From the two aspects of structure and use, we will analyze the difference between the three coordinate measuring instrument and the profiler.

Structurally,

The three coordinate measuring instrument is mainly composed of 1. mechanical system, 2. probe system, 3. electrical control hardware system, and 4. data processing software system. Profilometer structure: the profilometer consists of granite plate, worktable, sensor, drive box, display, computer and printer. In measurement, the different positions of the measured parts can be selected, the measurement length is set for automatic measurement, and the sampling data in the section can reach tens of thousands of points. It can also display or print outline shape and size, various roughness parameters and supporting length ratio curves of contour.

In terms of use,

Three coordinate measuring instrument can measure mould products, electronic products, communication, automobile and so on. It has been widely used in aerospace, automobile, electronics, mould and other industries. It is widely used in a factory, but its price is not bad.

The profile meter can measure the roughness and profile shape parameters of various precision mechanical parts. The arcs and lines are evaluated by the fitting method. Thus, the shape parameters of Garden arc radius, straightness, crown, groove center distance, inclination, vertical distance, horizontal distance, step and so on can be measured. The instrument can also test the roughness of the surface of various parts, and can test the roughness of the plane, the inclined plane, the outer cylindrical surface, the inner hole surface, the deep groove surface, the circular arc surface and the spherical surface, and measure a variety of parameters.
