Three stages of development of precision testing equipment

With the continuous development of industry, precision testing instruments have also ushered in rapid development, and precision testing instruments have experienced different stages of development in China. Generally speaking, there are three major stages.

The first stage is the simple projector stage, which is the main product of the early 1990s when precision testing instruments entered the early stage of development in China. Although there was a demand for precision inspections in industry at the time, as a new industry, there were bright futures and twists and turns in development.

With the continuous development of our country's industry, the demand for testing needs has also increased. The high-precision 2D image measuring instrument leads the second stage in the development of precision testing instruments. The application of the secondary element image measuring instrument has become a new trend of detection technology, laying the foundation for complex detection.

The secondary element image measuring instrument is based on the CCD digital image and relies on the computer screen measurement technology and the powerful software capability of spatial geometric calculation. After the computer is installed with dedicated control and graphic measurement software, it becomes the measuring brain with the software's soul and is the main body of the entire device. With the development of science and technology, the measurement accuracy of various workpieces and parts is getting higher and higher, and the requirements for measuring instruments are becoming more and more demanding. The secondary element image measuring instrument is a leap forward to the traditional measurement technology and is a traditional one. The perfect combination of optical projection and computer. [

Although the secondary meta image measuring instrument has met the need of accurate measurement to some extent, there are still some deficiencies. Faced with more and more three-dimensional inspection requirements, high-end coordinate measuring machines have entered the field of vision, and precision testing instruments have entered the third phase.

The coordinate measuring machine is an instrument that can represent geometric shapes, lengths, and circumferential indexing within a hexahedral space, also known as a coordinate measuring machine or a cubic element. A coordinate measuring machine is one of the most effective methods for measuring and obtaining dimensional data because it can replace a variety of surface measurement tools and expensive combination gauges and reduce the time required for a complex measurement task from hours to minutes. The function of the coordinate measuring machine is to quickly and accurately evaluate the dimensional data and provide the operator with useful information about the status of the production process, which is very different from all manual measurement devices.

Looking at the current market of coordinate measuring machines, Hexagon has the highest market share. However, due to the acquisition of a large number of no-name manufacturers, its products have high-end and low-end points. Carl Zeiss, a typical representative of German measurement technology, is very advanced in terms of technology, but he is criticized by users for his service attitude. Other well-known brands include Zhitai Group, Hexagon (foreign production), Nikon (UK LK), EUROTONE (Europe).
