MEASURING TOOLS

The dial indicator is a gauge with a graduated dial and an indicator pointer connected to a test point by a system of levers. Any movement of the test point is magnified by the indicator pointer. The dial indicator is used to check the shape of a part, the precision of its machining, as well as for checking the accuracy of cutting machines.

Thread plug gauges or internal gauges, being of “go” and “no-go” type, are generally used for testing threads or tapped holes.

Depth gauges are used for measuring the depth of grooves and holes. Their principle of operation is similar to that of vernier calipers. A primary scale sliding in a frame may be locked in any position by a screw. The depth of a groove or a hole is measured by means of the primary scale and a vernier. Conical surfaces are measured with control gauges.

A universal angle gauge for measuring internal and external angles consists of a base with a primary scale attached to the base. A quadrant with a vernier may be moved along the arc of the base. A triangle may be attached to the quadrant by means of a holder. In its turn a detachable ruler is attached to the triangle. The triangle and the detachable ruler can be moved along the face of the quadrant. Angles can be measured within the range of 0° to 320° by means of the universal angle gauge.
