Product quality is of great importance today due to growing competition and changing customer preferences in the global marketplace. Industries, especially manufacturing, need advanced technological solutions to optimize workflow and increase productivity. Vision Measuring Machine (VMM) is one such technological solution that automates industrial inspections. Therefore, this article covers everything you need to know about vision measuring machines.

Sinowon automatic vision measuring machine AutoVision18122A with measuring space 1200*1800*200mm, it is quite accurate for big PCB and screen for new energy industry.

Vision Measuring Machine is an optical instrument measured by comparison method. It is necessary to establish a one-to-one corresponding length proportion relationship between the measurement software and the optical sensor under different optical magnification. Generally, the optical sensor of the VMM adopts a stereoscopic zoom lens, and the optical magnification of the lens ranges from 0.7 to 4.5X. When observing and measuring the size of the workpiece under different magnification, it is necessary to calibrate the magnification of the lens in software before measurement.

Brake disc hardness can be measured using a desktop Brinell hardness tester or a portable ultrasonic hardness tester. Today, we will compare the speed and convenience of these hardness testers to determine which one is faster and more convenient for measuring the hardness of brake discs.

​Probes used on image measuring instruments mainly include optical, laser probes and 3D contact probe. Each probe has different functions and fields of application. The functions of these three probes are expanded as follows.

The Rockwell hardness tester has advantages that make it one of the widely used hardness measurement tools. Additionally, by using different combinations of loads corresponding to different hardness scales, it can accommodate the hardness range of different materials. Sinowon Rockwell hardness testers, with patented appearance design and stable mechanical structure, mainly include three models: DigiRock HR1, DigiRock DR3, and iRock-TR1. The main differences among these three models are summarized in the following table……

The Vision Measuring Machine is a new type of precision measuring instrument based on image analysis and recognition. It is widely used due to its strong universality, large measurement range, high efficiency, high accuracy, good performance, and strong real-time capabilities. However, even precision measuring instruments like Vision Measuring Machines can produce errors during using. Therefore, instead of worrying too much, it is important to analyze the reasons behind the errors and avoid them.
