Automation Options

The ST-20LY is a long-bed turning center with Y-axis and C-axis capabilities, allowing high-productivity, done-in-one machining operations. The ST-20LY provides roughly double the Z-axis travel and turning length of the standard ST-20Y for machining longer parts, while maintaining superior cutting performance, and a compact footprint. The ST-20LY is engineered from the ground up to create a rigid and high-performance machine. A wide selection of productivity-enhancing options and powerful standard features provides more value than ever before.

  • 12-station BMT65 turret
  • Y-axis milling, drilling, and tapping
  • Extended Z-axis travel for machining longer parts
  • Standard programmable hydraulic tailstock with #4 Morse taper
  • Extended tool pocket in the bulkhead provides clearance for long tools
  • Available Steady Rest Provision for part-face machining or supporting extra-long parts
  • Made in the USA

An optional internal high-voltage transformer (380 - 480 VAC) is available for all models, except the Desktop Mill, CL-1, and CM-1. This optional high-voltage internal transformer is not field installable; it must be ordered with the machine.

ATTENTION! Optional high-performance spindles have a higher power requirement than the standard spindle. Verify the power requirement before running power for your machine.

LATHE Drilling: EVERYTHING YOU NEED TO KNOW
Mark shows you everything you need to know to drill on a Haas lathe. Whether you have a standard 2-axis lathe, a dual-spindle lathe, or even a live-tool lathe, Mark simplifies the process, and explains all the G and M codes you’ll ever need.
CUT CYCLE TIMES AND POSITION YOUR TURRET USING G53
Mark demonstrates how using a G53 command instead of G28 not only saves valuable cycle time, but also reduces the risk of crashing your machine. Mark walks you through both G-codes, and explains how and when to use each one.
THE HAAS BMT65 TURRET
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 system provides increased cutting performance, longer tool life, and better tool clearance.
Setting Up Live Tools
Properly setting up live tools on a turning center can be tricky. Mark guides you through the process with a step-by-step tutorial that will answer all your questions.
