USED HAAS ST28 – 2024

The 2024 HAAS ST28 is a powerful CNC turning center designed for manufacturers that require heavy-duty cutting performance, larger bar capacity, and modern production efficiency in a compact machine footprint. As part of Haas Automation’s advanced ST-Series lineup, the ST28 combines the strength and torque of a larger production lathe with the floor-space efficiency of a mid-sized turning center, making it highly attractive for both high-volume manufacturing and precision machining operations.

The HAAS ST28 was engineered specifically for shops machining larger diameter materials and demanding industrial components. The machine features a rigid slant-bed design that improves structural stability during aggressive cutting operations while enhancing chip evacuation and reducing vibration. This allows operators to maintain excellent surface finishes, tighter dimensional tolerances, and improved tool life even during continuous production machining cycles.

One of the key advantages of the 2024 ST28 is its large spindle bore and increased bar capacity. Equipped with a heavy-duty A2-8 spindle nose and 12-inch chuck configuration, the machine is capable of machining larger workpieces while delivering high spindle torque for difficult materials and heavy roughing applications. The ST28 is commonly used for turning, threading, boring, facing, grooving, contouring, and drilling operations across a wide range of industrial applications.

The machine is widely used in industries such as aerospace, oil and gas, automotive, heavy equipment manufacturing, hydraulics, energy, defense, and general industrial production. Typical parts produced on the ST28 include valve bodies, hydraulic cylinders, shafts, couplings, threaded connectors, bushings, manifolds, aerospace adapters, and large rotational precision components.

The 2024 HAAS ST28 also benefits from the latest Haas Next Generation Control system, which provides high-speed processing capability, touchscreen functionality, expanded memory, Ethernet and WiFi connectivity, remote monitoring support, and simplified conversational programming. The intuitive control platform helps reduce setup time and improve overall machine productivity in both prototype and production machining environments.

Because of its combination of high-torque spindle performance, compact floor footprint, large bar capacity, and modern CNC technology, the used 2024 HAAS ST28 remains one of the most desirable heavy-duty CNC turning centers in today’s used machinery market.

WHY CHOOSE HAAS ST28

WHY BUY USED HAAS ST28

Purchasing a used 2024 HAAS ST28 is an excellent option for manufacturers seeking modern heavy-duty CNC turning capability without the significantly higher investment associated with new equipment purchases. One of the biggest advantages of the ST28 is its combination of powerful spindle performance and compact machine footprint. The machine delivers the cutting capability of a larger production lathe while occupying less valuable floor space, making it highly attractive for production shops and contract manufacturers.

The ST28 features a large spindle bore and 4-inch bar capacity, allowing manufacturers to efficiently process larger diameter materials without requiring oversized CNC equipment. This capability is especially beneficial for industries such as oil and gas, aerospace, automotive, hydraulics, and industrial manufacturing where larger rotational components are commonly machined.

Another major reason manufacturers continue to purchase used HAAS ST28 machines is the reliability and ease of operation provided by the Haas Next Generation Control system. The control platform includes touchscreen functionality, faster processor speeds, expanded memory, WiFi connectivity, remote monitoring capability, and simplified conversational programming. Haas controls remain widely recognized throughout the machining industry for their intuitive interface and reduced operator learning curve.

The machine’s rigid slant-bed construction helps minimize vibration during aggressive roughing and finishing operations, improving dimensional consistency and extending cutting tool life. This allows shops to maintain high production efficiency while machining materials such as stainless steel, alloy steel, titanium, aluminum, brass, and engineered alloys.

Many used ST28 machines additionally include productivity-enhancing features such as chip conveyors, programmable tailstocks, bar feeders, parts catchers, automatic doors, and high-pressure coolant systems. These options further improve automation capability and support continuous production machining environments.

Another important advantage of purchasing a used HAAS ST28 is the broad availability of replacement parts, tooling systems, service technicians, and aftermarket support throughout the CNC industry. Haas machines remain highly supported worldwide, helping manufacturers reduce downtime and maintain long-term operational reliability.

For manufacturers seeking a modern big-bore CNC turning center with strong spindle performance, large material capacity, and lower ownership costs, the used 2024 HAAS ST28 continues to provide outstanding long-term value.

HOW MUCH DOES A USED HAAS ST28 COST?

The cost of a used 2024 HAAS ST28 depends on several important factors including spindle hours, machine condition, tooling packages, installed options, automation systems, and maintenance history. Since the ST28 is a newer-generation heavy-duty turning center with large bar capacity and advanced control technology, it generally maintains strong resale demand and stable pricing within the used CNC machinery market.

Machines in excellent condition with lower spindle hours typically command premium resale pricing. Machines equipped with valuable production features such as chip conveyors, bar feeders, programmable tailstocks, live tooling packages, automatic doors, high-pressure coolant systems, and automation-ready configurations often sell at higher values because they improve machining efficiency and production flexibility.

Machine condition remains one of the most important pricing considerations. Buyers commonly inspect spindle performance, axis backlash, turret indexing accuracy, lubrication systems, coolant systems, hydraulic systems, and overall machine geometry before purchasing a used CNC turning center. Machines with complete maintenance records and preventative service history generally maintain stronger market value because they may require fewer repairs or refurbishment costs after installation.

The strong industry reputation of Haas Automation also contributes to the resale value of the ST28. Haas machines are widely recognized for dependable machining performance, operator-friendly controls, and strong aftermarket support availability. Many manufacturers specifically seek Haas equipment because machinists are already familiar with the Haas programming environment, reducing setup time and training costs.

A used 2024 HAAS ST28 commonly sells within an estimated range of approximately $110,000 to $220,000 depending on condition, spindle hours, tooling packages, automation systems, and installed accessories. Exceptionally clean machines with advanced automation packages, premium tooling, or low operating hours may exceed this range, while machines requiring repairs or refurbishment may sell below average market pricing.

Additional ownership costs such as transportation, rigging, installation, electrical setup, tooling purchases, coolant systems, and preventative maintenance should also be considered when calculating total investment costs. Even with these added expenses, many manufacturers find that purchasing a used HAAS ST28 provides exceptional long-term value by delivering modern heavy-duty CNC turning capability at a substantially lower investment compared to purchasing comparable new equipment.
