the accuracy and quality of mechanical processing. When designing the processing technology, it is necessary to fully consider factors such as the shape, size, and material of the product, and choose appropriate processing methods and sequences. For example, for parts with complex shapes, CNC machining technology can be used to improve machining accuracy and efficiency; For materials with high hardness, methods such as grinding can be used to ensure the quality of the machined surface.

At the same time, it is necessary to arrange processing procedures reasonably to avoid mutual interference between processes. For example, when machining high-precision parts, rough machining should be carried out first to remove most of the excess, and then precision machining should be carried out to ensure machining accuracy. In addition, appropriate cutting tools, fixtures, and cutting parameters should be selected based on the characteristics of the processing material to improve processing efficiency and quality.

2、 Select high-precision processing equipment

The accuracy of processing equipment directly affects the precision and quality of mechanical processing. Therefore, when choosing processing equipment, priority should be given to high-precision and high-performance equipment. For example, equipment such as CNC machining centers and precision grinders have high machining accuracy and stability, which can meet the machining requirements of high-precision parts.

At the same time, regular maintenance and upkeep of processing equipment should be carried out to ensure that its accuracy and performance are in good condition. For example, regularly checking the accuracy indicators of equipment, adjusting and repairing equipment errors in a timely manner; Regularly replace the vulnerable parts of the equipment to ensure its normal operation.

3、 Strictly control the machining process

In the process of mechanical machining, it is necessary to strictly control the machining process to ensure machining accuracy and quality. Firstly, the processing temperature should be strictly controlled. Excessive processing temperature can cause part deformation and affect processing accuracy; Low processing temperature will increase cutting force and affect tool life. Therefore, the appropriate cutting fluid and cooling method should be selected according to the characteristics of the processing material and processing requirements, and the processing temperature should be controlled.

Secondly, the processing force should be strictly controlled. Excessive processing force can lead to part deformation and tool wear, affecting machining accuracy and quality; If the processing force is too small, it will affect the processing efficiency. Therefore, appropriate cutting tools and cutting parameters should be selected based on the characteristics of the processing material and processing requirements to control the machining force.

In addition, vibration and noise during the processing should be strictly controlled. Vibration and noise can affect machining accuracy and surface quality, and also pose a threat to the health of operators. Therefore, effective vibration reduction and noise reduction measures should be taken, such as installing vibration reduction pads and using low-noise cutting tools.

4、 Conduct strict quality inspections

Quality inspection is an important link in ensuring the accuracy and quality of mechanical processing. Strict quality inspection should be conducted during the machining process in Dalian to promptly identify and resolve any issues that arise during the machining process. The content of quality inspection includes dimensional accuracy, shape accuracy, surface quality, and other aspects.

For the detection of dimensional accuracy, measuring tools, coordinate measuring instruments and other equipment can be used for measurement; For the detection of shape accuracy, equipment such as profilometers and roundness meters can be used for measurement; For the detection of surface quality, equipment such as roughness meters and microscopes can be used for observation.

At the same time, a sound quality inspection system should be established to clarify the standards and methods of quality inspection, ensuring the accuracy and reliability of quality inspection. For parts that fail the inspection, they should be reworked or scrapped in a timely manner to ensure the quality of the product.

5、 Improve the technical level of operators

The technical level of operators directly affects the accuracy and quality of mechanical processing. Therefore, it is necessary to strengthen the training and management of operators, improve their technical level and sense of responsibility. Operators should be familiar with the performance and operation methods of processing equipment, master the requirements and quality standards of processing technology, and strictly follow the operating procedures for operation.

At the same time, it is necessary to strengthen the safety awareness education of operators, improve their safety awareness and self-protection ability. Operators should wear labor protection equipment correctly, comply with safety operating procedures, and ensure safety during the operation process.

In short, ensuring the accuracy and quality of mechanical processing in Dalian requires starting from designing reasonable processing techniques, selecting high-precision processing equipment, strictly controlling the processing process, conducting strict quality inspections, and improving the technical level of operators. Effective measures should be taken to continuously improve the accuracy and quality of mechanical processing, providing high-quality mechanical processing products for modern industrial production.
