# Nonstandard Precision Machining# Turning processing What are the characteristics of turning processing technology?

1. Wide processing range: It can process various rotary body surfaces, such as internal and external cylindrical surfaces, conical surfaces, threads, grooves, end faces, etc.

2. Higher accuracy: higher dimensional accuracy and surface roughness can be obtained. The dimensional accuracy can generally reach IT7-IT8 level, and the surface roughness can generally reach Ra1.6-Ra0.8μm.

3. High production efficiency: For mass production, the use of equipment such as multi-tool, multi-station and automatic lathes can significantly improve production efficiency.

4. The tool is simple: The structure of the turning tool is relatively simple, making it easy to manufacture, sharpen and install.

5. Good versatility: The lathe has strong versatility and can process a variety of surfaces in one clamping.

6. High technical requirements for workers: Especially when processing complex-shaped parts, workers are required to have high operating skills and experience.

7. Suitable for a wide range of materials: suitable for processing various metal materials and non-metal materials, such as steel, cast iron, copper, aluminum and engineering plastics.
