In the field of precision measurement, the tool microscope is an important instrument that cleverly integrates the magnification function of optical microscopes with precision coordinate measurement systems, and is widely used in many scenarios such as industrial manufacturing and scientific research experiments.

The working principle of a tool microscope is based on optical imaging and coordinate measurement. By illuminating the object under test with a light source, the light is magnified and imaged by the objective lens, and then further magnified by the eyepiece for human observation. The total magnification is generally between 10X and 200X. At the same time, it is equipped with high-precision coordinate measuring devices, and the stage can be precisely moved in the X and Y axis directions under the drive of precision screws or rails. The movement amount is read by rotating the dial or digital display device, and the accuracy can usually reach 1-10 microns. The stage or eyepiece can also rotate to measure angles. Nowadays, many microscopes are equipped with digital systems that can input measurement data into computers for processing.

The tool microscope has multiple practical functions. In terms of length measurement, it can accurately determine the diameter, inner hole, taper hole, hole spacing, and groove spacing; When measuring angles, the contour angles of various cutting tools and the angles of the template are not a problem; When measuring threads, geometric elements such as pitch, outer diameter, inner diameter, pitch, and tooth angle can be accurately measured; For shape verification, the shape of the template, die, cam, etc. can be verified according to Cartesian or polar coordinates.

Taking the mechanical manufacturing industry as an example, when producing shaft parts, a tool microscope can measure the diameter and cylindricity of the shaft to ensure that it meets the design requirements; In the electronics industry, small electronic component parameters such as the spacing between chip pins and the size of capacitors and resistors can be measured. In mold manufacturing, the dimensions of the mold cavity are measured using a tool microscope to ensure high-precision manufacturing of the mold. In the field of scientific research, it can help observe the microstructure of materials and provide data support for research.

Tool microscopes, with their advantages of high precision, versatility, non-contact measurement, and easy operation, have become powerful assistants for industrial testing, reverse engineering, mold and tool calibration, and play a key role in ensuring product quality and promoting scientific research progress.
