What Is Pin Gauges?
Pin Gauges are gauges mainly used to measure the inside diameter of holes in products and to determine whether the size of a hole passes or fails a standard.
Usually, multiple pin gauges of different thicknesses are sold as a set, and when measuring hole diameters with a length measuring machine such as a 3-point micrometer, where the results can be read numerically, variations occur depending on the skill of the person taking the measurement.
Pin Gauges, however, allow stable measurement regardless of the skill level of the measurer, thereby reducing measurement variation.
Applications of Pin Gauges
Pin Gauges are used in the processing and inspection processes of industrial products. The inside diameter of a particularly small hole cannot be measured with a measuring instrument such as a 3-point micro. Therefore, a pin gauge is used to judge the pass/fail of the hole diameter
Pin Gauges are used to measure the size of the inside diameter of a hole, but they can also be used to measure the distance between two holes. Insert a pin gauge that can be inserted without backlash into each of the two holes, measure the outer diameters of the two pin gauges with a vernier caliper, and subtract the radii of the two pin gauges to find the distance between the centers of the two holes.
Pin Gauges are also used to measure gears. One of the parameters used to evaluate the thickness of a gear tooth is the overpin dimension, in which two Pin Gauges are placed between the gears and the distance between the outer diameters of the pins is measured. The same measurement is used for internal gears to evaluate the thickness of the gear teeth.
Principle of Pin Gauges
Pin Gauges are a type of measuring gauge.
Pin Gauges are strictly controlled not only in terms of outside diameter, but also in terms of roundness and cylindricity. Since they are made with extremely high precision, the inside diameter of the target hole can be determined by inserting the gauge into the hole to be evaluated. For example, the bore diameter of a hole into which a 3.05mm Pin Gauges can pass and a 3.10mm Pin Gauge cannot be inserted is determined to be 3.05~3.10mm.
Other Information on Pin Gauges
1. How to Handle Pin Gauges
When handling Pin Gauges, be careful of the temperature. Most Pin Gauges are small in diameter and not large in volume. When handled for long periods of time, body temperature will cause Pin Gauges to thermally expand.
If thermal expansion occurs, the pin Gauges will have a larger diameter than the indicated value. Pin Gauges are very simple cylindrical pins, but they must be handled with care. For example, if the surface is scratched, it will not be possible to make a correct evaluation.
Even more important than scratches, a particular concern is rust. In the case of steel or superalloy Pin Gauges, touching them with bare hands can lead to rust formation due to the salt from the moisture contained in sweat.
It is advisable to wear gloves when handling metal Pin Gauges, or to wipe them off with a clean, soft cloth or leather after handling them with bare hands, and then apply a light coat of antiseptic oil.
2. Difference From a Pin Gauge
Similar to Pin Gauges, a plug gauge is a measuring instrument that is inserted into the hole to be evaluated. A plug gauge has two cylinders with different sizes on both ends, and by making each end a go-side and a stop-side, it is possible to quickly judge whether the inside diameter of the hole to be inspected is within the standard range.
Since the plug gauges can inspect the inside diameter of a hole relatively quick and easily, they are widely used for holes with larger inside diameters than Pin Gauges.
3. Material of Pin Gauges
Pin Gauges are made of steel, cemented carbide, or ceramic.
Ceramics are easy to maintain. Since it is not metal, there is no need to worry about rust formation. However, it is important to handle them with care, and not to treat them roughly just because they do not rust.
