Controlled File Distribution

Enforce Strict File Governance from Engineering to CNC Spindle

Uncontrolled distribution of CNC machine files creates significant compliance vulnerabilities across defense contracting environments. Controlink Systems LLC provides automated communication software that restricts file distribution to verified machine requests. By ensuring operators receive only engineering-approved programs without unauthorized manual tampering, facilities protect proprietary part geometry, maintain reliable version histories, and prevent unverified program modifications at the machine control.

Proven Shop-Floor Performance

Manufacturing organizations trust our communication systems to manage and safeguard machine tool communications.

"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 automated DNC software help control CNC program access?

Automated DNC software restricts file distribution by pulling requested files solely from secured central folders managed by engineering. Instead of operators copying files manually across unmonitored flash drives or network shares, requests are triggered through standardized commands, ensuring only authorized, released programs are returned directly to the CNC control.

Can machine operators still request CNC programs directly from the control?

How are program edits handled when changes are made at the machine tool?

Does this software support older legacy CNC machines alongside modern controls?

How many CNC machines can be simultaneously managed from one central computer?

Can program request notifications be forwarded via email or text message?

Is software evaluation available before deploying across a facility?

What protection plans exist for computer hardware failure?
