CNC machined parts have many significant advantages, which make CNC machining technology widely used in modern manufacturing industry
High precision: CNC Machined Parts use pre programmed computer instructions to control the machine tool, achieving extremely high machining accuracy. This type of accuracy is much higher than traditional manual or mechanical processing methods, and can meet the extremely high requirements for part size and shape accuracy in applications.
High efficiency: Once CNC machine tools are programmed and set up, they can perform continuous automated processing without the need for manual intervention. This greatly improves production efficiency, reduces processing time and labor costs.
Flexibility: CNC Machined Parts technology is very flexible and can adapt to the machining needs of different shapes and sizes of parts by modifying the machining program. This enables CNC machine tools to process various complex parts without the need for machine tool replacement or tool adjustment.
High repeatability: CNC Machined Parts are based on pre programmed instructions, ensuring the same accuracy and results for each machining. This high degree of repeatability is a key factor in mass production and quality control.
Reducing human errors: Due to the automation of CNC Machined Parts, the likelihood of human errors is reduced. This helps to improve product quality and consistency, and reduce scrap rates.
Strong adaptability: CNC machine tools can adapt to the processing of various materials, including metal, plastic, wood, etc. This makes CNC machining technology widely used in different industries.
Strong machining ability: CNC machine tools can perform various machining operations, such as milling, drilling, cutting, tapping, etc. This enables CNC machining to complete complex machining tasks without relying on multiple processes or multiple machine tools.
To ensure the quality and stable performance of CNC machined parts, the following measures can be taken:
Accurate programming and design:
Ensure the accuracy of the CAD model and machining program of the parts, taking into account all dimensions, tolerances, and process requirements. When programming, fully simulate the machining process, predict potential problems, and optimize them. For example, for complex part structures, a programming strategy of multi axis linkage machining is adopted to achieve more efficient and accurate machining.
Regularly update and optimize programming software to utilize the latest features and algorithms to improve programming efficiency and accuracy.
Suitable tool and fixture selection:
Select the appropriate tool type, material, and geometric parameters based on the processing material and part shape. For example, when processing materials with high hardness, hard alloy cutting tools are selected; For thin-walled parts, use sharp cutting tools to reduce cutting force.
Design and manufacture high-precision and stable fixtures to ensure that parts are firmly fixed during the machining process without displacement and deformation. The positioning accuracy and clamping force of the fixture must undergo strict testing and verification.
High quality raw materials:
Select raw materials that meet the standards, and their chemical composition, physical properties, and mechanical properties should be stable and uniform. For example, in the aviation industry, aviation aluminum alloy materials that have undergone strict inspection and certification are used.
Strict incoming inspection of raw materials, including visual inspection, chemical composition analysis, and mechanical performance testing.
Maintenance and calibration of equipment:
Regularly maintain CNC machine tools, including cleaning, lubrication, tightening, and replacing vulnerable parts. For example, regularly check the lubrication of the screw and guide rail, and replace worn ball screws in a timely manner.
Perform precision calibration on the machine tool according to the prescribed cycle to ensure that the motion accuracy and positioning accuracy of the machine tool meet the requirements. High precision measurement equipment such as laser interferometers can be used for calibration.
