For those who may not know, there are a variety of important machinist tools that are regularly used in industry today and one of the most important is called a go / no go gage. This kind of gage is the basic type that a snap gage is a specific version of. These are limit gages that have gaps in them which are sometimes temporary and other times permanent. By using the gaps and knowing their specific dimensions, we are much better enabled to find out if a specific part we are working with has the correct dimensions and also if it has the right kind of tolerances that we are looking for. Often, these gages have anvils inside them that are used along the edges of the gaps within the gage to do the go / no go form of testing. The material used for this purpose needs to be extremely strong in order to offer real precision and this is why carbide or tungsten is often chosen. These materials are not very likely to suffer from the wearing down that can accompany typical resistance in tools of this type. With a snap gage, you can generally recognize it by its shape. Most people will say that it looks like a letter C or perhaps a half circle or crescent.
There are different types of this form of gage and they are made in different ways. One type of snap gage is made by machining a solid piece of raw metal and then grounding it out, but keep in mind that this type is not going to be able to be adjusted once it has been made. There are gages like this which have movable anvils and they are better able to fit a variety of sizes so that they can be used for different size measuring tasks. When working with a gage of this kind that is adjustable, you generally are going to have to reset it from time to time so that you can compensate for the wear that it goes through or it may need to be re-tasked so that it will be ready to measure a different dimension. The adjustable snap gage is the one that is most often chosen because these can be bought more easily. The non adjustable variety must be fabricated which can be expensive and also consumes additional time.
If you need a snap gage like this, you will find that the web gives you plenty of places from which you can purchase one. This will make shopping for the exact gage you need a lot easier, plus you can have it shipped directly to your home or place of business. You can also order custom fabricated gages this way.
