Secure Shop-Floor Automation

Eliminate USB Vulnerabilities with Centralized DNC Delivery

Relying on USB thumb drives exposes manufacturing operations to serious cyber risks, file corruption, and outdated revision errors. Our secure DNC software establishes direct, controlled communications between engineering storage and CNC machine controls. Operators request verified programs directly from their machine interface, ensuring only authorized, current files are executed while keeping production running continuously without manual data handling.

"Our daily activities in the Machine Shop have definitely become more manageable since installing Machine Link™. Machine Link™ has helped us to improve accuracy of records along with increased machine utilization. The bottom line is to say that we have overcome some big, big obstacles in our day to day..."

Steve Lisano

"Machine Link™ was easy to setup and we were able to quickly back-up all of our CNC program files from 46 different machine tools. We also, within minutes, established successful communications to a machine we had never spoken with before. It works great!"

Richard Recker

"Machine Link™ has significantly improved our productivity. We are now spending seconds doing what took us about thirty minutes before, since we had to manually enter each program. Plus, Machine Link™ is so easy to use that anybody in the shop can use it with minimal training."

Greg Scheldberg

"Machine Link™ really works well. We use its 'Search and Replace' capabilities virtually everyday. We can download a program from the control, make some quick changes, then send it right back."

Frequently Asked Questions

How does secure DNC software eliminate USB security risks?

Physical USB drives present substantial cybersecurity risks, including malware introduction and unauthorized file tampering. Modern DNC software replaces portable flash drives by routing CNC programs directly from secure engineering repositories to machine tool controls across protected serial or network connections. This ensures operators cannot introduce unvetted external media onto the shop floor.

How does automated program delivery support CMMC data governance?

Can operators request CNC programs without leaving their machines?

Can program edits made at the machine be returned to engineering?

What machine controls and communication standards are supported?

How many machines can be connected to a single computer?

Is software evaluation available before purchasing a license?

What happens if a computer running the software experiences hardware failure?
