Introduction

In the precision machining field of the modern manufacturing industry, precision CNC machining parts play an extremely critical role. These parts are widely used in aerospace, automobile manufacturing, medical equipment and many other industries because of their high precision and high performance. However, how to use them correctly to maximize their effectiveness is a problem that many practitioners and enterprises are very concerned about.

Pre-planning and preparation

In-depth understanding of part characteristics

Before using precision CNC machining parts, we must first have a deep understanding of its characteristics. Parts made of different materials, such as aluminum alloy, stainless steel and titanium alloy, have different physical properties such as hardness, toughness and thermal expansion coefficient, which determines the cutting parameters and cooling methods during machining. For example, titanium alloy parts have high strength but poor thermal conductivity, and are prone to high temperature during processing, so special cutting technology and cooling strategy are needed to prevent the parts from deformation or damage.

Precise matching processing equipment

According to the precision requirements and complexity of parts, it is very important to choose the appropriate CNC machining equipment. High-precision parts need to be equipped with high-precision machine tools, and their positioning accuracy, repeated positioning accuracy and other indicators must meet the processing requirements of parts. At the same time, we should also consider the processing capacity of the machine tool, such as the size of the workbench, the maximum stroke, the speed range of the spindle, etc., to ensure that the parts can be processed smoothly.

Specific operation flow

Elaborate processing program

The machining program is the core of controlling CNC machining equipment, which determines the key parameters such as tool trajectory, cutting speed and feed rate. When writing the program, we should fully consider the factors such as the shape, size and tolerance requirements of the parts, and use advanced CAD/CAM software to simulate and find out and solve possible problems in advance, such as tool interference, over-cutting or under-cutting.

Rigorous parts clamping and tool alignment

Fixing precision CNC machining parts correctly on the workbench to ensure firm clamping and accurate position is the basis of ensuring machining accuracy. When clamping, the deformation of parts should be avoided, and special clamping methods should be adopted for thin-walled parts. Tool alignment is to determine the relative position relationship between the tool and the part. Through accurate tool alignment, the size of the machined part can be guaranteed to meet the design requirements.

Monitoring of machining process

In the process of machining, it is necessary to closely monitor the running state of the equipment and the processing of parts. Through the monitoring system of the machine tool, the parameters such as spindle speed, feed speed and cutting force can be observed in real time. If any abnormality is found, such as sudden increase of cutting force and intensified spindle vibration, it is necessary to stop the machine in time for inspection and continue processing after troubleshooting. At the same time, the dimensions of parts should be measured regularly to ensure that the machining accuracy is within the allowable range.

Matters needing attention in use

Strictly control the processing environment

The machining environment has an important influence on the machining quality of precision CNC machining parts. Temperature, humidity, dust and other factors may cause deformation of parts or affect the accuracy of equipment. Therefore, the processing equipment should be placed in a constant temperature, constant humidity and clean environment to reduce the interference of environmental factors on processing.

Reasonable selection of cutting fluid

Cutting fluid plays an important role in cooling, lubrication and chip removal during machining. According to the material and processing technology of the parts, choose the appropriate cutting fluid. For example, for aluminum alloy parts, special aluminum alloy cutting fluid can be selected to improve the surface quality and tool life. At the same time, the cutting fluid should be replaced regularly to maintain its cleanliness and performance.

Conclusion

The correct use of precision CNC machining parts requires strict control of all links from pre-planning, specific operation to use. Only in this way can we give full play to the advantages of precision CNC machining parts, produce high-quality products and provide strong support for the development of manufacturing industry. With the continuous progress of technology, new methods and skills will emerge in the future when using these parts, which will push the manufacturing industry to a higher level.

As a conclusion , precision cnc machining is a necessary process to create large and small items and parts, according to strict manufacturing guidelines, specifications and key tolerances. We also provide CNC Micro Machining Parts, Swiss-Type Machining Parts.
