Used Haas machines and equipment

What is Haas?

Haas is the brand of Haas Automation, Inc., an American CNC machine tool builder headquartered in Oxnard, California. Gene Haas founded the company in 1983; its first product was a fully automatic programmable collet indexer, and the first Haas vertical machining centre, the VF-1, followed as a CNC machine aimed at small and mid-sized shops. Today the programme centres on VF-series vertical machining centres, horizontal machining centres, UMC-series 5-axis machines, ST/CL turning centres and rotary tables, all running the Haas CNC control.

Main machine groups on the used market

• Vertical machining centres (VF series) — from compact VF-1/VF-2 class machines upwards in table size and spindle power; among the most frequently traded Haas machines.
• 5-axis machining centres (UMC series) — e.g. the UMC-750 with an integrated high-speed dual-axis trunnion table, usable for both 3+2 positional and simultaneous 5-axis work.
• Turning centres (ST/CL series) — CNC lathes with and without live tooling; bar-fed and chucking configurations.
• Control — all Haas machines use the in-house Haas CNC control. Across model years its hardware and software generation changes (from early controls to current NGC), which drives what networking, probing and programming features a used machine offers.

Buying a used Haas — what to check

• Control generation and options. Record the control software version and installed options (probing, rigid tapping, high-speed machining, bar feeder interface, tool changer size). Options are software-locked and are not automatically present on every machine of a given model.
• Spindle hours and history. Ask for spindle run time and any rebuilds; check spindle noise at full RPM, taper condition and tool holder clamping.
• Wear on axes. Test backlash and backlash compensation values, way lube system function, way cover damage and ballscrew condition on all axes; on 5-axis machines also check trunnion/torque-table backlash and brake holding.
• Tool changer and turret. Cycle the umbrella/side-mount ATC and (on turning centres) the turret fully, including live tooling; verify tool-change alarms under repeat cycles.
• Electrical and cooling. Inspect the cabinet for dust, coolant ingress and burnt contactors; check the spindle chiller (where fitted) and chip/coolant system.
• Run-off and documentation. A test cut with measured part dimensions is the practical check of positioning accuracy; maintenance logs and original documentation help with later service and parts.

FAQ

• What control do Haas machines use? The Haas CNC control, built in-house. The interface is broadly consistent across generations, but hardware and software capabilities (networking, probing, high-speed machining, data transfer) depend on the generation and licence options — check the exact software version on the machine you consider.
• Are Haas spares and service available in Europe? Haas runs its own service and parts operations in Europe — its UK organisation, for example, employs full-time Haas engineers and stocks parts in local warehouses. On older machines, parts availability should still be confirmed per unit, especially for early control electronics.
• VF-2 vs UMC-750 — which fits my parts? The VF-2 is a 3-axis vertical mill suited to prismatic parts machined in one or more setups; the UMC-750 adds simultaneous 5-axis positioning via a trunnion table, which reduces setups for complex or multi-face parts. Match travel, spindle speed and axis configuration to the parts you actually run.
