CNC Precision Machining: Process, Advantages and Applications
1、What is CNC precision machining?
CNC precision machining is a cutting-edge technology that uses instructions to automate the operation of machine tools, and can produce complex parts with high precision with minimal human intervention. In this process, a digital model of the part is first built using CAD software, and then converted into instructions that the machine tool can recognize. This precise CNC machining method can produce complex parts according to extremely strict specifications and is an indispensable part of modern manufacturing.
2、Characteristics of CNC precision manufacturing machines
1.Technology and materials
Precision engineering is built on the basis of CNC machining and is an advanced technology that integrates multiple disciplines. In order to achieve the goal of high precision and high surface quality, precision engineering requires comprehensive consideration of many factors such as processing technology, materials, equipment, testing procedures, working environment, and personnel skills. This comprehensive consideration process reflects the complexity and systematic nature of CNC precision machining, and negligence in any link may affect the final machining effect.
2.Relevance to other processes
Micromachining, ultra-fine machining, and CNC precision machining and its subcategories are closely related. In the precision machining process, many methods use special procedures such as laser cutting, which opens up new ways for the processing of high-hardness or high-durability materials.
3.Participation of automation technology
Precision and ultra-precision machining are closely related to automation technology. Automation technology plays a vital role in CNC precision machining. It can not only improve labor productivity, overall efficiency, and improve the working environment, but also has an irreplaceable role in improving machining accuracy and surface quality. Through automation technology, human errors can be effectively avoided.
4.The effectiveness of precision machining
Precision machining has high requirements, great difficulty, many variables, and many determining factors. The degree of standardization and serialization of machine tools is lower than that of traditional machine tools, and the types of tools are not enough. However, with the continuous growth of market demand, the gradual improvement of product quality requirements and the increasing maturity of technology, the popularization of high-precision CNC precision machining and the improvement of equipment utilization are gradually becoming a reality.
3、Advantages of CNC precision machining
1.High reliability
During the CNC precision machining process, the machining quality can remain stable and consistent with a large tolerance range, which not only ensures the accuracy and efficiency of machining, but also has excellent repeatability.
2.Efficiency
CNC precision machining has efficient production capabilities. It can significantly reduce the time spent on production preparation, machine tool adjustment, cutting and process inspection, thereby completing production tasks in a shorter time and maintaining high accuracy.
3.High adaptability
CNC precision machining has strong adaptability. When machining complex-shaped parts, no complex tools are required, and when part dimensions change, only modifications to the software that handles the parts are required. In addition, it can also handle contour shapes that are difficult to handle with traditional processing methods, which reflects its flexibility and superiority in processing complex parts.
4.Reduce waste
CNC machine tools are used to run the processing process with computer-controlled precision. Compared with traditional manual processing methods, it can minimize material waste and simplify the production process.
5.High product quality
It has the characteristics of high precision and high repeatability, so the parts processed are of higher quality and the tolerance range is small. This kind of high-quality parts is crucial to ensure product performance and is the goal pursued by many high-end manufacturing industries.
6.Material versatility
Able to process a variety of materials, such as metal, plastic, wood, composite materials, etc. This material versatility allows CNC precision machining to have greater flexibility in applications in different industries and can meet diverse production needs.
4、Application of CNC precision machining
1.Aerospace
It is widely used in the manufacture of aerospace components, such as engine blades, accessories and fasteners, starting parts, fuel bodies, avionics housings, side instruments, etc.
2.Automotive
