Y-Axis CNC Lathe with 27.5" x 80" max capacity and 7.0" bore

The ST-45LY adds Y-axis motion to our long-bed, large-bore ST-45 to create a large-frame turning center with a generous work envelope and secondary milling capabilities. The addition of Y-axis motion, C-axis interpolation, and live tooling allows milling, drilling, and tapping for increased machine capabilities. This machine offers an excellent combination of performance, capacity, and value.

  • Extra-long work envelope
  • Fully programmable servo tailstock
  • 12-station base mount turret (BMT75)
  • A2-11 spindle nose with 7.0" (178 mm) bore
  • Y-axis milling, drilling, and tapping
  • ± 3.0" (76 mm) Y-axis travel
  • Fully interpolated C-axis
  • 18" (opt) Chuck Size
  • 7.0" Bar Capacity
  • 1.4k RPM
  • 40 hp Power

NOTE: All specifications listed are for the standard machine configuration. Optional equipment may change the machine’s specifications.

*Haas machines are designed to operate on 220 VAC (200-240 VAC) power. An optional internal high-voltage transformer (380 - 480 VAC) is available for all models, except the Desktop Machines, CL-1, CM-1, and SR Series routers. This optional high-voltage internal transformer is not field installable; it must be ordered with the machine.

Haas machines destined for Europe and the UK are configured with an internal high-voltage non-isolated transformer to operate on 400 VAC, except the Desktop Machines, CL-1, CM-1, and SR Series routers. 

**Optional tool changers may have a different max tool size than the standard tool changer. Extra-large tools may require two adjacent pockets empty between tools. Click here for toolholder specifications.

ATTENTION! Optional high-performance spindles may have a higher power requirement than the standard spindle. However, if the spindle horsepower (kW) does not change, the power requirement remains the same. Verify the power requirement before running power for your machine.

† Air consumption on 40-taper DC Series machines may be higher, when Through-Tool Air Blast (TAB) is activated.
