Milling technology ensures high precision in the following ways:

High-precision machine tool design: The design and manufacture of CNC milling machines themselves pay great attention to precision. The key components of the machine tool, such as guide rails, bearings, and spindles, all use high-precision components to ensure the basic accuracy of the machine tool.
Closed-loop control system: CNC milling machines usually use closed-loop control systems, which monitor the actual position of the tool in real time through feedback devices (such as encoders) and compare them with the command position of the CNC system. If there is a deviation, the system will automatically adjust to ensure processing accuracy.
Precision tools and fixtures: The use of high-precision tools and fixtures can reduce processing errors. The geometry, size of the tool and the accuracy of the fixture will affect the final processing results.
Precise programming: Precise programming through CAD/CAM software can ensure the accuracy of the tool path. The software can simulate the processing process and predict the interaction between the tool and the workpiece, thereby optimizing the processing parameters.
Reducing vibration: CNC milling machines improve processing accuracy by optimizing processing parameters (such as cutting speed, feed rate, cutting depth) and using vibration reduction technology to reduce vibration during processing.
Temperature control: The heat generated during the processing will affect the dimensional accuracy of the workpiece. CNC milling machines may be equipped with cooling systems, such as cutting fluid cooling, to control the temperature of the workpiece and tool and reduce the error caused by thermal expansion.
Regular calibration: Regular calibration and maintenance of CNC milling machines to ensure that all parts of the machine tool are always in the best working condition is the key to maintaining high precision.
High-quality materials: Using materials with high stability and uniformity for processing can reduce processing errors caused by the characteristics of the material itself.
Software compensation: The CNC system can automatically compensate for tool wear and machine tool errors, and adjust the processing path through software algorithms to compensate for deviations in actual processing.
