Redius Gauge

During the early period, there were no units for measuring thickness, which leads to the invention of the gauge.

Gauges are derived from the French word”jauge” which means the result of the measurement. We are all aware that gauges are used to measure the thickness, size or capacity of something.

Likewise, radius gauges are instruments that are used to measure the radius of the object.

The radius gauge is combined with another gauge known as fillet gauge which in mechanics means a rounding of the part design.

Radius gauge is a radius measurement tool that can be used to measure the inner radius whereas the outer radius is measured by the fillet gauge.

The construction of the radius gauge consists of two gauges having a number of steel strips or blades screwed together in one single holder. The screw is known as the lock screw.

The radius measurement is usually in metric form and measured in mm(millimeter). The material used is entirely made up of stainless steel, but a  layer or finish of satin chrome can be added since it keeps the radius gauge corrosion free and gives them more rust resistance.

The blades used are of the concave and convex shape. It may be swung out of the holder case when necessary readings need to be taken as per the requirement.

The markings are inscribed on the upper surface of every individual blade

Types of radius gauge

Three sets of radius gauge are manufactured.

  • Set 1 measure the radius available from 0.6-0.8mm.
  • Set 2 measures 1-7mm,
  • Set 3 measures 3-8.25mm.

The object or workpiece whose radius is to be measured is taken and the blades are inserted one by one to check which one fits in exactly by comparing it with the radius on the object.

Specifications of radius gauge

The radius gauge is light in weight and has an attractive design. The world keeps evolving and new and advanced technologies are taking over the old methods, hence a more optimistic and advanced gauge known as “digital radius gauge” is also available.

It is used for obtaining a high level of precision. It is a measuring tool that is user-friendly and the end user can operate it with great ease, fast since it is digital and portable.

Construction of radius gauge

T he construction of a digital radius gauge is entirely different than that of a simple radius gauge. It has a digital screen that is used to display values and for adjusting them, a measuring head and a number of brackets or jaws of different sizes ranging from 5-100mm.

The digital screen, measuring head and jaws are connected together and used. Another important aspect to be noted is that the simple radius gauge is used for measurement of small radius objects whereas the digital radius is used for larger radius measurement.
