One of the most cost-effective ways to obtain the benefits of automation is by adding a bar feeder to a CNC lathe or other bar machine. Costing anywhere from about $10,000 to $40,000 depending on configuration, the devices can add hours of untended operating time for part volumes of a few hundred to tens of thousands.

It’s the machine tool acronym you never bother to put into words: CNC. And much of the time it’s probably OK to view your “computer numerical control” as a black box doing magic. But if you’re struggling with high-speed machining, need better surface finishes or higher accuracy, have training and retention problems, or want a better handle on your production efficiency, the answer just might be the latest iterations of those three little letters.
A new report urges the United States invest in emerging manufacturing technologies, saying the private sector can’t preserve US manufacturing by itself.
Despite the addition of more than 750,000 CNC mills in the past 15 years in the US, CNC machining job shops often hover at the bottom of the totem pole, where there’s little room for error as most bids are won by a 1–2% price variance.
