![]() Hardness testers are available in analog and digital bench solutions as well as compact, portable versions. Hardness and surface testers: Testing the hardness of a material is critical to determining its ability to resist form change, bending, scratching or abrasion. It is best to consult a supplier that offers a broad line as well as an extensive range of accessories to configure and position the gage, and, if needed, supply a custom-engineered indicator solution.ħ. Indicator requirements can vary widely, from checking runout to measuring tolerances in go/no-go situations, and they are used in multiple applications. Some electronic calipers are IP67 compliant. Test indicators and dial indicators, in addition to electronic or wireless indicators, are available. Indicators and gages: There are several major classes of gages, including mechanical dial, electronic display, lever-style test and back plunger. Also, IP67-compliant models are available.Ħ. The technology enables users to measure and collect error-free data to output for Statistical Process Control (SPC) analysis and much more. When measuring holes, especially when there are a large number of holes, wireless bore gages can easily collect this data. Bore gages are used to check inside diameters of holes, cylinders and pipes. ![]() Depth gages are available in varying forms, complexity, cost and accuracy, from the most accurate depth micrometers (electronic, dial and Vernier) to basic rule gages and combination rule gages.ĥ. Generally a scriber, test indicator, touch probe or CMM-style probe is used to locate the measured feature.Ĥ. Height gages are an indispensable instrument for QC, measuring the distance from a reference such as a surface plate to some feature of a part with exceptional accuracy. This Starrett W733.1 Wireless Electronic Micrometer features built-in wireless connectivity.ģ. The micrometer is one of the most accurate handheld gages. Highly specialized applications may warrant a custom-built slide caliper. Dial calipers are very popular high-accuracy, extended-range Vernier scale tools are another option. In addition to common 6" (152.4 mm), 8" (203.2 mm) and 12" (304.8 mm) tools, large, light carbon fiber models are available, as well as more specialized tools with long jaws, alternative contacts and other variations. Full-featured electronic tools, with or without IP67 protection and optional output, are available. These tools typically measure outside, inside, depth and step dimensions. Slide calipers are an essential precision measuring tool providing a large measurement range, flexibility and accuracy up to 0.001" (25.4 μm). For use in harsh shop environments where machine coolant, water, oils, dirt, dust and mist are prevalent, measuring tools with IP67-level protection ensure that precision gage accuracy, performance and functionality will remain fully intact when subjected to these elements.Ģ. Mechanical, electronic and wireless micrometers are available, including electronic models that are IP67 compliant. There are many types of micrometers depending on the application-inside, disc, blade-with outside micrometers being most commonly used. When close measurements to 0.0001" (0.00254 mm) are necessary, the micrometer is the ideal tool for the job because measurement and reading are on the same axis, and the anvil end is supported by a strong frame. Micrometers: In the hands of a skilled operator, the precision micrometer is the most accurate hand-held tool available. The following is a reference list covering the basic requirements for precision tools:ġ. Wireless electronic tools are also increasingly an option. Most gages are available in analog (mechanical readout) or electronic (digital readout with data collecting capabilities), a key requirement for SPC and measurement documentation. There is a wide range of precision measuring tools and gages that should be considered as basic requirements in a metalworking operation for ensuring good quality control (QC) processes. To ensure surface accuracy, measurements are taken on a Starrett Crystal Pink Granite Surface Plate. Starrett Test Indicators offer a swivel head feature to allow positioning to suit the technician’s line of sight from horizontal to vertical and at any angle up to 90°.
