Vintage 75–100 mm Outside Micrometer with Rounded Measuring Tips

€150,00 EUR
This vintage outside micrometer features rounded measuring tips, also known as ball tips. Its silver-colored metal frame, finely graduated thimble and knurled controls give it the distinctive character of specialized industrial measuring equipment. According to the supplied information, this micrometer has a measuring range of 75–100 mm and graduations of 0.01 mm. It is intended for measuring external dimensions and thicknesses within that range. The graduations do not guarantee its current measuring accuracy; operation and calibration have not been confirmed. SPECIALIZED DESIGN WITH ROUNDED MEASURING TIPS Unlike an outside micrometer with two flat measuring faces, the rounded tips make localized contact with the workpiece. According to the supplied description, this design is intended for specialized measurements of curved surfaces and hollow components, depending on the shape, accessibility and dimensions of the workpiece. Tubes and hollow cylinders: The rounded tips may be suitable for wall-thickness measurements where the tube wall is accessible and its thickness falls within the instrument’s measuring range. Localized contact can help reduce the influence of surface curvature. Curved surfaces and metal profiles: The rounded tips can make contact where flat measuring faces may not seat properly. Potential applications include specialized checks on curved machine components, bearing components or hollow metal profiles, provided their geometry and dimensions suit the instrument. DESIGN AND CONDITION The photos show a metal frame, a readable graduated scale, knurled controls and black locking levers. Visible signs of use and superficial scratches are present on the metal. The maker, country of origin and year of manufacture have not been established. Please review all seven photos for the visible condition and details of this particular instrument. Operation and calibration should be checked before use for precision measurements. SPECIFICATIONS Type: Outside micrometer with rounded measuring tips Measuring range, as supplied: 75–100 mm Scale graduations, as supplied: 0.01 mm Approximate dimensions, as supplied: 23 × 12 × 3 cm Weight: 451 g A distinctive instrument for collectors of industrial measuring tools or as an addition to a technical collection.
