“Go No Go” Rings for Quality Control: Complete Guide.
“Go no go” rings are fundamental tools for dimensional control of mechanical components. Mainly used in the manufacturing and mechanical industries, they guarantee that the parts produced comply with the required tolerances, ensuring quality and precision.
What Are “Go No Go” Rings?
They are circular gauges designed to check if a component is within the defined dimensional limits. Each set consists of two rings:
- “Go” ring: With minimum dimensions, check that the part is not undersized.
- “No Go” Ring: With maximum dimensions, it ensures that the workpiece is not oversized.
How do they work?
The use of these rings is quick and easy:
- Try with the “Go” Ring: The piece must enter without difficulty.
- Try with the “No Go” Ring: The piece must not go in.
If both conditions are met, the component complies with the specifications.
Advantages of “Go No Go” Rings:
- Simplicity and Speed: They allow immediate control without the need for numerical readings.
- Accuracy: Ideal for tight tolerances.
- Durability: Made of resistant materials, they guarantee a long service life.
Why Use Them in Quality Control?
They are essential for quickly verifying the compliance of a production batch, reducing errors and scrap costs.
If you are looking for reliable tools for dimensional control, the use of these rings are the ideal solution to ensure precision and quality in every production process.
