Tungsten Carbide Double-Ended Smooth Plug Gauge

A Tungsten Carbide Double-Ended Smooth Plug Gauge—also known as a Go/No-Go Gauge—is a high-precision inspection tool used to verify the dimensional accuracy of holes, bores, or cylindrical components in manufacturing and quality control processes. Constructed from solid tungsten carbide, these gauges offer exceptional wear resistance and dimensional stability, making them ideal for high-volume and tight-tolerance applications.

Key Features

• Material: Made from cobalt-bonded tungsten carbide, providing superior hardness and wear resistance compared to tool steel.

• Design: Double-ended with one end serving as the "Go" gauge and the other as the "No-Go" gauge, allowing for quick pass/fail assessments.

• Surface Finish: Polished to a mirror-like finish to minimize friction and prevent marring of the workpiece.

• Tolerance Classes: Available in various tolerance grades to meet specific measurement requirements.

Applications

• Quality Control: Essential for in-process and final inspection to ensure components meet specified dimensional criteria.

• Tool and Die Making: Utilized in the calibration and verification of tooling components.

Advantages

• High Wear Resistance: Tungsten carbide gauges have a wear life up to 50 times longer than tool steel gauges, making them suitable for repetitive inspection tasks.

• Dimensional Stability: Low thermal expansion coefficient ensures consistent measurements even under varying temperature conditions.

• Corrosion Resistance: Inherently resistant to corrosion, reducing maintenance requirements and extending service life.

Maintenance Tips

• Regular Cleaning: Keep the gauge clean and free from debris to maintain accuracy.

• Proper Storage: Store in protective cases to prevent damage when not in use.

• Calibration: Periodically verify gauge dimensions against certified standards to ensure ongoing accuracy.

These tools are integral to maintaining quality and precision in manufacturing processes. Selecting the appropriate gauge depends on specific application requirements, including tolerance levels, measurement range, and compatibility with existing equipment.
