Overview

The Doosan Puma 2600SY is a CNC turning center from Doosan's flagship Puma series — the best-selling CNC lathe line in Korea and one of the most widely installed turning center families globally. The SY designation indicates the machine has both a Sub-spindle (second spindle) and Y-axis capability on the main turret, making it a twin-spindle, Y-axis turning center capable of complete part machining in a single setup for bar-fed production.

The Puma 2600SY's main spindle handles 10-inch chuck work (65mm bar capacity) with a 15 kW motor at 3,500 RPM for steel, stainless, and aluminum turning. The sub-spindle (second chuck, synchronized) grips completed parts from the main spindle and performs secondary operations (facing, drilling, threading) on the back face — eliminating the manual transfer and refixturing step that conventional single-spindle lathes require. The Y-axis (±50mm stroke) enables off-center milling, drilling, slotting, and threading operations that would otherwise require a separate milling machine or machining center after turning.

For bar-fed production (with an optional automatic bar feeder), the Puma 2600SY machines complete parts from raw bar stock — turning, drilling, milling, threading, and back-face operations — and drops finished parts into a parts catcher for collection. This workflow eliminates work-in-process inventory between lathe and mill operations and reduces total part cost by combining multiple setups into one.

At $200,000-$300,000 (depending on bar feeder and options), the Puma 2600SY is competitively priced in the sub-spindle Y-axis turning center segment against Mazak Quick Turn Nexus 250-II MSY, Okuma LB3000EX MYLL, and Haas ST-20Y. Doosan's value positioning and strong North American dealer network (Methods Machine Tools carries Doosan prominently) make the Puma series highly competitive in this market.

Strengths & Limitations

Strengths

Sub-spindle transfers parts from main to sub for complete front-and-back machining in a single bar-fed cycle
Y-axis enables off-center milling, drilling, and slotting without a separate machining center operation
Bar feeder ready — with a bar feeder, produces complete finished parts lights-out from raw bar stock
12-station turret with live tooling provides sufficient tool capacity for complex turned-milled parts
Puma series is Doosan's flagship — broad installed base ensures parts availability and service familiarity
Competitive pricing in the SY turning center segment — typically below Mazak and Okuma equivalents

Limitations

±50mm Y-axis stroke limits off-center milling depth — complex milling operations requiring more Y travel need a machining center
4,000 RPM live tooling speed is adequate but not high-speed milling — complex milling features are better done on a VMC
Sub-spindle power (7.5 kW) limits heavy back-face cutting operations
Doosan's service network, while growing, is less dense than Mazak's or Haas's in some North American regions

Best For

Bar-fed production shops producing complete turned-milled parts — automotive fasteners, fittings, valves, and connectors with off-center features Job shops seeking to consolidate lathe + mill operations into a single-machine workflow for medium-to-high volume parts Shops machining hydraulic fittings, pneumatic valves, and plumbing components requiring turning + cross-drilling + threading in one setup Aerospace and medical parts manufacturers producing complex rotationally symmetric parts requiring multiple machining operations High-mix shops reducing WIP and lead time by combining turning and milling operations on single SY platform

Frequently Asked Questions

01 What does SY mean on a Doosan turning center?

SY stands for Sub-spindle + Y-axis. The S designates a sub-spindle (second spindle) that can grip the workpiece from the main spindle and machine the back face. The Y designates a Y-axis on the main turret, enabling off-center milling, drilling, and slotting perpendicular to the spindle centerline. Together, SY capability allows complete front, back, and milled-feature machining in a single setup.

02 Can the Puma 2600SY run bar stock automatically?

Yes, with an optional automatic bar feeder (typically a 12-foot or 6-foot bar feeder from Iemca, LNS, or Haas's own feeder). The bar feeder pushes bar stock through the spindle chuck as each part is completed. Combined with the sub-spindle parts catcher, the machine produces complete finished parts in unattended bar-fed mode. Most shops running the 2600SY pair it with a bar feeder for overnight unmanned production.

03 How does the Puma 2600SY compare to the Haas ST-20Y?

Both are sub-spindle Y-axis turning centers in the 65mm bar class. The Haas ST-20Y benefits from Haas's nationwide HFO service network and strong parts availability. The Doosan Puma 2600SY typically offers comparable specifications with a slight pricing advantage and Fanuc control versus Haas's proprietary control. Shops prioritizing Haas service convenience or Haas control familiarity will favor the ST-20Y; shops comfortable with Fanuc or Siemens controls and seeking value should compare the Puma 2600SY carefully.

04 What part families is the Puma 2600SY best suited for?

The Puma 2600SY excels at parts requiring combination turning and milling: hydraulic fittings with cross-drilled ports, valve bodies with off-center features, automotive fuel system components, medical implant shafts with machined features, and aerospace fasteners and standoffs with milled hex or flat features. The sub-spindle makes it ideal for any part requiring back-face operations that would otherwise need manual transfer.
