USED HAAS VF-4SS – 2018

The HAAS VF-4SS is a high-performance Super-Speed vertical machining center designed for manufacturers requiring high spindle speeds, rapid axis movement, fast tool changes, and efficient production cycles. The 2018 HAAS VF-4SS provides approximately 50″ x 20″ x 25″ of X, Y, and Z-axis travel, making it suitable for medium-to-large components, fixtures, molds, dies, aerospace parts, automotive components, and general industrial manufacturing.

The VF-4SS is built around a 12,000 RPM, 30 HP inline direct-drive spindle and a high-speed side-mount automatic tool changer. Its Super-Speed configuration is designed to reduce cycle times through rapid axis movements and quick tool changes, making the machine particularly effective for high-volume and repetitive production work.

The machine’s 40-taper spindle provides a practical balance between high-speed machining and general-purpose cutting performance. With a 52″ x 19.5″ table and a maximum evenly distributed table load of approximately 1,750 pounds, the VF-4SS can accommodate substantial fixtures and workpieces while maintaining the flexibility of a standard vertical machining center.

Depending on the individual 2018 machine, options may include through-spindle coolant, probing, programmable coolant, chip conveyor or auger, high-speed machining, additional tool capacity, and fourth-axis integration. The 2018 HAAS VF-4SS remains a strong used CNC option for job shops and production manufacturers seeking high-speed machining capability without the cost of purchasing a new machine.

INDUSTRIES THAT USE HAAS VF-4SS

The HAAS VF-4SS is widely used in aerospace, automotive, defense, medical, mold and die, robotics, electronics, and general contract manufacturing. Aerospace manufacturers use the machine for brackets, housings, fixtures, structural components, and other precision parts requiring fast and repeatable machining.

Automotive manufacturers benefit from the machine’s high spindle speed and rapid tool changes when producing repeated components, prototypes, fixtures, brackets, and specialized production parts.

Mold and die manufacturers use the VF-4SS for cavities, cores, electrodes, tooling components, and complex contoured parts. Medical manufacturers can use the machine for precision components, surgical equipment parts, fixtures, and specialized medical devices.

The machine is also well suited for general job shops because its large work envelope allows it to handle larger parts while its Super-Speed configuration supports shorter production cycles.

---

TYPICAL PARTS HAAS VF-4SS CAN PRODUCE

The HAAS VF-4SS can produce a wide range of precision-machined components, including aerospace brackets, automotive parts, industrial housings, mold and die components, fixtures, tooling, medical components, and automation parts.

Its 50-inch X-axis travel allows manufacturers to machine relatively large components, while the 12,000 RPM spindle supports high-speed cutting applications, especially when machining aluminum and other materials that benefit from higher cutting speeds.

Typical applications include production brackets, aluminum components, steel fixtures, complex housings, prototype parts, automation components, mold inserts, and custom-engineered industrial products.

WHY CHOOSE HAAS VF-4SS

The main advantage of the HAAS VF-4SS is its combination of a substantial work envelope and high-speed production performance. The 12,000 RPM inline direct-drive spindle, rapid axis movement, and Super-Speed tool changer are designed to reduce cycle times and improve machine productivity.

The 30 HP spindle provides sufficient power for a broad range of machining operations, while the 40-taper configuration offers a good balance between high-speed machining and general-purpose cutting rigidity. The machine’s 50″ x 20″ x 25″ travels also allow it to handle larger workpieces than many compact high-speed VMCs.

The VF-4SS is highly configurable, with options such as probing, through-spindle coolant, programmable coolant, chip conveyors, expanded tool magazines, high-speed machining, and fourth-axis equipment.

For manufacturers seeking a fast and versatile vertical machining center capable of handling both production work and larger components, the VF-4SS is a strong CNC platform.

WHY BUY USED HAAS VF-4SS

Purchasing a used 2018 HAAS VF-4SS allows manufacturers to acquire a relatively modern Super-Speed vertical machining center at a lower cost than purchasing new equipment with comparable performance.

The machine’s high-speed spindle, rapid axis movement, and fast tool changes can improve productivity in repetitive production applications. The large work envelope also allows the machine to handle a wide range of components without requiring the investment in a larger-format VMC.

A used 2018 VF-4SS may include valuable options such as through-spindle coolant, probing, programmable coolant, chip management, high-speed machining, and expanded tool capacity. These options can significantly increase the machine’s production value.

Because a used machine’s condition can vary considerably, buyers should inspect the spindle, ballscrews, linear guides, axis drives, tool changer, control electronics, machine geometry, and coolant system before purchase. Spindle hours and maintenance history are particularly important when evaluating a high-speed machining center.

HOW MUCH DOES A USED HAAS VF-4SS COST?

A used 2018 HAAS VF-4SS typically sells for approximately $55,000 to $80,000, depending on the machine’s condition, spindle hours, installed options, maintenance history, tooling package, and seller location. A clean, well-maintained machine with valuable production options can command a premium over a basic example.

Machines equipped with through-spindle coolant, probing, programmable coolant, chip conveyor, high-speed machining, expanded tool capacity, and fourth-axis capability will generally have greater market value. The condition of the 12,000 RPM direct-drive spindle is particularly important because spindle repair or replacement can represent a significant expense.

Machines with low operating hours, documented maintenance, good axis geometry, and a clean production history may approach or exceed the upper end of the typical range. Machines requiring spindle work, ballscrew replacement, tool changer repairs, or significant electrical maintenance may sell for less.

For context, Haas’s published pricing for a new VF-4SS in a 2023 quote was $91,695 before options, while additional options could substantially increase the total investment. This provides useful context for why a well-maintained 2018 used machine can remain a valuable asset at a significantly lower price.

In addition to the purchase price, buyers should budget for transportation, rigging, installation, electrical connection, tooling, inspection, and possible preventive maintenance. For manufacturers seeking high-speed production capability with a large machining envelope, a used 2018 HAAS VF-4SS can provide excellent value compared with purchasing a new Super-Speed VMC.
