sisähalkaisijamittarilla

Sisähalkaisijamittarilla, often translated as internal diameter gauge or bore gauge, is a measuring instrument used to determine the internal diameter of a workpiece. These tools are essential in machining, manufacturing, and various engineering applications where precise internal measurements are critical. They are designed to access and measure the internal diameter of holes, cylinders, pipes, and other hollow components.

There are several types of sisähalkaisijamittareilla, each suited for different applications and accuracy requirements. Some common types include telescopic gauges, bore gauges, and internal micrometers. Telescopic gauges have two spring-loaded plungers that extend to touch the inner walls of a bore. Once the plungers are set, the gauge is removed, and the measurement is taken with a micrometer or caliper. Bore gauges typically consist of a dial indicator mounted on a measuring head with interchangeable anvils, allowing for direct comparison of the bore's diameter to a standard. Internal micrometers offer high precision and are used for accurate measurement of internal diameters by utilizing a calibrated screw mechanism.

The selection of a sisähalkaisijamittarilla depends on factors such as the required accuracy, the size of the bore, accessibility, and cost. Proper calibration and care are crucial to ensure the accuracy and longevity of these measuring instruments. Regular maintenance, including cleaning and checking for wear, helps maintain their precision.
