Difference between CNC machining and Precision machining

Difference between CNC machining and Precision machining

CNC machining (Computerized Numerical Control machining) and precision machining each have their unique characteristics in the manufacturing field, with the following main differences:

1.Different Control Methods:

• CNC machining relies on computer programs and numerical control systems to control the movement of machine tools, achieving automated and high-precision machining.
• Precision machining focuses more on achieving extremely high machining accuracy through high-precision machine tools, cutting tools, and process parameters, either manually or with the assistance of auxiliary equipment.

2.Machining Efficiency and Flexibility:

• CNC machining offers high efficiency, suitable for the machining of large batches of complex-shaped parts, and it is easy to modify programs to adapt to different designs.
• Precision machining, while also capable of handling complex shapes, typically focuses more on small batches of parts with high precision requirements, with relatively lower machining efficiency and higher skill requirements for operators.

3.Application Fields:

• CNC machining is widely used in various industries such as automobiles, aerospace, and mold manufacturing for the production of various components.
• Precision machining is more applied in fields requiring extremely high precision and surface quality, such as medical devices, optical instruments, and precision measurement tools.

4.Cost Considerations:

• The equipment cost for CNC machining is higher, but the long-term operating cost is lower due to automated production, reducing labor costs.
• Precision machining may involve more expensive machine tools, cutting tools, and inspection equipment, as well as higher training costs for operators.
