We first understand the metal gear, which mainly refers to a component with teeth on the rim that can continuously transfer motion, and at the same time belongs to a mechanical part, the appearance of this part has appeared long ago.
For this kind of gear is also composed of many structures, such as tooth, tooth groove, end face and normal surface, etc., for these small components need to conform to the structure of the entire gear, so that through these small parts combined into a completed gear, in order to play a better application in various machining. We may be very familiar with this gear in our usual life, and we can also see it in many daily tools.
After the definition of metal gear, let's look at its processing method, it as a very common mechanical parts, its processing technology is also a variety of, such as: gear hobbing machine, slotting machine gear and precision casting teeth and so on. During the processing of these parts, the dimensions of each part need to be measured in order to produce metal gears that meet the requirements of the conditions. For the measurement work of the whole processing, we can't do it by ourselves. Then we need to use some more sophisticated measuring instruments, and the emergence of visual measuring machines is a good solution to this problem.
The appearance of the visual measuring machine has brought great progress for the processing of metal gear, it can accurately measure and identify the various points, surfaces and other sizes required for gear processing, which has brought great improvements to the work, but also increased the fine mass production of the gear, so it is inseparable from the visual measuring machine in the processing of metal gear.
