Dovetail Angle Gauge

Dovetail Angle Gauge: Precision Tool for Angular Measurement.

In precision machining and manufacturing, the Dovetail Angle Gauge serves as an indispensable instrument for measuring and verifying dovetail joints—specialized interlocking structures widely used in machinery, tools, and mechanical assemblies. This precision tool ensures the accuracy of angular dimensions critical to the functionality and fit of mechanical components.

Construction and Design

Crafted from high-hardness steel or stabilized alloy, Dovetail Angle Gauges feature a robust, wear-resistant construction to maintain measurement integrity over time. The tool typically consists of a fixed reference base and an adjustable measuring blade or slider, calibrated with precise angular graduations (usually in degrees or minutes). Many models include a locking mechanism to secure settings once the correct angle is established, preventing accidental adjustments during use.

Working Principle

The gauge operates on the principle of direct comparison, using its precision-ground surfaces to match the angle of dovetail features. Users position the gauge against the workpiece’s dovetail edges; the adjustable component slides to align with the angled surfaces, while the graduated scale displays the exact angle measurement. Some advanced models integrate digital readouts for instant, high-precision results.

Applications and Significance

Widely utilized in toolmaking, mold manufacturing, and precision engineering, this gauge ensures dovetail joints meet strict tolerances. It is essential for verifying lathe beds, machine slides, and toolholders where accurate dovetail angles guarantee smooth movement, load distribution, and component longevity. Its portability and ease of use make it a staple in quality control inspections and on-machine measurement processes.

Angle: 45 degrees, 50 degrees, 55 degrees, 60 degrees. Or supply according to the angle required by each unit.
