Mitutoyo 153 Series Micrometer Head

The Mitutoyo MHK-25R High Function Micrometer Head 0-25 mm Measuring Range 6715581 is an advanced measuring device widely used in engineering, manufacturing, and research settings. Its primary purpose is to provide highly accurate and fine measurements of linear displacements and dimensions. This instrument is commonly employed in conjunction with other equipment, such as calipers, height gauges, and coordinate measuring machines, to achieve precise dimensional analysis. The high function micrometer head features a compact and robust construction, incorporating precision-engineered components to ensure minimal measurement uncertainty and excellent repeatability. It consists of a spindle, which moves linearly along a precisely machined screw thread, and a thimble, which rotates to control the spindle's movement. The spindle's travel per rotation of the thimble is known as the micrometer's least count or resolution, which is typically highly precise, allowing for accurate measurements down to a few micrometers. This measuring instrument is often equipped with a ratchet or friction thimble, enabling consistent and controlled application of measuring force, thereby preventing excessive pressure on the measured object. Some high function micrometer heads incorporate a digital counter, providing a numerical readout of the measured dimension, further enhancing ease of use and reducing human errors. Maintenance and periodic calibration are critical to ensure the high function micrometer head's continued accuracy and reliability. Regular cleaning of measuring surfaces, lubrication of moving parts, and verification against certified standards are standard practices to uphold measurement integrity.
