USED HAAS ST-35 – 2022

The HAAS ST-35 2022 is a heavy-duty CNC Turning Center designed for precision turning, boring, threading, grooving, facing, and high-volume production machining. The ST-35 is a mid-size big-bore CNC lathe that combines a rigid machine structure with a large work envelope, high spindle power, and substantial bar capacity. It is particularly suited for manufacturers that need more turning capacity than smaller Haas ST-series machines while maintaining a relatively compact footprint.

The 2022 HAAS ST-35 provides a maximum part swing of approximately 533 mm (21″), a maximum cutting diameter of approximately 381 mm (15″) with the standard BOT turret, and a maximum cutting length of approximately 826 mm (32.5″). The machine uses a 12-inch hydraulic chuck, 102 mm (4″) bar capacity, A2-8 spindle nose, 3,200 RPM spindle, and 40 HP spindle motor. The spindle bore is approximately 117.3 mm (4.62″).

The machine is commonly equipped with a 12-station bolt-on tool turret, Haas Next Generation Control, 24 m/min X and Z rapid traverse, rigid tapping, 55-gallon coolant tank, Ethernet, Wi-Fi, HaasConnect, and HaasDrop. Depending on configuration, options can include a 12-station BMT65 live-tool turret, 24-station half-index BMT65 turret, chip conveyor, high-pressure coolant, automatic parts catcher, automatic door, and sub-spindle.

The HAAS ST-35 2022 is an excellent choice for manufacturers producing large shafts, hydraulic components, oil and gas parts, automotive components, pump components, valve bodies, flanges, bushings, and other medium-to-large precision turned components.

WHY BUY USED HAAS ST-35 2022

Purchasing a used HAAS ST-35 2022 allows manufacturers to acquire a relatively modern big-bore CNC turning center while reducing the capital investment compared with purchasing a new machine.

Many used machines may include valuable options such as:

• 12″ hydraulic chuck
• 40 HP spindle
• 4″ bar capacity
• 12-station BOT turret
• BMT65 live tooling
• C-axis capability
• High-pressure coolant
• Chip conveyor
• Automatic parts catcher
• Automatic door
• Sub-spindle
• Haas Next Generation Control
• Wi-Fi
• HaasConnect
• HaasDrop
• Advanced Tool Management
• 1 GB program memory

Before purchasing, buyers should inspect the main spindle, spindle bearings, chuck, drawtube, turret indexing, ballscrews, linear guides, CNC control, hydraulic system, coolant system, chip conveyor, lubrication system, electrical cabinet, and overall machine geometry.

Maintenance records, spindle hours, alarm history, tooling, and evidence of previous crashes should also be reviewed.

HOW MUCH DOES A USED HAAS ST-35 2022 COST?

The value of a used HAAS ST-35 2022 depends on spindle hours, machine condition, turret configuration, live tooling, sub-spindle, chuck condition, tooling package, coolant options, chip conveyor, maintenance history, and overall operating condition.

Machines equipped with BMT65 live tooling, C-axis, sub-spindle, high-pressure coolant, automatic parts catcher, chip conveyor, automatic door, extensive tooling, and low spindle hours generally command higher resale values.

For used-equipment listing purposes, a used HAAS ST-35 2022 can typically be expected to sell in the approximately $80,000 to $125,000 USD range, with the actual value depending heavily on condition, hours, configuration, options, tooling, and location.

A low-hour machine with excellent spindle condition, accurate turret operation, complete tooling, live tooling, production automation, and documented maintenance may command a premium. A machine with high production hours or requiring spindle, hydraulic, turret, or control repairs may sell for considerably less.
