Callies Performance Stays Ahead of the Competition Using FaroArms

Callies Performance Stays Ahead of the Competition Using FaroArms

Callies Performance Products® began manufacturing high performance crankshafts in 1989. Since then, Callies has grown to be the industry leader for innovative product design. The company takes pride in staying ahead of the competition with the latest high tech design and manufacturing advantages. By utilizing the latest in computer-aided solid modeling and CNC machining centers, Callies (www.callies.com) is able to offer the best designed, highest quality crankshafts available on the market today.

Callies crankshafts are at the top of the industry for quality of finish and reliability. Callies’ precise, no compromise production efforts deliver dimensional accuracy that is second to none. Concentricity and surface finish are two of the most desirable features in a high performance crankshaft journal. Each journal (the part of the shaft in contact with the bearing) must be perfectly concentric to its specified center-line, and journal surface lobing (microscopic peaks and valleys in the journal surface) must be limited to no more than .00006″ to further enhance oil film integrity at high engine speeds.

At Callies, every crankshaft is 100-percent inspected for critical dimensions, and the manufacturing equipment is constantly monitored for tolerance drift and tool degradation. For Callies, quality and durability are the driving forces behind their products.


In fact, Callies checks not only every crankshaft, but every camshaft and connecting rod they manufacture – all of these in different sizes. To check these various products, Callies previously used several measurement tools. These included a traditional fixed CMM, height gauges, micrometers, calipers, indicators, and even a spacing bench. Though every measurement situation is different and each one presents its own problems, the relative success or failure of a respective tool really comes down to its capability, speed, accuracy, and convenience.


For Callies, the convenience aspect was critical and having a measurement solution that is portable was key. With a portable solution, they can take the device directly to different locations in the shop for checking parts that can’t be brought into the QC Lab.

That convenience was realized in the FaroArm® – a portable CMM that allows for highly accurate measurement directly on the shop floor. Callies can take the FaroArm to their parts and can accurately check them for quality purposes without needing to take these parts to their QC Lab. This is not only convenient, but it also saves them the time and effort of moving parts around.

The FaroArm is very easy to understand and operate. Taking measurement points can be as easy as touching the part with the arm’s contact probe and clicking a button to record that point in 3D space. These points are calculated and recorded in software and can then be used for analysis and reporting. 

Callies uses the FaroArm on a daily basis to meet their part inspection needs for production. “The FARO is a tool that we can quickly use for general checks, or it can also be used for more complicated checks,” said Control Systems Manager Scott Lorenzen. “We have definitely benefited from the use of FARO.”

Return on Investment 

“We use the FaroArm for many different measurements and programs,” said Lorenzen. “FARO saves us a lot of time in many instances and that means it saves us money. We have seen not only reduced time and money savings, but we have also improved our processes and capabilities.”

For a company that prides itself as the industry leader, one that stays ahead of the competition through innovation, this speaks volumes. To reach their goal of quality and durability, to provide the best products on the market, Callies continues to incorporate the best manufacturing and measurement solutions – like the FaroArm.
