Snap Gauges: An Overview
When it comes to dimensional measurement in manufacturing, accuracy is of utmost importance. Incorrect dimensional measurements can lead to flawed batches, malfunctioning products, and safety hazards.
This is where snap gauges come into play.
Snap gauges are versatile tools used in various industries such as automotive, aerospace, medical devices, and manufacturing.
Snap gauges are a type of go/no-go gauge that provide a quick and easy way to verify whether an outside dimension of a part matches a preset dimension or falls within predefined tolerances. They are designed to be used on cylinders, shafts, grooves, and other similar parts and features in machining operations.
Types of Snap Gauges
There are several types of snap gauges available in the market for different dimensional measurement applications:
- Fixed limit Snap Gauges: These gauges assess dimensional tolerance for a single value of the dimensional parameter.
- Adjustable limit Snap Gauges: These gauges have movable anvils that can be adjusted to accommodate different part sizes.
- Combined limit Snap Gauges: These gauges have two apertures to provide Go/No-Go testing and are often arranged in a way that a part being measured can pass through the two apertures in sequence.
- Double-ended Snap Gauges: These gauges have two anvils on opposite ends, allowing for the measurement of two different dimensions.
- Dial Snap Gauges: These gauges have a dial indicator that displays the measurement reading.
- Thread Snap Gauges: These gauges are specifically used for checking the pitch diameter of screw threads.
Accuracy and Calibration
The accuracy of a snap gauge is dependent on its calibration accuracy. Calibration accuracy refers to how closely a gauge corresponds to the dimension of known standards throughout its entire measuring range.
A snap gauge with good calibration accuracy will provide more accurate measurements than one with poor calibration accuracy.
Please note that the accuracy of a gauge corresponds to the dimension of known standards throughout its entire measuring range. When making precise measurements, the goal is to reduce as many sources of error as possible and keep track of those errors that cannot be eliminated.
While snap gauges can help reduce measurement errors, the percentage of error reduction will vary depending on the specific application and the quality of the gauge being used.
Utilization and Market Growth
While there is no specific information available on how many companies worldwide utilize snap gauges as a primary tool for quality control, they are widely used in production settings where specific diametrical or thickness measurements need to be repeated frequently with precision and accuracy.
Several companies manufacture snap gauges, including Alpa Metrology, Dorsey Metrology International, JENOPTIK, MAHR, STEINMEYER, Thread Check, Mitutoyo, Glastonbury Southern Gage, Starrett, Marposs, WESTport, and Aditya.
The global snap gage market is expected to grow in the coming years, with leading companies investing in research and development to improve the accuracy and efficiency of their products.
Benefits of Snap Gauges
Snap gauges offer several benefits in dimensional measurement:
- Quick and Easy: Snap gauges provide a rapid go/no-go decision, allowing for efficient inspection and quality control.
- Versatility: Snap gauges can be used for checking dimensions on both cylindrical and non-cylindrical parts, providing flexibility in various applications.
- Cost-Effective: The use of snap gauges is generally considered to be a cost-effective investment, with potential time and cost savings compared to other types of gauges.
- Time Savings: Snap gauges can be used to measure workpiece ODs while still on the machine, reducing the need for multiple gauges and saving time and effort.
Accurate dimensional measurements are crucial in manufacturing to prevent costly errors and ensure product quality. Snap gauges are versatile tools used in various industries for dimensional measurement.
While the specific percentage of error reduction with snap gauges cannot be determined, they are known to provide accurate and economical ways of making outside diameter measurements.
The accuracy of a snap gauge depends on its calibration accuracy, and the percentage of error reduction will vary depending on the specific application and the quality of the gauge being used.
Snap gauges offer several benefits, including quick and easy measurement, versatility, cost-effectiveness, and time savings.
