Machine Link™
Easy-to-use CNC/DNC file transfer software that reliably sends and receives CNC programs with every RS-232-compatible machine in your shop. Edit, print, upload, and download files from a single interface.
Every minute your machinists spend walking the floor is a minute not spent making parts. Controlink Systems LLC delivers shop floor time management solutions—from CNC/DNC file transfer software to full shop-floor automation—that keep operators at their machines, reduce downtime, eliminate wasted motion, and measurably boost productivity across your entire manufacturing operation.

From entry-level CNC file transfer to full 64-machine shop-floor automation, we have a solution scaled to your operation.
Easy-to-use CNC/DNC file transfer software that reliably sends and receives CNC programs with every RS-232-compatible machine in your shop. Edit, print, upload, and download files from a single interface.
Shop-floor automation software that lets machinists request CNC files remotely without leaving their machines, continuously monitoring up to 3–64 CNC tools simultaneously to eliminate unnecessary floor walking.
Pocket PC-based CNC/DNC file transfer software providing extreme mobility for upload and download of CNC programs across all standard character sets—your complete DNC solution that fits in your pocket.
All Machine Link™ features plus six simultaneous communication sessions from a single computer—ideal for shops servicing multiple CNC machine tools concurrently, even during extended drip feeds.
Real-time data collection software combining time and frequency domain analysis for vibration monitoring, process monitoring, and modal testing using NI hardware across your production environment.
Custom process monitoring, system control, and end-of-line testing solutions. Controlink's engineers integrate SQL databases, PLC hardware, motion controllers, and industrial protocols into unified shop systems.
Manufacturing facilities lose significant productive time when operators leave their machines to retrieve CNC programs, consult engineering, or troubleshoot file transfers. Controlink Systems LLC's shop floor time management solutions eliminate that waste. Our software keeps machinists focused on cutting parts—automatically serving the latest engineering-approved files to each machine, reducing scrap caused by outdated programs, and giving engineering real-time visibility into shop-floor changes. Trusted by industry leaders like 3M, Kodak, and Oak Ridge National Laboratory since 1998.
