Pertanyaan umum tentang VERMONT GAGE dari 3G Electric.
What is the difference between Vermont Gage Class X Go and No-Go pin gauges?
Vermont Gage Class X Go (Plus) pin gauges are used to verify the minimum allowable hole diameter; the gauge should pass through the hole. Class X No-Go (Minus) pin gauges verify the maximum allowable hole diameter; the gauge should not pass through. Class X gauges are manufactured to a tolerance of ±0.00004 to ±0.00006 inches, depending on the diameter range. Both types are made from uncoated tool steel and include a Certificate of Accuracy with NIST traceability. They are typically used in pairs for go/no-go inspection of holes and bores.
What materials are Vermont Gage pin gauges made from?
Vermont Gage pin gauges are commonly made from uncoated tool steel, which provides good wear resistance and dimensional stability. Some gauges are also available in chrome-plated steel for increased surface hardness and corrosion resistance. The choice of material depends on the application and the required lifespan of the gauge. Uncoated tool steel is standard for many Class X and Class ZZ gauges, while chrome-plated options are often selected for high-usage environments. All gauges are precision-ground to tight tolerances and come with a Certificate of Accuracy.
Are Vermont Gage pin gauge sets available in metric sizes?
Yes, Vermont Gage offers pin gauge sets in both inch and metric sizes. For example, the No-Go (Minus) pin gauge set covering 10.01 mm to 13.99 mm in 0.02 mm increments is a metric set made from uncoated tool steel. These sets are used for dimensional inspection of holes and bores, verifying that a hole does not exceed the maximum allowable diameter. Metric sets are available in various ranges and increments, and each set includes a Certificate of Accuracy with NIST traceability. Individual metric pin gauges are also available.
What is the tolerance of Vermont Gage Class X pin gauges?
Vermont Gage Class X pin gauges are manufactured to a tolerance of ±0.00004 inches for smaller diameters (e.g., 0.0751 in to 0.2810 in) and ±0.00006 inches for larger diameters (e.g., 0.7601 in to 1.0000 in). This tight tolerance ensures precise hole verification. The tolerance is specified on the Certificate of Accuracy provided with each gauge. Class X gauges are intended for applications requiring high precision, such as aerospace and medical device manufacturing. The tolerance class should be selected based on the hole size and the required inspection accuracy.
How do I select the correct Vermont Gage pin gauge for my application?
To select the correct Vermont Gage pin gauge, first determine the nominal hole diameter and the allowable tolerance. For go/no-go inspection, you will need a Go (Plus) gauge at the minimum hole size and a No-Go (Minus) gauge at the maximum hole size. Consider the gauge class: Class X offers tighter tolerances than Class ZZ. Also consider the material (uncoated or chrome-plated) and the diameter range. Vermont Gage provides detailed specifications for each gauge, including diameter, tolerance, and overall length. 3G Electric can assist with product selection and provide datasheets for verification.
Do Vermont Gage pin gauges come with a Certificate of Accuracy?
Yes, Vermont Gage pin gauges typically include a Certificate of Accuracy with NIST traceability. This certificate documents the actual measured size of the gauge and its deviation from nominal, ensuring that the gauge meets the specified tolerance. The certificate is essential for quality control and audit purposes, as it provides evidence that the gauge is calibrated and traceable to national standards. For Class X gauges, the certificate is standard. When ordering, confirm that the certificate is included, as some individual gauges may be supplied without it unless specified.
