Success Stories

Discover how leading manufacturers rely on our HMI solutions to drive efficiency and reduce downtime.

"Machine Link™ is easy to use, was easy to setup, and worked the first time with no problems and I don't even know how to operate Windows. It is far superior to any other communication software I have ever tried. I love it!"

Ken Havard

"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."

Royce Burton

"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™ is great! It's reliable and very easy to use. We manufacture high precision molds and use Machine Link™ to download very large files. We have never had a problem with it."

Chris Wiesmann

"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."
