Applications

The inside micrometer is an instrument for the accurate linear measurement of the diameter, thickness, length and other dimensions of solids. 3 point internal micrometer is mainly used to measure internal dimensions such as the internal diameter of a hole or a tube and is widely used in mechanical engineering, machining and most mechanical industries.

Tips: Maintainance of the Inside Micrometer

• Please check whether the zero line of the inside micrometer is accurate.
• When measuring, the measured surface of the workpiece should be wiped clean.
• When the workpiece is large, it should be measured on a V-shaped iron or a flat plate.
• Before using an internal micrometer to measure, the measuring rod and anvil need to be wiped clean.
• Do not loosen the back cover to avoid changing the zero line.
• Do not add ordinary engine oil between the fixed sleeve and the movable sleeve.
• After using the 3-point inside micrometer, wipe it clean and oil it, put it in a special box and put it in a dry place.
