Product Description
Precision machining of metal parts refers to the process of using specialized machinery and tools to create parts and components with extremely high tolerances and accuracy. The goal is to produce metal parts that fit precisely and function as intended, often to exact specifications.
This type of machining is used in industries like aerospace, automotive, medical devices, electronics, and more, where parts need to be made to strict standards for performance and safety.
There are several key processes involved in precision machining:
-
CNC Machining: Computer Numerical Control (CNC) machines are used to automate the machining process, allowing for precise and repeatable cuts, drills, and operations on metal parts. CNC machines can perform milling, turning, grinding, and drilling.
-
Milling: A rotating cutting tool is used to remove material from a workpiece, creating complex shapes, holes, and features.
-
Turning: Involves rotating the workpiece while a stationary cutting tool is applied to it, usually to create cylindrical shapes.
