The Haas ST-45L is a large-format CNC turning center engineered for heavy-duty turning of long parts and demanding production applications. As part of Haas Automation’s ST Series, the “L” designation signifies an extended Z-axis travel, making this machine ideal for machining elongated workpieces such as long shafts, spindles, drive axles, and other linear components without requiring secondary fixtures or additional setups. Built on a rigid cast iron base with precision box-way guideways, the ST-45L provides outstanding structural stability and resistance to vibration, even under heavy material removal conditions.
The machine’s work envelope accommodates substantial part diameters and extended lengths, offering shops the flexibility to handle jobs that might otherwise require multiple machines. The ST-45L is well suited for industries such as automotive, aerospace, oil & gas, energy, and heavy equipment manufacturing. Its high-torque spindle and powerful servo drives ensure consistent performance and surface finish across a range of materials — from aluminum and mild steel to stainless and exotic alloys.
Haas CNC controls combine user-friendly conversational programming with full G-code functionality, USB/Ethernet connectivity, and advanced features like rigid tapping, customizable macros, and coordinate systems. Optional accessories — such as chip conveyors, high-pressure coolant, probing systems, and automation interfaces — can further elevate production efficiency. Whether operated in standalone mode or integrated into automated cells, the ST-45L delivers the power, accuracy, and reliability required for large-part turning operations.

WHY BUY USED HAAS ST45L
Purchasing a used Haas ST-45L can be an excellent investment for shops seeking large-format turning capability without the financial impact of buying new equipment. Like most CNC machine tools, the ST-45L experiences the most rapid depreciation in the first several years of ownership. As a result, a well-maintained used unit can often be acquired at a significantly lower price while still offering many years of productive service. The ST-45L’s robust mechanical architecture — including a heavy cast base, precision box ways, and high-torque spindle — ensures that the core machine structure and motion systems remain capable even after extensive use.
Another major advantage of choosing a used ST-45L is the broad support ecosystem Haas offers. Haas Automation is one of the most widely adopted CNC brands worldwide, with excellent availability of spare parts, tooling, and service support. Many machine operators already have familiarity with Haas controls, which reduces training time and accelerates machine integration into production.
For job shops, contract manufacturers, and production facilities facing larger turning jobs, a used ST-45L provides a cost-effective way to expand capacity. Its extended travel and torque allow for deep cuts and long spans while optional automation — such as bar feeders, robotic loading, and probing systems — can be added to improve throughput, reduce cycle times, and support lights-out machining. A used ST-45L often delivers strong return on investment by combining power, flexibility, and affordability.
HOW MUCH DOES A USED HAAS ST45LCOST?
The price of a used Haas ST-45L varies based on machine age, hours of use, condition, included options, and local market demand. Because the ST-45L is a larger, extended-travel turning center, its used pricing typically sits above smaller counterparts like the ST-35 and ST-40. Older units with higher spindle hours and basic configurations can often be found in the $50,000 to $90,000 USD range. These machines may require some servicing or upgrades but still offer substantial turning capacity and can be strong value buys for shops willing to invest in tooling or refurbishment.
Mid-range used ST-45L machines — generally under 10–12 years old, with moderate usage and additional options such as chip conveyors, high-pressure coolant, or upgraded Haas CNC controls — typically range from $90,000 to $140,000 USD. These units often represent excellent production-ready choices with minimal required upgrades.
Low-hour, late-model ST-45L machines equipped with advanced features — such as live tooling, probing packages, automation interfaces, and bar feeders — can command $140,000 to $180,000+ USD, especially in markets with strong demand and limited supply. Regional variations also influence pricing: North America and Western Europe tend to maintain higher used values compared with other regions. Buyers should factor in transport, rigging, installation, and tooling costs when budgeting total investment to truly understand the machine’s value.
