In the mechanical processing industry, machining accuracy often determines the quality of processing parts to a large extent, and CNC precision parts processing itself is a highly demanding processing method, which can achieve better results compared with the traditional processing methods. There are many advantages that other processing methods do not have, so what are the advantages of CNC precision parts processing?
1. Multi axis control linkage: in general, three-axis linkage is used most, but through some adjustment, four axis, five axis, seven axis and even more linkage axis machining center can be achieved.
2. Parallel machine tool: common machining center, its function is relatively fixed. It can combine machining center and turning center, or vertical and horizontal machining center, which can increase the processing range and processing capacity of machining center.
3. Tool damage early warning: using some technical detection means, we can find the tool wear and damage in time, and give an alarm, so that we can replace the tool in time to ensure the processing quality of parts.
4. Tool life management: multiple tools working at the same time and multiple blades on the same tool can be managed in a unified way to improve production efficiency.
5. Overload and power-off protection of machine tool: set the maximum load according to the load in the production process. When the load reaches the set value, the machine tool can realize automatic power-off to protect the machine tool.
Computer numerical control machining, referred to as CNC machining, is a subtractive manufacturing process, precision mechanical parts processing, it uses computer control to operate and manipulate machine tools and cutting tools, by removing the material layer from the workpiece to produce customized parts.
Precision CNC machining has the characteristics of automation, which greatly improves the reliability and repeatability, reduces the possibility of human error, and makes the machining of precision mechanical parts with high precision and high precision.
Precision machining technology is suitable for all kinds of materials, including metals, plastics, wood, foam and composite materials.

With the use of CNC machine tools and the development of my country's processing and manufacturing industries, the requirements for the number, precision, and efficiency of parts processing are getting higher and higher, and the demand for parts is also increasing. From the perspective of parts processing, the processing of disc-shaped thin-walled parts is more difficult than other ordinary parts, especially the processing of disc-shaped porous parts, which requires higher precision and is relatively more complex. . The machining accuracy of the parts is required to select the appropriate machine tool and determine the feasible machining path and technology in order to process and manufacture the parts that meet the requirements.
Disc-shaped porous parts have high precision requirements, which are difficult to meet with ordinary machine tools and processing techniques. Moreover, the parts are thin-walled disc-shaped parts, which are easily deformed during processing, which makes the overall accuracy requirements high and the processing difficult Therefore, in addition to the machine tool to be selected and the established processing technology program, the selection of fixtures and the clamping force must be set. After many tests and modifications, a complete set of processing plans was obtained. The test samples met the processing requirements, and the feasibility of the processing plan was determined.
1. Selection of machine tool and determination of processing method
After comparison and analysis, a coordinate boring machine with coordinate positioning device and good rigidity was selected to perform machining tasks. This machine tool has superior performance in plane milling and aperture machining. The indexing method is selected for processing the part holes. The indexing disc-type digital display turntable is installed on the machine tool worktable, and the parts are processed on the turntable, so that the different positions of the processed parts only need to rotate the turntable. When processing the hole of the part, the turntable remains fixed. The installation of the turntable is very important. The rotation center of the parts should be highly coincident with the rotation center of the turntable. During the processing, the indexing error should be controlled within a small range as much as possible.
2. Processing route
From the perspective of the process route, the processing of disc-shaped porous parts is not much different from other types of parts. The basic route is: rough machining → natural aging treatment → semi-finishing → natural aging treatment → finishing → finishing. Rough machining is to cut and mill the blank of the part, rough mill and drill the inner and outer surfaces, and both ends of the part, and rough boring the hole, and rough boring the outer groove of the part. Semi-finishing is used to semi-finish the surface of the inner and outer circles of the parts to meet the size requirements, and the two ends are semi-finished to meet the size requirements. The holes and the outer circular grooves are semi-finished boring. Finishing is the use of special fixtures and tools to fine boring the holes and external grooves of the parts. Rough turning of the inner and outer circles, and then rough milling of both ends to remove the margin, and lay the foundation for the next hole and groove finishing. The subsequent finishing process is essentially the use of special fixtures and tools to process the holes and external grooves.
The machining of parts and the setting of cutting amount are very critical, which directly affects the machining accuracy. When setting the cutting amount, it is necessary to fully consider the surface quality requirements of the parts, the degree of tool wear, and the processing cost. Boring is a process of this kind of part processing, and the setting of parameters is very important. In the process of rough boring the hole, a large amount of back-cutting is used and a low-speed cutting method is adopted. In the process of semi-precision boring and fine boring of holes, a small amount of back-grabbing should be adopted, and at the same time, attention should be paid to controlling the feed rate and adopting high-speed cutting methods to improve the processing quality of the surface of the part.
For the processing of disc-shaped porous parts, the processing of pores is not only a processing, but also a difficulty in processing, which has a direct impact on the overall processing accuracy of the part. For the processing quality and precision of such parts, it is necessary to select a suitable machine tool, a formulated process plan, a fixture to be used for clamping, a suitable tool for cutting, and proper control of the cutting amount. The sample parts processed by this processing technology meet the requirements of the parts, which lays the foundation for the subsequent mass production and processing, and also provides reference and reference for the processing of similar parts.
