Reasons To Use a CMM

A Coordinated Measuring Machine, commonly known as CMM, is a device that manufacturers use to accurately measure and examine the geometrical properties of an item. This allows them to precisely examine that both production and prototype parts and assemblies follow the proper design. 

The CMM was invented in the 1950s. However, it kept on developing until today. A modern-day CMM is extremely useful when it comes to the manufacturing industry.  

So, should you buy or rent a CMM? The simple answer is yes. It does not matter if you need CMM retrofits or other tasks. Here are several reasons why you should consider buying or renting a high-quality CMM. 

Improved Stability 

CMMs are extremely consistent and reliable pieces of equipment with the right calibration and periodic service. CMMs usually don’t experience any problems. That is why they are an ideal upgrade and addition to your manufacturing processes.  

CMMs also have an excellent lifespan. Usually, they can last for a lot of years. This means that any upfront expenses are repaid over a much longer period compared to a lot of other manufacturing tools. You can also extend the lifespan of your machine by upgrading and retrofitting it using a high-quality company.  

 Increased Productivity 

With the other benefits that you can get with CMMs, you can ensure that your company’s productivity will greatly increase. This is particularly true when it comes to inspection processes.  

In addition to that, productivity is realized via the analytical and computational abilities of data-handling systems. This includes calculators and any type of computer.  

Reduced Influence from the Operator 

Since the machine is controlled by a computer, it can do the measurement of the same components without the help of an operator. This will lower the possibilities of errors in measurement and every part can be measured using a similar procedure.  

Excellent Accuracy 

Every measurement result comes from a single origin that is a part coordinate system with CMM. That is why these errors are reduced in general. Aside from that, it can achieve excellent accuracy compared to manual inspection processes.  


Essentially, CMMs are universal measuring machines. This means that they can do other tasks as well. They can measure the most dimensional properties of a part configuration. This includes warped surfaces, gears, and cams.  

You don’t need unique gages or fixtures. Since light is the probe contact of the machine, almost every component can be examined without being clamped to the table.  

Less Setup Time 

If you’re a manufacturer, you know how it can be extremely time-consuming to do an inspection on the surface plate. Fortunately, that will not be the case with CMM. You can align a component in 3 axes in a single go.  

You can easily orient a component in drawing direction with reference points. You can also directly compare data using drawing dimensions. This can produce part reference system extremely easily. In addition to that, you can also use operator-defined orientation. 

With the benefits above, you should not hesitate in incorporating a CMM for your operations. They’re an excellent investment.
