Best Feeler Gauge for Precision Mechanical Applications
In high-precision mechanical systems and applications, a small amount of measurement error can have major adverse effects on system performance and cause premature parts wear or failure of the entire system. For this reason, a feeler gauge is considered to be an important measuring instrument. The feeler gauge is used to measure the width of narrow gaps, spaces, and tolerances. It is used extensively in automotive and CNC machining, tool rooms and industrial servicing and maintenance. When selecting a feeler gauge it is important to ensure that the gauge you select will provide the best measurements, repeatability over the life of the product, and consistent uptime throughout mechanical operations.
What Is a Feeler Gauge?
is a precision measuring tool made of thin metal strips that are each of a known thickness. The thicknesses can be used in a variety of combinations or alone to measure the width of gaps between two parts and may have many practical uses, including measuring valve clearances, spark plug gaps, and bearing tolerances. Additionally, they can be used to align mechanical components when assembling them together. Technicians and engineers rely on the simple yet effective design and affordable cost of feeler gauges and find them to be an essential tool in their day-to-day activities.
Importance of Feeler Gauges in Mechanical Applications
Precision mechanical systems must ensure that their components fit tightly together and are positioned accurately. Small deviations in clearance (space between two parts) can lead to the development of excessive friction, vibration and heat, as well as damaging the component. Professional feeler gauges allow users to measure and confirm the amount of clearance as well as determine how well multiple components interact with one another to ensure proper assembly, maintenance or inspection. From tuning engines to setting up CNC machines, feeler gauges help ensure that each of the systems operate at their design tolerances.
Common Feeler Gauge Use Across Industries
Across many different industries, many uses and applications of feeler gauges exist; for instance, auto repair centers utilize feeler gauges to identify the size of the valves (valve lash), as well as the amount of misalignment between the spark plugs. Additionally, feeler gauges provide a standard within most industries for assessing whether the machine (or component) is aligned correctly (or not) and whether it will mate with other components correctly during assembly. For example, CNC machinists use feeler gauges to check for tool offsets between tools and to ensure correct machine setup.
Understanding Feeler Gauge Least Count
A feeler gauge measures thickness using its least count to determine increments of thickness that are less than or equal to the smallest thickness the gauge can measure. The least count of a feeler gauge will usually be in the range of 0.01mm – 0.05mm based on the blade set (High-Quality); however, feeler gauges with lower least counts allow for greater accuracy, making them useful for producing parts that require tight tolerances such as aerospace components and high-speed engines as well as for tooling that needs to be made with high precision.
Types of Feeler Gauges Available
There are a number of different types of feeler gauges available for different purposes. The straight blade feeler gauge has the most versatility and is generally considered the most popular. The tapered gauge is designed for measuring narrow or irregular shaped gaps and the offset gauge is used when there are hard to reach areas. The combination feeler gauge is designed to allow for multiple gauges to be stacked together, allowing for a greater range of measurement thicknesses. The correct selection of a specific type will assist you in providing an easier to use and a more accurate feeler gauge.
Material Quality and Blade Accuracy
The performance of a feeler gauge will generally be dependent on the quality of the metal used for its blades. Most professional feeler gauges are manufactured using hardened stainless steel or alloy steel because these materials are durable and resistant to corrosion. The thickness of each blade has been accurately measured during the manufacturing process, and the blades are all produced with consistent tolerances on the blades so that they will produce reliable measurements after repeated usage. The use of inferior material can cause bent blades, worn-out blades, and provide inaccurate results.
How to Choose the Best Feeler Gauge
When choosing a feeler gauge, consider the overall quality of the blade, thickness of the blade and how you will be using the gauge to determine which feeler gauge is best for your needs. Check to see that all thicknesses are distinctly labelled, that the edges of the blades are smooth and that there is a protective coating applied to the blade to avoid rusting. If you intend to use a feeler gauge in a CNC or industrial setting, find a feeler gauge that offers a wide selection of thicknesses as well as a fine least count (smallest increment). Ergonomically designed feeler gauges allow for increased ease of use through improved ease of handling and stability of the blade while being held securely in place.
Accuracy and Calibration Considerations
Precision measuring tools must provide accurate measurements, as precision is critical in measurement. The thickness of an accurate feeler gauge should not change due to long-term use. Periodic verification of gauge accuracy can be accomplished by using known standards or standard reference points. Most professional operation workshops choose branded feeler gauges as these comply with international measurement standards, enabling them to provide consistent results and accurate measurements.
Feeler Gauge Use in Automotive Applications
The use of feeler gauges is an essential element in the automotive mechanic’s toolbox to set valve clearance, check spark plug gap, and check the distance between brakes. Using feeler gauges correctly will allow for smoother engine operation, lower noise levels, improved gas mileage, and extended life to engine components by eliminating excessive wear and tear on them.
Feeler Gauge Use in CNC and Industrial Machining
When used in conjunction with CNC machines or industrial machine tools (such as lathes or milling machines), a feeler gauge is an essential tool for checking proper placement of tools or for determining if the machine (and everything associated with it) is aligned correctly. A feeler gauge can be used by machinists during both setup and inspection to ensure that everything is aligned with precision. Although digital measuring devices are available, it is still a widely accepted practice among machinists to use feeler gauges when quickly verifying clearances on the floor of a shop.
Durability and Maintenance of Feeler Gauges
Durable feeler gauges can last a very long time if they are properly maintained. To help protect the gauge from rust, the user should clean and lightly oil the blades after every use. The gauge should be stored in its original travel or protective case to prevent bending or contamination. The user should also regularly inspect the gauges for blade damage and/or excessive wear prior to using them to ensure continued accuracy in measurements over time.
Understanding Feller Gauge Price in the Market
Various brands, materials, sizes of blades, and precisions are available for price comparison for a Feller Gauge. In general, the lowest priced Feller gauges are suitable for occasional use, while the highest priced Feller Gauge is the best performer. Investing in a quality Feller Gauge is beneficial, as they have a longer lifespan and provide more accurate measurements over time than lower priced Feller Gages.
Benefits of Using High-Quality Feeler Gauges
Quality feeler gauges deliver accuracy, reliability, and longevity through precise measurement, consistent performance, and enhanced durability. Quality feeler gauges are less likely to cause measurement errors that result in mechanical failure or the need to redo work. For the professional user, a dependable feeler gauge will enhance their efficiency, provide greater confidence while working, and improve the quality of their work. For the professional user, a dependable gauge will add measurable value to their work, whether it be in automotive repair or industrial machining.
