Product advantages of smooth plug ring gauge

High-Precision Measurement

O Accurate dimensional tolerance: Smooth plug gauges and ring gauges are manufactured according to strict international, national or industrial standards, and their dimensional tolerance is controlled within a very small range. For example, for high-precision smooth plug gauges, the diameter tolerance can reach ±0.001mm or even less.

This makes it possible to accurately judge whether the workpiece is within the tolerance range required by the design when measuring the dimensions of the inner hole or the outer circle of the workpiece. This high-precision measurement ability can ensure the accuracy of the cooling channel size of the blade in the internal hole detection of aerospace engine blades, thus ensuring the cooling efficiency and performance of the engine.

O Stable measurement repeatability: Due to its precise manufacturing technology and high-quality materials, the smooth ring gauge can keep stable measurement results after being used for many times.

Every time the plug gauge is inserted into the inner hole of the workpiece or the outer diameter of the workpiece is measured with a ring gauge, as long as the operation is standardized, the deviation of the measured results is extremely small.

For example, in the external diameter detection of piston ring of automobile engine, the use of high-quality ring gauge can ensure the repeatability of each measurement, thus ensuring the matching accuracy of piston ring and cylinder wall and reducing the engine wear and air leakage.
Strong Wear Resistance

O selection of high-quality materials: smooth plug ring gauges are usually made of alloy steel or tool steel with high hardness and wear resistance, such as Cr12MoV and GCr15. These materials have a good balance of hardness and toughness, and the hardness can reach HRC60-65 after heat treatment such as quenching and tempering.

For example, in the production of measuring tools, the ring gauge made of Cr12MoV steel has high surface hardness and can effectively resist wear after proper heat treatment.

O surface treatment process: in order to further improve the wear resistance, some smooth ring gauges will also undergo surface treatment, such as nitriding and chromium plating. Nitriding treatment can form a nitride layer with extremely high hardness on the surface, improving wear resistance and corrosion resistance.

Chromium plating can make the surface smoother, reduce friction coefficient and reduce wear. In the long-term and frequent use of machining inspection environment, the smooth plug ring gauge with surface treatment can maintain a good working condition.

For example, in the process of long-term inspection of the inner hole of metal mold, its wear rate is obviously lower than that of the measuring tool without surface treatment.
Simple Operation

O Intuitive measurement and judgment: the smooth plug gauge has a through end and a stop end. When the through end can pass through the inner hole of the workpiece smoothly but the stop end cannot, it means that the size of the inner hole of the workpiece is within the tolerance range.

Similarly, the ring gauge has a similar intuitive judgment method for measuring the outer diameter of the workpiece. This simple and direct operation mode can be quickly mastered even by operators without complicated training. For example, in a small machining factory, new workers can quickly learn to use smooth ring gauges to measure the dimensions of simple parts.

O Fast measuring process: Compared with some complicated measuring instruments, the measuring process of smooth ring gauge is very fast. In the assembly line of mass production, inspectors can quickly use the ring gauge to conduct random inspection on the workpiece, which will not have a great impact on production efficiency.

For example, when producing a large number of bolts and nuts with standard sizes, using ring gauges to detect the inner diameter of nuts and the outer diameter of bolts can complete a lot of detection work in a short time.
Strong Customization

O size customization: smooth ring gauges of various sizes can be customized according to the special needs of customers. Whether it is the inspection of the inner hole of the oversize industrial equipment (such as the inner hole of the runner of a large hydraulic turbine) or the inspection of the parts of the tiny precision instruments (such as the inner hole of a micro bearing), the appropriate plug ring gauge can be customized. Moreover, in the process of customizing the size, any tiny size value specified by the customer can be accurate to meet the special design requirements.

O Precision and shape customization: In addition to size, smooth ring gauges with different precision levels can be customized. For some parts inspection of scientific research and experimental equipment that require high precision, we can provide ultra-high precision ring gauges.

At the same time, for inner holes or excircles with special shapes (such as taper, steps, etc.), plug ring gauges with corresponding shapes can also be customized to accurately measure the dimensions of these complex shapes. For example, in the inspection of inner holes of some special molds, plug gauges designed for stepped inner holes can accurately detect the dimensions of each step.

Various Sizes And Specifications

O Wide range of standard sizes: Smooth ring gauges cover the range from extremely small sizes to extremely large sizes. In international standards, there are a complete series of sizes, such as tiny plug gauges as small as a few millimeters or even a few tenths of millimeters, which are used to detect the inner hole of precision parts such as electronic components, and ring gauges as large as several meters in diameter are used to measure the outer diameter of large mechanical structural parts.

