USED HAAS ST35

The Haas ST-35 is a heavy-duty CNC turning center designed for machining larger diameter parts with high rigidity and strong cutting performance. Built as part of the Haas ST-Series line of CNC lathes, the ST-35 is engineered to handle demanding turning operations across industries such as oil and gas, aerospace, automotive, and heavy equipment manufacturing. With its robust cast-iron construction, powerful spindle motor, and large work envelope, the Haas ST-35 provides the stability and torque required for machining large steel, alloy, and stainless-steel components with consistent accuracy.

The machine features a 12-inch chuck and a large spindle bore with a 4-inch bar capacity, allowing it to handle larger raw materials and bar stock efficiently. Its maximum part swing of approximately 21 inches and cutting length of about 32.5 inches make it suitable for producing large cylindrical components such as shafts, flanges, couplings, and industrial fittings. The 40 hp spindle with a maximum speed of 3,200 RPM delivers strong torque for heavy roughing cuts as well as precision finishing operations.

The Haas ST-35 is typically equipped with a 12-station bolt-on tool (BOT) turret, enabling fast tool indexing and reliable turning performance. The machine is controlled by the intuitive Haas CNC control system, which simplifies programming and allows operators to easily manage tool offsets, machining programs, and diagnostics. Features such as Ethernet connectivity, USB ports, and remote monitoring capabilities help integrate the machine into modern digital manufacturing workflows.

Because of its combination of power, large capacity, and dependable CNC control, the Haas ST-35 is widely used in production shops and heavy machining applications where large turned parts must be produced efficiently and with tight tolerances.

WHY BUY USED HAAS ST35

Purchasing a used Haas ST-35 can provide manufacturers with a powerful CNC turning solution at a significantly lower cost compared to buying a new machine. The ST-35 is known for its robust construction and high-torque spindle, making it well suited for heavy turning applications involving large steel or alloy components. Because the machine has a large chuck size and high bar capacity, it is often used in industries that require machining of larger cylindrical parts such as oilfield connectors, industrial couplings, and pump components.

Another advantage of buying a used Haas ST-35 is the widespread availability of service, spare parts, and trained operators. Haas machines are among the most common CNC machines in the world, making maintenance and support relatively straightforward. Many used machines are also sold with valuable options such as chip conveyors, bar feeders, tailstocks, and upgraded tooling packages, which can increase productivity and reduce setup time. For companies seeking a reliable heavy-duty CNC lathe, a used Haas ST-35 offers strong machining capability and long-term value.

HOW MUCH DOES A USED HAAS ST35 COST?

A used Haas ST-35 typically sells in the range of $65,000 to $140,000 USD, depending on factors such as the year of manufacture, machine condition, operating hours, and included options. Older machines from the early 2000s may be available in the $65,000–$85,000 range, while newer models with upgrades such as live tooling, sub-spindles, chip conveyors, or automation systems may reach $100,000–$140,000 or more. Because of its heavy-duty construction and large turning capacity, the Haas ST-35 remains a popular and valuable machine in the used CNC equipment market.
