In today’s fast-paced manufacturing world, most production facilities depend on computer-controlled (CNC) equipment like lathes, mills, presses, ovens, and mixers. While these machines are built to be reliably operational, the computers that control them rarely keep pace. On average, a desktop computer has a lifespan of just 3 to 4 years. When this controller fails or becomes obsolete, a common concern is whether the entire machine will need to be replaced—a costly and disruptive process.
But what if there was another option?
In the article ahead, you will learn how Morefield working alongside of our client developed an innovative, cost-effective solution to keep a 30-year-old CNC lathe running—despite its outdated hardware, unsupported software, and lack of vendor assistance. It is a real-world example of creative problem solving, legacy system expertise, and a commitment to keeping our clients’ operations moving forward.
The Challenge: A 30-Year-Old Lathe and No Support in Sight
Our client, a manufacturer with an operational production floor, was facing a potential disruption. One of their CNC lathes—over 30 years old—was running on a computer that relied on Windows 3.1 and a proprietary file transfer system. Worse yet, the equipment manufacturer no longer existed in its original form, and there was no available support or upgrade path.
This lathe was essential to the client’s production. Replacing it would be a sizable investment, require retraining staff, and disrupt operations. The machine itself was functional. The area of concern was the outdated computer that controlled it.
This is the kind of scenario where many IT partners would throw up their hands. But at Morefield, we saw an opportunity for innovation.
Step One: Find a Working Stopgap
Our team began by digging into the technology stack behind the lathe. The first discovery was that the computer communicated using a unique file transfer process that only worked with its original software—no longer supported or compatible with modern operating systems.
After some research, we found a legacy application that could replicate the original file transfer process. However, this application required an older version of Windows to function. Fortunately, the client had a legacy PC that still ran this required version of Windows OS. We used it to test the file transfer process, and—success—the lathe could still receive and send data.
While this confirmed the viability of the workaround, we knew the solution wasn’t sustainable. The aging PC could fail, and spare parts for the older hardware would be difficult to find. Relying on this as a permanent solution was not going to work. We needed to continue the investigation and develop a solution that the client could rely on to operate the lathe
Step Two: Develop a Sustainable, Long-Term Fix
The longer-term solution would have to work on modern hardware, ensure reliable file transfer, and reduce dependence on obsolete systems. Our first instinct was to get the legacy software working natively on Windows 11, but despite best efforts and compatibility tricks, the application refused to cooperate.
That’s when we turned to Oracle VirtualBox—a powerful virtualization tool that supports older operating systems to run in a simulated environment on new hardware. This approach would allow the client to keep using the legacy application within a secure, virtualized copy of the older Windows OS—while running on up-to-date hardware.
It took time, testing, and creative problem-solving. But after tinkering with various settings, we successfully virtualized the legacy Windows environment and got the file transfer application up and running.
The final piece of the puzzle was connecting the new computer to the lathe itself. The original setup used a DB25 serial connection—an older standard. Luckily, we found a DB25-to-USB cable that was compatible with the new hardware and supported the correct data flow to the lathe. The file transfers worked, and the lathe was back in business—now supported by reliable, modern computing hardware.
Lessons Learned Along the Way
This project revealed key takeaways for other manufacturers facing similar challenges:
1. Check with the OEM (if they still exist)
If the equipment manufacturer is still in business, always consult them first. They may have established upgrade paths or replacement parts designed specifically for this kind of scenario. A supported hardware migration is almost always preferable to a custom workaround.
2. Start with Virtualization
If no OEM support is available, start by virtualizing the old OS instead of spending time trying to adapt legacy software to a new environment. Virtual machines are safer, more flexible, and reduce dependency on failing hardware.
3. Use VirtualBox to Bridge the Gap
Oracle VirtualBox proved to be a reliable tool in this case and can be used in many similar scenarios—especially where older Windows versions, serial port connections, or legacy applications are involved.
4. Modern Hardware + Legacy Software = Future-Proofing
By running old software in a virtual machine hosted on modern hardware, businesses can extend the life of their older essential machinery while maintaining security and performance standards.
Innovation in Action: The Morefield Difference
At Morefield, we believe in meeting our clients where you are—with our support you will make the smart technology decision for your operation. Our goal is to keep your business running, even when a key system is challenged, unsupported, or seemingly obsolete.
This project showcases the value of inventive thinking, deep technical experience, and a “never quit” attitude. Rather than forcing our client into an expensive and disruptive replacement cycle, we found a smart workaround that allowed them to maintain continuity in their production line—without sacrificing capability or reliability.
