The anvil is shaped like a flat surface, while the spindle is shaped like a curved surface that fits the contour of the spherical surface being measured. The digital readout provides precise measurements in digital format, which can be easily recorded and analyzed.

One of the key advantages of Digital Spherical Face Micrometers is their ability to measure the dimensions of spherical surfaces with high accuracy and repeatability. They typically have a measuring range of up to 1” or 25mm, and can measure dimensions to within a thousandth of an inch or a hundredth of a millimeter.

Digital Spherical Face Micrometers may also come with additional features such as data output capabilities, zero-set buttons, and locking mechanisms to prevent unintentional movement during measurement.

Overall, Digital Spherical Face Micrometers are essential tools for ensuring the precise measurement of spherical or rounded surfaces in a variety of industrial and manufacturing applications. Their unique anvil and spindle configuration allows for accurate measurements of even the most complex spherical shapes, and their digital readout provides quick and easy analysis of measurement values.
