What are CNC Jigs?

CNC jigs can be defined as devices that secure a workpiece during machining operations. They are designed to optimize the manufacturing process by providing precise positioning and support for tools. Unlike traditional jigs, CNC jigs offer automated features that enhance their functionality, allowing for complex machining tasks to be executed with ease.
Key components of CNC jigs include:
- **Base Plate**: The foundation that supports the entire jig assembly.
- **Locators**: Components that ensure the workpiece is positioned accurately.
- **Clamping Mechanisms**: Devices that securely hold the workpiece in place during machining.
- **Guide Features**: Elements that help direct cutting tools along desired paths.
These components work together to provide a stable environment for machining operations, significantly reducing the likelihood of human error and improving operational efficiency.