For example, in the watch manufacturing industry, smooth plug gauges with a diameter of 1-2mm may be used to detect the inner holes of gears and other parts, while in the wind power equipment manufacturing, ring gauges with a diameter of several meters may be needed to detect the outer diameter of large wheels.

O Non-standard dimensions meet special requirements: In addition to standard dimensions, we can also produce non-standard plug ring gauges according to special design requirements of different industries.

In oil production equipment, it is necessary to customize the smooth plug gauge with non-standard size to detect the inner hole of some special specifications tubing joints. These non-standard ring gauges can be manufactured accurately according to specific engineering drawings and design parameters to meet special measurement requirements.
Strict Quality Control

O quality inspection of raw materials: in the first step of producing smooth plug ring gauge, strict quality inspection of raw materials will be carried out. Check whether the hardness, metallographic structure and chemical composition of the material meet the requirements.

For example, for steel raw materials, spectral analysis will be used to determine whether the content of various alloy elements is within the standard range, and hardness test will be used to determine whether the initial hardness is appropriate. Only qualified raw materials will enter the next production process.

O Precision monitoring in the machining process: During the machining process, high-precision machining equipment and advanced machining technology are used, and the dimensional accuracy of the ring gauge is monitored in real time through the online measuring system.

After each machining process, it should be tested. For example, after grinding, the dimensional accuracy and surface roughness should be checked by using precision measuring equipment such as three-coordinate measuring instrument. Once the dimensional deviation is found out of the allowable range, it will be adjusted or reworked to ensure the quality of each processing stage.

O Inspection and calibration of finished products: The finished smooth plug ring gauge shall undergo comprehensive inspection, including dimensional accuracy, shape error and surface quality.

At the same time, the ring gauge will be compared and calibrated with a higher standard measuring tool to ensure that its measurement accuracy is within the specified tolerance range. For high-precision ring gauge, it may be calibrated under constant temperature and humidity to eliminate the influence of environmental factors on the measurement results.
Good Stability

O temperature stability: the smooth ring gauge can maintain good dimensional stability in different temperature environments. The thermal expansion coefficient of the material is carefully selected and controlled, and the size change is very small within a certain temperature change range.

For example, in some casting workshops under high temperature environment, or in the cold storage equipment parts inspection under low temperature environment, the measurement accuracy of the smooth plug ring gauge will not be obviously deviated due to the temperature change, thus ensuring the reliability of the measurement results.

O Long-term stability: Due to its wear resistance and deformation resistance, the smooth ring gauge can maintain stable measurement performance during long-term use. Even after many frequent measurement operations, its size accuracy and shape accuracy can still meet the measurement requirements.

For example, in the long-term running automobile production line, the smooth plug gauge used to detect the inner hole of engine cylinder block and other parts can still accurately detect the workpiece size after years of continuous use, providing stable support for product quality control.

Machining Industry

O turning detection: when machining the inner hole of a part on a lathe, such as machining the central hole of a shaft part or the inner hole of a disc part, workers can use a smooth plug gauge to conduct random inspection during machining.

After machining a certain number of parts, insert the plug gauge into the inner hole, and check whether the aperture meets the design requirements by judging the on-off end. If the through end can't pass or the stop end can pass, it means that the machining size is deviated, and it is necessary to adjust the parameters of the lathe tool in time, such as cutting depth and feed rate, to ensure the dimensional accuracy of the subsequent machined parts.

O grinding quality control: in the finishing process of grinding inner hole, smooth plug gauge is an essential testing tool. Because the precision of grinding is higher, the roundness, cylindricity and dimensional accuracy of the inner hole can be accurately detected by using high-precision smooth plug gauge.

For example, when grinding the inner hole of a high-precision hydraulic valve body, the dimensional accuracy of the inner hole can be ensured to be in the micron level by using the smooth plug gauge for regular inspection, which can meet the sealing and performance requirements of the hydraulic system.

O Multi-process inspection of complex parts: For some complex mechanical parts, such as box parts with multiple inner holes, stepped holes or blind holes, smooth ring gauges are needed for inspection in different processing procedures.

After the drilling process, the plug gauge is used to preliminarily check whether the aperture meets the requirements. In the subsequent processes such as reaming and boring, the more precise plug gauge is used for testing again to ensure the size and shape accuracy of each inner hole and the assembly and use performance of the whole part.

