How Does CNC Turning Ensure Quality and Precision?
The accuracy and quality control of CNC turning is mainly ensured through the following aspects:
1. Equipment selection and maintenance
Use high-precision CNC lathes with regular maintenance and calibration to ensure the accuracy and stability of the machine. Modern CNC lathes with multi-axis function and advanced control system can realize higher machining precision.
2. CAD/CAM optimization
Improve machining accuracy by optimizing CAD models and CAM programming.
Reasonable design of wall thickness to avoid vibration caused by over-thinning.
Optimization of corners and edges, taking into account tool dimensions.
Control of the cavity size up to 4 times the tool diameter.
3. Process parameter control
Reasonable selection and control of cutting parameters, such as feed rate, spindle speed, depth of cut, and so on. According to different machining requirements, different process parameters such as rough turning, semi-finish turning or finish turning can be used.
4. Tool selection and management
Choose suitable high-quality tools, and regular inspection and replacement. The use of advanced tool coatings can improve surface finish and tool life.
5. Workpiece clamping
Ensure workpiece clamping is stable and accurate to minimize vibration and deviation during machining.
Through the above measures, CNC turning can realize high machining accuracy and surface quality. In general, CNC turning can achieve a surface roughness of 1.6-0.8μm. For high-precision requirements, the use of fine grinding diamond turning tool can even achieve 0.04-0.01μm “mirror turning”.
In short, the precision and quality control of CNC turning needs to be comprehensively managed from equipment, process, operation and other aspects to ensure that the machined parts meet the design requirements.
