Powering Benchtop CNC Mills With Fanless Mini Computers


Benchtop CNC (Computer Numerical Control) mills are compact precision machining systems designed to automate cutting, drilling, and milling processes on a smaller scale. These machines are widely used across government, defense, aerospace, and research industries for rapid prototyping, custom part fabrication, and small-batch manufacturing. Given their high precision and ability to operate within controlled environments, benchtop CNC mills are essential tools for organizations that require repeatable accuracy in limited workspaces. With highly accurate instructions and numerous sensors required to enable these machining systems, a rugged edge computer serves as a centralized hub to consolidate these sensors and streamlines complex workloads for real-time insights.  

 

Company Background 

The CNC machining company featured in this case study specializes in designing and manufacturing benchtop CNC milling machines tailored for government and industrial sectors. Their specialty lies in their CNC software that allows their machines to efficiently deliver precision performance for advanced manufacturing capabilities. With a strong emphasis on meeting North American regulatory requirements and government-specific applications, the company focuses on delivering dependable hardware platforms to customers operating in highly regulated industries. 

Challenge 

Realizing that their previous solution was over-configured and were unsatisfied with the supplier’s support, the CNC machining company sought out an edge computing hardware partner with a replacement that can meet their deployment requirements while remaining cost-effective and compliant with government regulations.

The Challenges 

The CNC machining company previously relied on an edge computing solution that was not optimized for their workload requirements. Furthermore, they were increasingly dissatisfied with their former hardware supplier’s limited technical support. They concluded the need for a more agile hardware partner that could provide technical expertise, dedicated support, and certified hardware compliant with North American regulatory standards. 

Searching for A Dedicated Hardware Partner  

Faced with growing operational demands and a need for technical support, the company began searching for an edge computing partner capable of providing tailored solutions and responsive engineering support. Beyond performance considerations, their CNC systems required computing platforms pre-certified with UL safety standards and full compliance with NDAA (National Defense Authorization Act) and TAA (Trade Agreements Act) regulations to meet government procurement standards. 

Extensive USB Connectivity Requirements 

An essential requirement for the new computing platform was the ability to connect up to eight separate USB-based sensors, devices, and controllers. Their existing system was limited in I/O expansion, restricting their ability to scale or add new devices without significant system modifications. These peripherals included human-machine interfaces (HMI), motion controllers, data acquisition modules, and other USB-powered accessories critical for CNC operation and monitoring. 

Equipment Cabinet Constraints 

Another challenge was the extremely limited space within their CNC machine’s equipment cabinet. The existing edge computer, while compact, was tightly integrated into a space-constrained environment. The replacement system would need to maintain an ultra-compact footprint while delivering reliable performance in harsh industrial conditions, including vibration, dust, and temperature fluctuations common in manufacturing environments. 

 

The Solution: x86 Super-Rugged Fanless Mini Computer 

After thoroughly evaluating the company’s technical requirements and deployment challenges, Premio recommended its RCO-1000 Series, an x86-based super-rugged fanless mini computer designed for industrial edge computing applications. This compact computing solution addressed the company’s connectivity, reliability, and compliance requirements while maintaining a small form factor optimized for space-constrained deployments. 

EDGEBoost I/O for Extensive IoT Connectivity 

Premio's RCO-1000-EHL system was configured with an EDGEBoost I/O module, enabling four additional USB ports without increasing the system’s physical footprint. This modular approach allowed the them to meet their demanding connectivity needs for multiple USB-based devices while avoiding costly and time-consuming OEM customization. Unlike the previous computing platform, which would have required a larger chassis to support additional I/O, the RCO-1000-EHL maintained its compact design while expanding connectivity. 

Real-Time Performance 

Powered by an Intel® Atom® processor, the RCO-1000-EHL delivers a power-efficient performance architecture optimized for edge computing workloads. Its processing capabilities were more than sufficient for the their operational needs, including real-time data processing, motion control, and machine monitoring. The system supports DDR4 memory, providing a reliable and cost-effective solution with a 10-year product lifecycle a critical factor for long-term deployments in government manufacturing environments. 

Ruggedized Equipment Cabinet Integration 


The RCO-1000’s ultra-compact, fanless, and cableless design enabled seamless integration into the CNC machine’s equipment cabinet. Its robust mechanical construction ensures resistance to shock, vibration, and thermal fluctuations commonly found in industrial environments. 

Additionally, UL Listed certification was a non-negotiable requirement for the company due to their focus on government customers. Premio’s RCO-1000 Series met these critical safety standards, ensuring that the computing platform would not interfere with other sensitive electronics and met the necessary regulatory compliance for government facility deployment. 

 

Benefits of Partnering with Premio 

By partnering with Premio, the CNC machining company gained access to a trusted U.S.-based edge computing hardware manufacturer with deep expertise in industrial-grade solutions. Premio’s NDAA and TAA-compliant products provided peace of mind for government-focused applications, while their dedicated sales and engineering support teams worked closely with the customer to optimize their edge computing solution. 

An additional strategic advantage was the regional proximity between both companies  based in California. This close geographical alignment enabled faster collaboration cycles, streamlined logistics, and enhanced customer support through on-site technical consultations and rapid deployment services. Localized support was a key differentiator in reducing downtime, expediting project timelines, and fostering a collaborative engineering relationship. 

Premio’s supply chain expertise and long product life cycles ensure that customers can deploy edge computing hardware with confidence, knowing that support, serviceability, and scalability are built into the partnership.
