“The SL-II Series machines are the newest additions to our reinvented product line,” said Louie Pavlakos, Milltronics USA general manager. “In the last two years, we’ve introduced several new lines of tool room machines and vertical machining centers. Now, we’ve brought that same level of quality, accuracy, and reliability to the Milltronics lathe product line. We’ve designed these machines to be tough and powerful but also affordable and easy-to-use. They all feature the new Series 9000 control, which has all the user-friendly features Milltronics is known for, but with upgraded hardware and a new Windows operating system.”
The Series 9000 control runs on an Intel Dual Core i5 64 bit processor and offers 4 GB memory, 120 GB disk storage, 2 USB ports, and an enlarged 15-inch LCD color touch screen. An optional feature for the Series 9000 is Milltronics Shop View (MSV), which allows users to access machine status and collect usage and diagnostic info per Industry 4.0. MSV is hosted in the cloud and can be accessed with a PC, tablet, or smartphone.
“The new SL-II Series are easy to program so anyone in the shop can run them,” Pavlakos said. “They’re perfect machines for small to medium lot sizes or jobs customers have to get out the door in a hurry.”
