VMM is called as MÁQUINA DE MEDIÇÃO POR VISÃO, video measuring machine, optical inspect system. 

The definition of the MÁQUINA DE MEDIÇÃO POR VISÃO.

In my eyes, it is a tool that is used to measure the 2D size, such as the length, width and diameter, angle, etc. Maybe you can think of the ruler in your math class. Compared to the ruler, it is an updated measuring tool, which can meet the micron Precisão test needs. You can use this tool, exactly a kind of machine, to measure the 2D size that cannot using your eye and ruler.

It is combined by hardware and software, Which likes the parts in our body. The metal cover is his skin determine his beauty when you first saw him. The marble is his bones determine his stability. The motor is the muscle that drives all the movement. And the PC and software is the brain, the controller box is a nervous system, camera is the eyes. Like our brain order our nervous system to controll all the hardware in our body, the VMM's software order the controller box to make the slide way move, the Câmera CCD catch the image, then feedback to the software to caculat size.

In this way, it seems that it is just a simple structure, but in fact, without any of the features below, it can not achieve precision measurement.

    1.High precision granite base, column and beam ensure high stability and precision.

     2. All aluminum alloy worktable and double layer grinding optical glass.

     3. Imported high precision class linear guide, precision silent grinding screw, high precision, accurate positioning.

     4. Three axis servo motor drive.

     5. Original imported high Resolução, high Resolução industrial color CCD ensures high quality measurement picture.

     6. Imported high-definition, high-Resolução continuous Lente Zoom, can change the working Ampliação at any time

     7. Imported high precision metal linear scale.

    8. Automatic program-controlled LED cold light source can provide multi angle lighting

Except these features, the operator is also the key factor in the measuring processing. 

9. The technology and experience of the assembly engineer also determine the Precisão and stability of the machine.
