Overview

The Haas DS-20Y is a dual-spindle Y-axis lathe sized for 2.5 in (64 mm) bar: an 8.3 in (210 mm) main chuck on a 20 hp (14.9 kW), 4,000 rpm spindle, a 6.5 in (165 mm) sub-spindle chuck, a 12-station BMT65 turret with live tools and ±2 in (±51 mm) of Y travel. Its job is to finish both ends of a part in one cycle.

The two spindles are not twins. The main spindle makes 150 ft-lbf (203 N·m) at 500 rpm on an A2-6 nose with a 3.5 in (88.9 mm) bore. The sub-spindle is rated 15 hp (11.2 kW) and 100 ft-lbf (135.6 N·m) at 870 rpm on an A2-5 nose. It runs to 5,000 rpm, though synchronised running with the main spindle is limited to 4,000 rpm. Plan the heavy roughing for the first operation and leave the second side for lighter cuts.

How far a part can enter the sub-spindle matters for shaft work. The chuck throat is Ø 1.81 in × 1.63 in deep (Ø 46 mm × 41.4 mm), the drawbar adapter bore is Ø 1.81 in × 4.25 in deep (Ø 46 mm × 108 mm) and the drawbar bore is Ø 1.03 in × 5 in deep (Ø 26.2 mm × 127 mm). The sub-spindle bore itself is 2.31 in (58.7 mm). A slender part can be swallowed some way; a part made from 2.5 in bar cannot go far past the jaws.

Milling capability comes from 4,000 rpm live tools driven 1:1, a main C axis that interpolates and positions to 0.01° with a 250 ft-lbf (339 N·m) brake, and Y thrust of 2,300 lbf (10,231 N). The table also carries two sets of sub-spindle rows: a C axis at 0.01° with a 140 ft-lbf (190 N·m) brake, and a positioning-only arrangement at 0.02°. Confirm with Haas which of the two a quoted machine has.

Turning capacity is 11.75 in (298 mm) in diameter and 22.5 in (572 mm) in length. The machine ships at 11,240 lb (5,098 kg) and runs on 220 VAC at 40 A or 440 VAC at 20 A, three-phase. Haas lists a starting price of US$163,995.

Sub-spindle runs to 5,000 rpm and synchronises with the main spindle up to 4,000 rpm
Y axis of ±2 in (±51 mm) with 4,000 rpm live tools and a C axis positioning to 0.01°
3.5 in (88.9 mm) main spindle bore with 2.5 in (64 mm) bar capacity
Z rapid of 945 ipm (24 m/min)
Runs on 220 VAC at 40 A or 440 VAC at 20 A, three-phase

Limitations

Main spindle torque is 150 ft-lbf (203 N·m) at 500 rpm; the DS-25Y lists 300 ft-lbf (407 N·m) at 500 rpm
Bar capacity is 2.5 in (64 mm), against 3 in (76 mm) on the DS-25Y
Sub-spindle is rated 15 hp (11.2 kW) and 100 ft-lbf (135.6 N·m), less than the main spindle
Sub-spindle chuck throat is Ø 1.81 in × 1.63 in deep (Ø 46 mm × 41.4 mm), which limits how far larger parts enter
Y travel of ±2 in (±51 mm) covers a narrow band on an 11.75 in (298 mm) turning diameter

Best For

Bar-fed parts up to 2.5 in (64 mm) finished on both ends in one cycle Turned parts with cross holes, flats and keyways cut with the Y axis and live tools Chucked work up to 11.75 in (298 mm) in diameter and 22.5 in (572 mm) long Fittings, short shafts and connectors that need second-side work

Frequently Asked Questions

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

Chuck, bar and spindle. The DS-20Y has an 8.3 in (210 mm) chuck, 2.5 in (64 mm) bar capacity and a 20 hp (14.9 kW) spindle with 150 ft-lbf (203 N·m) at 500 rpm and 4,000 rpm. The DS-25Y has a 10 in (254 mm) chuck, 3 in (76 mm) bar capacity and 30 hp (22.4 kW) with 300 ft-lbf (407 N·m) at 500 rpm, at 3,400 rpm. Travels, the 11.75 in (298 mm) turning diameter, the 22.5 in (572 mm) turning length and the 3.5 in (88.9 mm) bore are the same, and the DS-25Y weighs 12,700 lb (5,761 kg) against 11,240 lb (5,098 kg).

02 What are the sub-spindle figures on the DS-20Y?

A 6.5 in (165 mm) chuck on an A2-5 nose, belt driven, rated 15 hp (11.2 kW) and 100 ft-lbf (135.6 N·m) at 870 rpm. Maximum speed is 5,000 rpm, or 4,000 rpm when synchronised with the main spindle. The spindle bore is 2.31 in (58.7 mm), the chuck throat is Ø 1.81 in × 1.63 in deep (Ø 46 mm × 41.4 mm) and the drawbar bore is Ø 1.03 in × 5 in deep (Ø 26.2 mm × 127 mm).

03 How much milling can the DS-20Y do?

The 12-station turret takes BMT65 live tools at up to 4,000 rpm on a 1:1 drive ratio. Y travel is ±2 in (±51 mm) with 2,300 lbf (10,231 N) of thrust. The main C axis runs at up to 60 rpm with a 5 hp (3.7 kW) maximum rating, positions to 0.01° and has a 250 ft-lbf (339 N·m) brake on a 13.9 in (353 mm) disc. That covers cross drilling, flats, keyways and light contouring, not heavy milling.

04 How large a part can the DS-20Y turn?

Maximum turning diameter is 11.75 in (298 mm) and maximum turning length is 22.5 in (572 mm), with a 21 in (533 mm) swing and 8.4 in (213 mm) of X travel. For longer or larger work the DS-30Y lists 13.75 in (349 mm) by 32.5 in (826 mm) with a 10 in (254 mm) chuck and 3 in (76 mm) bar capacity.

05 What power, air and coolant does the DS-20Y need?

Electrical supply is 220 VAC three-phase at 40 A or 440 VAC three-phase at 20 A. Air consumption is 4 scfm at 100 psi (113 L/min at 6.9 bar), with a minimum supply pressure of 80 psi (5.5 bar) through a 3/8 in hose and coupler. The coolant tank holds 55 gal (208 L).
