The Best-Value Long Bed CNC Turning Centres in the Industry

Rigid, high-performance CNC lathes with a wide selection of available options for every workshop.

The ST-20L long-bed turning centre further expands the already large range of Haas ST series models. The ST-20L provides roughly double the Z-axis travel and turning length of the standard ST-20 for machining longer parts, while maintaining superior cutting performance, and a compact footprint.

This long-bed lathe is engineered from the ground up to create a rigid and high-performance machine. It offers a wide selection of productivity-enhancing options, and more features and value than ever before.

  • Extended Z-axis travel for machining longer parts
  • Standard programmable hydraulic tailstock with #4 Morse taper
  • New castings for increased rigidity and damping properties
  • Ergonomically designed for everyday operation
  • Extended tool pocket in the bulkhead provides clearance for long tools
  • Available BMT65 12-station turret
  • Available Steady Rest Provision for part-face machining or supporting extra-long parts
  • Made in the USA

Redesigned ST-20/25 series turning centres

Introducing the completely redesigned ST-20/25 series turning centres. The redesigned lathes feature more Z-axis travel; an increased wedge angle for more rigidity and better chip evacuation; and completely new castings for an 11% smaller footprint. The new machines come standard with an auto door, and are available with a dual-stage parts catcher, finishing sub-spindle, and our new Automatic Parts Loader (APL)

The BMT65 Turret and Live Tooling for Haas Lathes

Why move your turned parts to a mill for secondary operations when you can machine them complete on a Haas lathe with the BMT65 Turret and Live Tooling? 

The BMT65 Turret and Live Tooling are standard on Haas Y-Axis lathes (ST-20Y through ST-35Y), and optional on non Y-axis models.
