Air-Gap CNC Machines and Deliver Approved Programs Automatically

Air-gapping separates machine tool controls from general corporate IT networks and the internet. By utilizing isolated wired or wireless RS-232 serial connections rather than enterprise Ethernet, legacy operating systems on CNC controls remain protected against external cyber intrusion, network malware, and unauthorized remote modifications while still exchanging part files.

Operators initiate file transfers directly from the machine console by embedding simple keywords into a small program request file. The DNC software continuously scans incoming serial lines, identifies the requested part program, and immediately returns the latest engineering-approved file back to the control without the operator leaving their station.

Yes, automated serial communication supports both legacy and modern CNC controls. Software packages like Machine Link QUICK Serve interface with any machine supporting standard RS-232 communications or behind-the-tape readers (BTR), permitting older machinery to receive automated file serving without expensive hardware replacements or enterprise networking retrofits.

Automated delivery ensures machinists receive only current, engineering-approved program revisions directly from the server. By removing uncontrolled local machine storage, manual USB drive transfers, and out-of-date paper printouts, the shop prevents operators from accidentally machining parts with outdated, unvetted G-code files.

Yes. When an operator optimizes feeds, speeds, or tooling paths at the control, the modified program can be transmitted back across the serial link. Engineering teams can review, compare, and formally adopt beneficial changes before re-approving the master file, maintaining version integrity and shop-floor safety.

Depending on the software configuration selected, a single computer can support 3, 6, 20, or up to 64 simultaneous communication sessions. Each connected CNC machine tool communicates across dedicated serial channels, allowing concurrent file transfers and continuous drip-feed operations across the entire facility.

Yes, optional Email and Text Message support allows file requests to be sent directly to the automation server. The system processes the incoming request and quickly serves the designated CNC program to the specified machine tool control, offering an ideal solution for one-way receiving controls.

Yes, Controlink Systems LLC offers a free 45-day evaluation period for Machine Link QUICK Serve products. This allows machine shops to install the software, connect their CNC controls, test automated remote program requests, and verify compatibility with existing shop hardware before purchasing.
