USED HAAS ST40L

The Haas ST-40L is a large-frame CNC turning center designed to handle long-length turning and heavy cutting applications while maintaining precision and rigidity. As part of Haas Automation’s ST Series, the “L” suffix denotes extended Z-axis travel, making this machine especially well-suited for machining long shafts, tubes, spindles, and other elongated components that would otherwise require multiple setups or secondary operations on other machines. The rugged construction — including a substantial cast iron base and precision box-way guideways — ensures long-term durability and vibration damping, even under heavy metal removal.

The ST-40L is commonly used in industries such as automotive, energy, aerospace, oil & gas, power generation, and heavy machinery manufacturing. Its larger work envelope allows shops to take on larger parts while still benefiting from the intuitive and widely supported Haas CNC control system. The Haas interface combines conversational programming, G-code support, and flexible operating modes that experienced CNC programmers and operators find easy to use.

Optional features, such as live tooling, high-pressure coolant, probing systems, and automation integration, make the ST-40L a versatile solution for turning, drilling, grooving, threading, and milling tasks within the same setup. Whether performing high-volume production or complex one-off jobs, the ST-40L delivers a balance of power, precision, and reliability required for modern manufacturing.

WHY BUY USED HAAS ST40L

Buying a used Haas ST-40L offers a compelling combination of value and capability for manufacturers seeking to expand their turning capacity without the cost of a new machine. Large CNC lathes depreciate most in their first few years, meaning that a lightly to moderately used ST-40L can often be acquired at a significantly lower cost while still delivering robust performance. The large envelope and extended travel of the ST-40L make it particularly attractive for shops that need to machine long parts, such as shafts and spindles, without requiring secondary fixtures or setups.

The ST-40L’s durability is well-proven in production environments where rigidity, thermal stability, and consistency are critical. Because Haas is one of the most widely adopted CNC brands worldwide, used machines retain good parts availability, aftermarket support, and a large user community. Operators familiar with Haas controls can typically transition onto a used unit quickly, reducing training time and ramp-up cost.

A used ST-40L can also be paired with automation systems such as bar feeders, parts catchers, or robotic loaders to support lights-out machining and higher throughput. For job shops and contract manufacturers, this machine expands capability into long-part turning while preserving capital for tooling, fixturing, and automation investments that further boost productivity.

HOW MUCH DOES A USED HAAS ST40L COST?

The cost of a used Haas ST-40L varies widely based on factors such as model year, spindle hours, options, condition, and geographic market. Because the ST-40L is a larger, more capable machine than standard medium-sized lathes, its used pricing tends to be higher than smaller models.

On the lower end, older units with higher hours and fewer options can be found in the $50,000 to $90,000 USD range. These machines might include basic turning functionality with extended Z-axis travel but lack live tooling, probing packages, or automation accessories. They may be ideal for shops willing to perform routine refurbishment or add features over time.

Mid-range used ST-40L machines — typically less than 10–12 years old with moderate hours and useful options like high-pressure coolant, chip conveyors, or Haas Next Gen controls — commonly list between $90,000 and $140,000 USD. These are often suitable for production use without further major investment.

Low-hour, late-model units with extensive option packages such as live tooling, robotic integration, and advanced probing can command $140,000 to $180,000+ USD, especially in markets with strong demand. Importantly, regional price fluctuations occur: North America and Western Europe usually maintain higher prices due to stronger demand and lower supply, while prices can be lower in other regions.

When evaluating any used ST-40L, consider mechanical condition, service history, and included tooling/fixtures alongside the quoted price to determine overall value.
