USED HAAS ST45Y

The Haas ST-45Y is a large CNC turning center designed to combine high-power turning with advanced Y-axis milling capability, allowing shops to machine complex parts more efficiently in a single setup. As part of Haas Automation’s ST Series — one of the most widely adopted CNC lathe lines worldwide — the ST-45Y features a robust mechanical structure with a heavy cast iron base and precision box-way guideways that deliver rigidity and stability even under heavy machining loads. Its extended travel envelopes accommodate larger parts, making it suitable for automotive, aerospace, energy, oil & gas, and heavy engineering applications.

The inclusion of a Y-axis expands the machine’s versatility beyond traditional turning. With Y-axis capability, operators can perform off-center drilling, cross-hole machining, pocket milling, and other milling operations without additional fixtures or secondary setups. This significantly reduces cycle time and handling, improving accuracy and productivity.

The Haas CNC control system equips the ST-45Y with intuitive conversational programming, full G-code support, USB/Ethernet connectivity, and advanced features such as tool offset memory, rigid tapping, and programmable macros. Optional accessories such as live tooling, high-pressure coolant systems, chip conveyors, and probing packages further enhance capability. Whether used for production runs or complex one-off parts, the ST-45Y delivers a balanced blend of power, precision, and flexibility that fits many manufacturing environments.

WHY BUY USED HAAS ST45Y

Purchasing a used Haas ST-45Y can be a highly cost-effective way to add large turning and milling capability to a shop without paying the full price of a brand-new machine. CNC turning centers often depreciate most in their first few years, so well-maintained used machines frequently sell for a significant discount while still offering decades of useful life. The ST-45Y’s combination of turning and Y-axis milling capability allows multi-surface machining in a single setup, reducing cycle time and fixturing costs relative to separate machines.

One of the biggest advantages of choosing a used Haas is the broad global support network. Haas Automation has a vast service and parts infrastructure, ensuring reliable access to replacement components and technical support. Many operators are already familiar with Haas controls, which helps reduce training time and smooth machine integration into existing workflows.

Because the ST-45Y integrates milling features with turning and can be equipped with optional accessories — such as chip conveyors, high-pressure coolant, probing systems, and live tooling — a used machine can be outfitted to meet production needs without excessive additional investment. When paired with automation like bar feeders or robot loaders, a used ST-45Y can support higher throughput and lights-out machining, offering strong value and return on investment for job shops and contract manufacturers alike.

HOW MUCH DOES A USED HAAS ST45Y COST?

The cost of a used Haas ST-45Y varies based on age, spindle hours, included options, general condition, and demand in the local market, but typical price ranges can help buyers plan budgets. Because the ST-45Y offers both Y-axis milling and large turning capability, it usually commands higher used values than simpler fixed-axis models.

Older units with higher hours and minimal added options often sell in the $60,000 to $90,000 USD range. These machines provide solid mechanical capability for large parts and off-center milling, though they may require servicing or updates to match modern production needs.

Used ST-45Y machines that are mid-life — generally under 8–12 years old with moderate hours, chip conveyor, high-pressure coolant, and standard control — typically trade between $90,000 and $140,000 USD. These units are often ready for production use with minimal additional investment and can be excellent value for growing shops.

Late-model, low-hour ST-45Y units equipped with advanced productivity options — such as live tooling, probing systems, bar feeders, or robotic automation — can command $140,000 to $180,000+ USD in competitive markets. Regional demand also affects pricing, with North American and Western European markets often showing higher values due to strong industrial demand. Buyers should also include transport, rigging, installation, and tooling costs when calculating total investment.