Automobile Manufacturing Industry

O Inspection of engine parts: In automobile engine manufacturing, smooth ring gauges are widely used to inspect the inner hole and outer diameter of key parts such as cylinder block, cylinder head, piston and piston ring.

For example, when manufacturing the cylinder block, it is necessary to detect the size of each cylinder hole with a plug gauge to ensure that the fit clearance between it and the piston is within a reasonable range. For the piston ring, use ring gauge to detect its outer diameter, to ensure a good fit with the cylinder wall, and to prevent air leakage and excessive oil consumption.

O Measurement of transmission components: In the production of transmission, the inner hole and outer diameter dimensions of various gears, bushings, synchronizers and other parts need to be accurately controlled.

Smooth ring gauge is used to detect the dimensions of these parts to ensure smooth shifting and transmission efficiency of the transmission. For example, check the size of the inner hole of the transmission shaft sleeve to ensure the matching accuracy with the shaft and avoid looseness or jamming during operation.

O Quality control of automobile chassis parts: Some parts of automobile chassis, such as steering knuckle, wheel hub, etc., also need to be tested with smooth ring gauge. In the machining of steering knuckle, accurate inner hole size is very important for installing steering bearing.

Using plug gauge can ensure that the inner hole size meets the requirements and improve the stability and reliability of steering system. For the detection of the outer diameter of the hub, the ring gauge can ensure the matching accuracy with the tire, brake disc and other components.
Aerospace Industry

O Engine manufacturing and testing: Aero-engine is the key equipment in the aerospace field, and the precision of its components is extremely high. In the manufacture of engine blades, whether it is turbine blades or compressor blades, the dimensional accuracy of inner holes has an important influence on the cooling and installation of blades.

The smooth plug gauge is used to detect the size of the inner hole of the blade, to ensure that the design requirements of the cooling channel are met, and to ensure the installation accuracy of the blade on the engine rotor.

For the detection of inner hole and outer diameter of engine shaft parts and casing, it is also inseparable from the smooth plug ring gauge to ensure the high performance and reliability of the engine.

O Inspection of spacecraft structural parts: In the manufacture of spacecraft, such as the structural frame of satellite and the arrow structure of rocket, there are a large number of inner holes and outer circles that need to be accurately measured.

The dimensional accuracy of these structural parts has an influence on the overall performance, weight distribution and assembly accuracy of spacecraft. Smooth ring gauge is used to detect the dimensional changes of these structural parts during processing, to ensure that they meet the design requirements, and to ensure the safety and stability of spacecraft during launch and operation.

O aerospace precision instrument measurement: there are a large number of precision instruments in the aerospace field, such as sensors and navigation equipment in the flight control system. The inner hole and outer diameter of the parts of these instruments are usually very small and require extremely high accuracy. Using high-precision smooth ring gauge can accurately measure these tiny parts, ensure the performance and reliability of the instrument, and thus ensure the smooth progress of aerospace tasks.
Measurement And Testing Institutions

O Gauge calibration service: Metrological testing institutions provide calibration services for various measuring tools for enterprises. As a standard measuring tool, the smooth ring gauge is used to calibrate internal diameter measuring tools such as internal diameter dial indicator, internal diameter dial indicator and lever dial indicator.

By comparing these calibrated measuring tools with the smooth ring gauge with known accuracy, the zero position of the measuring tools is adjusted and their measurement errors are calibrated to ensure the accuracy of the measuring tools in enterprise production testing.

For example, for the inner diameter dial gauge sent by a mechanical processing enterprise, the measuring and testing organization uses high-precision smooth plug gauge to calibrate it in full range, so as to ensure that the error in measuring inner holes of different sizes is within the specified range.

O Verification of measuring tools in enterprises: The measuring and testing institutions are responsible for regular verification of measuring tools used by enterprises. The smooth plug ring gauge is an important verification tool when verifying the inner diameter measuring tool.

By using ring gauges with different sizes and precision grades, the measuring tools of enterprises are verified according to national or international measurement standards to judge whether the measuring tools are qualified.

If the deviation between the measurement result of the measuring tool and the standard dimension of the smooth plug ring gauge exceeds the allowable range, the measuring tool is judged to be unqualified, and the enterprise is required to repair or replace it to ensure the accuracy of the measurement data and the product quality in the production of the enterprise.

O Establish measurement standard system: Smooth ring gauge is an important part in the standard system construction of measurement and testing institutions.
