Overview

The Haas DS-25Y steps up from the DS-20Y with a 254 mm (10 in) main chuck, 76 mm (3.0 in) bar capacity, and a 22.4 kW (30 hp) main spindle. It is the mid-range dual-spindle Y-axis turning center in the Haas lineup, built on the same redesigned platform as the ST-25Y but adding a sub-spindle for back-working capability.

The main spindle delivers 407 Nm (300 ft-lb) of torque at 500 RPM with a max speed of 3,400 RPM on an A2-6 nose. The sub-spindle runs 11.2 kW (15 hp) at up to 4,000 RPM with a 203 mm (8 in) chuck on an A2-5 nose. Both spindles support C-axis positioning at plus or minus 0.01 degrees, giving you full mill-turn capability on front and back operations.

Y-axis travel is 102 mm (4.0 in) total on the 12-station BMT-65 turret with 6,000 RPM live tooling at 3.7 kW (5 hp). The BMT-65 turret provides solid clamping rigidity for milling operations. The turret indexes to serve both main and sub-spindle, so your entire turning, milling, cutoff, and back-working cycle runs as a single program.

Max cutting diameter is 349 mm (13.75 in) with a cutting length of 584 mm (23 in). The 76 mm bar capacity covers the most common production bar stock sizes, a meaningful step up from the DS-20Y's 63.5 mm. For production bar feeding operations, that extra half-inch of bar capacity opens up a wider range of part sizes.

At roughly $145,000-$180,000 configured, the DS-25Y bridges the gap between the smaller DS-20Y and the top-of-range DS-30Y. The 30 hp main spindle provides 50% more power than the DS-20Y, which shows up when roughing steel and stainless at production feed rates. Shops running parts in the 50-75 mm bar stock range with features on both ends will find the DS-25Y hits the sweet spot between capability, bar capacity, and price.

Strengths & Limitations

Strengths

  • 30 hp main spindle with 300 ft-lb of torque provides 50% more roughing power than the DS-20Y for production in steel and stainless
  • 76 mm (3.0 in) bar capacity covers the most common production stock sizes, a meaningful upgrade from the DS-20Y's 2.5 inches
  • Dual-spindle with Y-axis and C-axis on both spindles enables complete done-in-one production without second operations
  • 10-inch main chuck and 8-inch sub-spindle chuck provide secure clamping across a wide range of part diameters
  • BMT-65 turret with 6,000 RPM live tooling delivers real milling capability on both front and back operations
  • Same NGC control as every Haas machine, with dual-spindle synchronization handled through standard G-code

Limitations

  • 3,400 RPM main spindle speed is lower than the DS-20Y's 4,000 RPM, limiting surface speed on small-diameter work
  • 3.7 kW (5 hp) live tooling motor is the same as the smaller DS-20Y and can feel underpowered for aggressive milling
  • Programming dual-spindle with Y-axis operations requires experienced CAM programmers and proper post-processors
  • No optional gearbox on the DS-25Y limits low-speed torque for heavy interrupted cuts on large diameters
  • Higher price than single-spindle ST-25Y means longer payback period on lower-volume production

Frequently Asked Questions

01 What does a new Haas DS-25Y cost?

Base price starts around $145,000. With common options including chip conveyor, high-pressure coolant, parts catcher, and bar feeder interface, configured price runs $160,000-$180,000. The sub-spindle is included in the base configuration.

02 What is the difference between the DS-25Y and the DS-20Y?

The DS-25Y bumps the main spindle to 30 hp (from 20 hp), the main chuck to 10 inches (from 8 inches), and bar capacity to 3.0 inches (from 2.5 inches). The sub-spindle upgrades from a 6.5-inch to an 8-inch chuck. Expect about $15,000-$20,000 more than the DS-20Y.

03 How does the DS-25Y compare to the ST-25Y?

Same platform, same main spindle specs. The DS-25Y adds a sub-spindle for back-working. If your parts need machining on both ends, the DS-25Y eliminates the second operation. If all your features are on the front, the ST-25Y saves $40,000-$50,000.

04 Can I run the DS-25Y without using the sub-spindle?

Yes. The sub-spindle retracts out of the way and the machine operates as a standard Y-axis turning center for parts that only need front-side machining. You get full ST-25Y capability plus the option to engage the sub-spindle when needed.

05 What CAM software supports dual-spindle programming?

Mastercam, Esprit, GibbsCAM, and Inventor HSM Ultimate all support dual-spindle mill-turn programming for Haas DS machines. You will need a proper post-processor configured for the DS platform. Some shops program simpler dual-spindle cycles directly in G-code.
