0.01mm Graduation Outside Micrometer 50-75mm Range Spiral Measuring Instrument For Machinist

Label:Yes The measuring range is 50 to 75mm(1.97 to 2.95in), and the accuracy can be 0.01mm(0.00in). It is a very accurate and reliable measuring tool. The precise mechanical structure locking device makes the reading more intuitive and accurate. The outside micrometer is suitable for measuring small grooves, such as drill bits, vertical milling cutters and other diameters and clock gears. The micrometer has a glossy body and adopts scale technology, which makes it glossy when sliding on the object to measure. The measuring surface of the micrometer is made of carbon steel, and the measurement is more accurate.

Item Type: Micrometer Range: Approx. 50 to 75mm(1.97 ton 2.95in) / 2 to 3in Material: Carbon steel Resolution: Approx. 0.01mm(0.00in) Error: Approx. ±0.04mm(0.00in) Measurement Type: Outer diameter measurement How to use: 1. For zero calibration, ensure that the front edge of the micrometer cylinder is aligned with the horizontal engraved line, and the main axis scale is aligned with the zero scale of the micrometer cylinder. The first step to correct the degree is to ensure that the zero calibration is correct. 2. When measuring an object, first rotate the ratchet to adjust the distance between the side drill and the side micro screw to be slightly larger than the size of the object, and put the object to be measured into it. 3. Slowly rotate the ratchet until it clicks, and the reading starts. The click indicates that it has been locked, and it is not necessary to rotate it too hard, otherwise it will cause damage. 4. First, read the graduation value of the scale line under the fixed casing with the end surface of the microtube as the guideline, and then use the horizontal line on the fixed casing as the reading guideline to read the graduation value on the movable scale. , The reading should be read to one-tenth of the minimum degree.
