Building Barreto Tough: CNC Mills and Lathes

Welcome to this installment in our Building Barreto Tough Series, where we give a bit of insight into what it means to be “Built Barreto Tough.” If you are just starting this journey with us, we recommend you start here: Building Barreto Tough: Laser Department and Press Break

Hex Part CNC

This article focuses on our CNC department. An important, and rather busy, specialty in our manufacturing line!

Our CNC department affords us the ability to fabricate and machine many of our parts. We craft in-house components from bushings and bearing housings to internal and external gear parts on our lathes. We even process our own cutter wheels and hydraulic valve blocks on our mill machines. The CNC department has been an integral part of our manufacturing line for about 25 years.


As the company grew, so did our fabrication departments to meet our customer’s demands. Our CNC department now operates 7 lathes and 4 mills. Keeping up with advances in technology has given us the ability to increase our production with speed and accuracy and also allows us to control our own lead times and quality standards. When operating manually, the mill department was able to produce certain parts at rates of about 75 units per week. The machines in operation today are able to produce those same individual parts at rates of over 1,000 units per week. We average a total of 3,000 - 4,000 CNC parts per week!



In addition to production, these advanced machines provide us the ability to machine more complex parts, giving our engineers flexibility in design and allowing us to keep more of our manufacturing in house. With the expanded work-load and production, our machinists are able to learn and advance, opening up entry level positions, and offering apprenticeships to local high school students showing interest in machining and engineering.
