The 2021 Haas ST-20Y is a Y-axis CNC turning center built around an 8-inch hydraulic chuck, 2-inch bar capacity, a 4,000-RPM main spindle driven by a 30 HP motor, and 17.5 inches of max turning diameter over a 21-inch turning length envelope, with 4 inches of Y-axis travel for off-center milling and drilling that single-turret lathes simply can't reach. Optioned with a 12-station BOT live-tooling turret rated to 4,000 RPM, an integrated bar feeder, parts catcher, automatic tool presetter, tailstock, and the Haas Next Generation Control with conversational programming, macros, M19 spindle orient, rigid tapping, wireless networking, compensation tables, and 1 GB of part program memory enabled, this lathe is configured to run aluminum and stainless production work in a single setup.
Compared to the older Haas SL-20 platform that the ST-20 series replaced, this 2021 build delivers the modern Haas NGC control over the older Haas Classic Control, BOT turret indexing in place of the older block-style toolholders, and the Y-axis package for milled features that the SL-20 simply could not address. With bar feeder, parts catcher, and tool presetter already paid for, this near-new ST-20Y skips the typical option-pack adders of a comparably configured new turning center, making it a meaningful price-to-capability win for shops chasing automated bar-fed production.
