A Boley gauge is a measuring instrument used to determine the size of watch and clock parts. It is also known as a pivot gauge. The boley gauge is made up of brass, steel, or plastic. It consists of a series of plates with holes of different sizes, into which the parts to be measured fit tightly. Its main function is to measure the diameter of wheels, pinions, and pivots. It is an essential tool for watchmakers. There are different types of boley gauges, and some of them include the following:
This is the simplest type of boley gauge. It consists of a fixed plate with holes of different sizes. The holes are drilled in the plate. The diameter of the holes is indicated on the plate. The holes have scales that allow the measurement of the parts being measured. It is easy to use and requires no special skills. It is also affordable. The disadvantage of this boley gauge is that it cannot be used to measure curved surfaces.
It is made up of two plates that are connected by a hinge. The plates have holes of different sizes, like the fixed boley gauge. The articulated boley gauge has a locking mechanism that allows the plates to be locked in place after taking measurements. It can be used to measure the thickness of curved surfaces, unlike the fixed boley gauge. It is also more accurate than the fixed boley gauge.
It consists of two rollers with calibrated scales. One of the rollers is fixed, while the other can be rotated. It is used for measuring the distance between two points. It is mostly used in the jewelry industry. The advantage of this boley gauge is that it is portable. It can also be used to measure the thickness of flat and curved surfaces.
The digital boley gauge is an advanced type of boley gauge. It has an electronic display that shows the measurement readings. This removes the stress of reading off the scales of the other types of boley gauge. It is more accurate than the other types of boley gauge.
Below are the main specifications and maintenance requirements of boley gauges.
Boley gauges are available in different types and sizes. The key specifications of each type are as follows:
It is made up of a ring with a diameter of 21mm to 27mm. The ring gauge is marked in 0.1mm increments. The ring gauge can be available in various materials, including steel and plastic.
The ball gauge has a ball diameter of 4mm to 8mm. The ball gauge is also marked in 0.1mm increments. It's made from steel or other high-quality materials.
It consists of a set of plates with notches of various widths. The notches are usually measured in millimeters. The width of plates ranges from 0.02 mm to 5 mm.
Boley gauges are made from durable materials, including hardened steel and plastic. The material used to make boley gauge impacts its accuracy and durability.
Each type of boley gauge has a different tolerance level. The tolerance level is the maximum permissible error in measurement. It is usually expressed in +/- values.
Boley gauges have different levels of accuracy. Accuracy is the ability of the gauge to provide measurements close to the true value. The accuracy of boley gauges is usually expressed as a percentage of the true value.
Boley gauges have excellent readability, which makes them easy to read. The gauges have clearly marked scales and increments.
Boley gauges have a smooth surface finish, which prevents rust and makes them easy to clean.
Boley gauges should be calibrated regularly to ensure accuracy. The calibration process involves comparing the measurements of the gauge to a standard measurement.
The measuring range of boley gauges varies depending on the type and size. For instance, the measuring range of the ball gauge is 4mm to 8mm.
Boley gauges are available in a range of sizes, each suitable for specific applications. Boley ring gauges come in sizes A to Z, with half sizes available. The sizes range from 21mm to 27mm. The ball gauge has a ball diameter of 4mm to 8mm.

It is quite easy to replace a Boley gauge without professional help. Below are the steps to follow when replacing a Boley gauge:
Q1: How can a Boley gauge be read?
A1: Reading a Boley gauge is a simple process. It involves reading the small gauge number on the left side of the tool. This is the actual measurement and it indicates the precise diameter of the material being measured. The larger gauge numbers on the right side are not used for reading and can be ignored.
Q2: What is the purpose of the Boley gauge?
A2: A Boley gauge, also known as a center gauge, is a tool used in machining to measure and check the outside diameters of cylindrical parts. It is primarily used to ensure the accuracy of turned parts in a machine shop. The Boley gauge provides a more accurate measurement of the diameter than a standard ruler or caliper, making it an essential tool for precision work.
Q3: How is caliper better than Boley gauge?
A3: Calipers and Boley gauges are used to measure the outside diameter of a round object like a cylinder. A caliper can be more versatile because it can measure the inside, outside, and depth of objects. On the other hand, a Boley gauge can measure the outside diameter of an object more precisely than a caliper can. Boley gauges are more ideal for measuring small objects like wires, whereas calipers are better for larger objects.
