Manufacturing Process of Precision Turned Parts
General precision machining includes processes such as milling and drilling. Special focus will be placed on precision turned parts.

Overview of the Precision Turning Process
The general working mechanism of the precision turning process is that the workpiece rotates relative to a stationary cutting tool. The process involves:
- Mounting the workpiece onto the lathe
- Selecting suitable cutting tools
- Inspecting the workpiece and cutting tools before operation
- Choosing the optimal cutting speed and feed rate
Turning can be performed manually or automatically. For CNC machines, the turning process is well-suited for precision part manufacturing due to its automation.
Swiss machines are ideal for producing small and complex parts.
CNC Turning: A Core Technology for Precision Manufacturing
Application of CNC machines in producing precision turned parts.
CNC stands for Computer Numerical Control. It means the machine is controlled by a computer, specifically through CNC programs. On a CNC machine, the required or optimal speed, feed rate and other parameters are set in advance, and the machine runs automatically without manual operation.
CNC programming plays an essential role in precision machining. With programming, CNC machines automatically follow design parameters throughout the material removal process.
The automation of CNC machines enables the production of high-quality components with complex geometries.
