Used Milltronics Partner 23.5: Sell or Buy at Auction
Milltronics is an American CNC machine tool builder known for the Centurion conversational CNC control system that makes part programming accessible without G-code expertise. Milltronics vertical machining centers and knee mills are a popular choice in job shops, toolrooms, and educational environments throughout North America. Domestic manufacturing and parts support provide strong serviceability.
The Milltronics Partner 23.5 belongs to Milltronics' Partner line of CNC knee mills, a knee-and-column machine that pairs a quill-fed vertical head with Milltronics' Centurion conversational control. The appeal of the Partner platform is that an operator can program it right at the machine using Centurion's conversational prompts, without writing G-code by hand, while keeping the familiar knee mill layout and handwheel feel. Quill-fed Partner knee mills are typically fitted with an R8 spindle, so a shop moving from manual milling to CNC keeps its existing R8 collets and tooling in play. Toolrooms, vocational training programs, and small job shops favor this format because it adds CNC repeatability for prototype and short-run work without giving up the compact footprint or the hands-on feel of a knee mill. When a Partner 23.5 comes up for sale, KD Auctions markets it to 500,000+ industry contacts, and clean, running Centurion-controlled Milltronics knee mills tend to draw active bidding from shops that want straightforward CNC capability without a steep learning curve.
