  Metric pin gauge and imperial pin gauge 1. metric  pin gauge : specifications range 0.10mm ~ 50.00mm; interval: 0.005mm 0.01mm 0.02mm 0.025mm 0.05mm 0.10mm 0.50mm 1.00mm, etc.; accuracy ± 0.001mm ± 0.002mm ± 0.0005mm, etc. 2. inch pin gauge: specification range 0.011in ~ 1.000in; interval 0.001in; accuracy ± 0.001mm ± 0.002mm + 0.0025     The use of pin gauge.  Production of each product parts, first whether the tolerance size has been decided, in the upper limit and lower limit tolerance control range. Use GO (through gauge);  NO-GO gauge  (stop gauge) of the tolerance method of the gauge to implement management. For small production quantities, it is possible to reduce the cost of purchasing gauges and become proficient in their operation. It is easy to obtain the interchangeability of products, and it is very helpful in the field or in the inspection room for quality and yield improvement. In mass production, a gauge ...

What Is A Pin Gauge A pin gauge is a round bar with specific dimensions made of white steel, tool steel, ceramic, tungsten bearing steel, etc. or other materials with high hardness. It is a standardized inspection tool for holes. Appearance forms are smooth pin gauge, pin gauge with shank, titanium plated  pin gauge ,  ceramic pin gauge , and etc.. It is widely used in various fields of high precision technology such as electronic boards, circuit boards, molds and precision machinery manufacturing.   Pin Gauge Set   How to Use the Pin Gauge ​ 1. Check the measuring surface before use, there should be no rust, phi, scratches, black spots, etc.; the mark of the pin gauge should be correct and clear. 2. Remove the anti-rust oil, dust, adhesion, phi in the hole before measurement. 3. Wear gloves to operate the pin gauge according to the operation principle. 4.  The role of the pin gauge  must be in the cycle of calibration per...

  A ring gauge, also called a correction ring gauge, is a ring with specific dimensions and properties used to correct the insufficiency of a measuring tool. Ring gauges are limit gauges for shafts, mainly used to measure shafts or other external dimensions with a tolerance level of 1T6 to 1T16. The ring gauge cannot inspect the parts and crankshafts machined on the positive center, and the scope of application is limited. Ring gauges   can be divided into: smooth ring gauges, also called halo gauges, threaded ring gauges, parallel thread gauges, etc.; according to different uses and manufacturing standards, they can be divided into: standard ring gauge, SK standard ring gauge, German standard Ring gauges, pipe ring gauges, etc. According to the different manufacturing materials, there can also be ceramic ring gauges and metal ring gauges. Measurement uncertainty refers to the degree of uncertainty about the measurement results, which reflects the lack of understanding of the ...

  Plug gauges are available in several different types. These include: Go plug gauges No-go plug gauges Combination go/no-go plug gauges Go plug gauges and no-go plug gauges are called single-ended gauges and consist of a handle into which a precisely machined pin or shaft has been inserted (sometimes called a member) and which is used to verify an aspect of the dimensional tolerances of the hole. For single-ended gauges, they are usually offered in pairs with one go gauge and one no-gauge gauge. In its use, a go plug gauge is designed to test the minimum dimensional limit of the hole (i.e. the lower tolerance of the hole ’ s diameter) which represents the maximum amount of remaining material on the part or workpiece. For an acceptance condition, the go plug gauge should fit in the hole. If the go plug gauge will not fit into the hole in the workpiece, then that is an indication that the hole ’ s diameter is too small (an insufficient amount of material has been removed from the wo...

  Custom Gage Manufacturing Every machining facility in the world needs gauges to ensure that their products meet specifications. However, not every gauge is as simple as a straight plug gauge or ring gauge. Many times, a custom gage must be designed and created to measure the part. These special gauges often require the same tight tolerances as standard gauges, but have a unique geometry to fit the part design. Common plug and ring gauges have standards that must be adhered to. These standards specify tolerances, outside and inside diameters, and overall lengths. While standards are helpful, sometimes part design or fixturing requires a change in gauge characteristics. This can be as simple as adding a gauge length or as complex as spending weeks designing a gauge.     Application of Custom Gauges Why should engineers  consider custom gauges  rather than using multiple gauges? Special gauges can eliminate the extra step if multiple dimensions are to be checked....

  Ring gauge, also known as correction ring gauge , is a ring with specific size and properties used to correct the shortcomings of measuring tools. Ring gauge is a limit gauge for shaft, which is mainly used to measure shaft or other external dimensions with tolerance grade of 1t6 ~ 1t16. The ring gauge can not inspect the parts and crankshaft processed on the center, and its application scope is limited. We can also process according to your requirements.
