A jig fixture is a custom manufacturing tool that holds and locates a workpiece, guiding cutting tools (jig) or just supporting the part (fixture) for precision, speed, and consistency in mass production, ensuring identical, interchangeable parts for operations like drilling, milling, welding, and assembly in industries from automotive to aerospace. Jigs guide the tool, while fixtures only locate the part, with jigs usually being lighter and fixtures more robust for heavier machining.      Key Functions & Benefits  

• Accuracy & Precision: Ensures parts are made to exact specifications repeatedly.
• Repeatability: Guarantees consistency across large batches.
• Increased Productivity: Speeds up operations by simplifying setup.
• Interchangeability: Parts fit together perfectly without manual adjustments.
• Operator Skill Reduction: Makes complex tasks simpler, reducing reliance on highly skilled labor. 

•  

Jigs vs. Fixtures: The Key Difference  

• Jig: Holds the workpiece and guides the cutting tool (e.g., drilling, boring).
• Fixture: Holds and locates the workpiece only; the tool's path is independent (e.g., milling, welding). 

•  

Common Applications  

• Automotive & Aerospace: Welding, assembly, engine machining.
• Medical & Pharma: Manufacturing precise components.
• Electronics: Assembly and testing. 

•  

Basic Components  

• Locating Devices: Pins or pads that position the part precisely.
• Clamping Devices: Secures the workpiece against cutting forces.
• Tool Guides (Jigs only): Bushings or templates to guide the too
