ST-20LY

   
 
Y-Axis CNC Lathe with 11.75" x 42.5" max capacity and 2.5" bar capacity

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.

  • 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
  • 8.3" Chuck Size
  • 2.5" Bar Capacity
  • 4k RPM
  • 20 hp Power

*Haas machines are designed to operate on 220 VAC power. 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.
