Angle Measuring Device for Semi-Rigid Coax Bend Angle Measurement and Inspection
Built for both shop-floor and lab environments, the AM40 delivers consistent, repeatable results while supporting delicate coax components during measurement.
Measure semi-rigid coax bend angles in seconds—directly at the machine without relying on a CMM.
The AM40 Angle Measuring Device from Winton Machine is designed for fast, precise semi-rigid coax bend angle measurement in high-spec production environments where accuracy and repeatability are critical.
In semi-rigid coax applications, even small deviations in bend angle can impact fit, routing, and performance. The AM40 enables operators, engineers, and quality teams to verify bend angles immediately—during setup, first article inspection, and in-process production.
Instead of relying on manual tools or waiting on metrology equipment, the AM40 provides fast, repeatable bend angle inspection for coax assemblies directly at the point of production.
Used in RF, microwave, aerospace, and high-performance electronics manufacturing, the AM40 helps maintain precision without slowing throughput.

What industries use semi-rigid coax bend angle measurement?
Why not use a CMM for coax bend angle measurement?
What Is an Angle Measuring Device for Semi-Rigid Coax?
An angle measuring device for semi-rigid coax is used to verify bend angles on small-diameter coax assemblies during setup, first article inspection, and in-process production.
Unlike manual tools or centralized inspection equipment, it allows operators to measure bend angles directly at the machine with speed and repeatability.
This enables consistent quality while maintaining production efficiency.
Why Bend Angle Accuracy Matters in Semi-Rigid Coax Applications
Semi-rigid coax assemblies are used in applications where precision is critical, including RF, microwave, aerospace, and defense systems.
Small variations in bend angle can lead to:
- Misalignment during assembly
- Routing and fitment issues
- Potential performance inconsistencies
Accurate bend angle verification improves repeatability, reduces scrap, and ensures consistent performance across production.
A “Third Hand” for Semi-Rigid Coax Measurement
Measuring small-diameter coax manually can be difficult and inconsistent.
The AM40 acts as a stable support platform:
- Lay coax assemblies directly on the device
- Support delicate components during measurement
- Verify angles quickly with repeatable accuracy
This improves both operator efficiency and measurement consistency.
Designed for Small-Diameter Coax and Precision Applications
The AM40 is ideal for small-diameter tubing and semi-rigid coax applications where precision is required.
It is particularly well-suited for:
- Semi-rigid coax assemblies
- Tight-tolerance components
- High-repeatability production environments
