USED DOOSAN PUMA 3100LY

The DOOSAN PUMA 3100LY is a heavy-duty CNC turning center designed for manufacturers that need both high-capacity turning and multi-axis machining capabilities. The machine combines a powerful main spindle with Y-axis movement, C-axis indexing, and live tooling, allowing users to perform turning, milling, drilling, tapping, and other secondary machining operations in a single setup. This makes the PUMA 3100LY particularly valuable for complex components that would otherwise require multiple machines or setups.

The PUMA 3100LY belongs to the PUMA series, a family of high-performance CNC lathes designed for heavy and intermittent cutting, accurate production, and high-quality surface finishes. Its box-guideway construction provides rigidity and vibration resistance during demanding machining operations.

Typical PUMA 3100LY configurations include a 12-inch chuck, approximately 4-inch bar capacity, 16.5-inch maximum turning diameter, 50-inch-class turning length, 11.5-inch X-axis travel, 5.1-inch Y-axis travel, and approximately 53-inch Z-axis travel. A common configuration uses a 2,800 RPM, 30 HP main spindle, 12-station BMT65 turret, and 5,000 RPM live tooling.

The Y-axis and live tooling capabilities are particularly useful for machining complex parts with cross-holes, slots, flats, keyways, and milling features without transferring the workpiece to another machine.

INDUSTRIES THAT USE DOOSAN PUMA 3100LY

The DOOSAN PUMA 3100LY is suitable for demanding manufacturing environments including automotive, aerospace, defense, oil and gas, energy, heavy equipment, industrial machinery, hydraulics, transportation, and general contract machining.

Its combination of Y-axis movement and live tooling makes it particularly valuable in industries where components require both turning and milling operations.

Instead of transferring a turned component to a separate vertical or horizontal machining center for cross-holes, slots, flats, or other milled features, the 3100LY can complete many of these operations directly on the lathe.

---

TYPICAL PARTS DOOSAN PUMA 3100LY CAN PRODUCE

The PUMA 3100LY can produce:

• Hydraulic components
• Shafts
• Flanges
• Couplings
• Bushings
• Valve bodies
• Oil and gas components
• Automotive components
• Aerospace components
• Pump components
• Industrial fittings
• Rollers
• Machine components
• Complex turned and milled parts

Typical operations include turning, facing, boring, threading, grooving, drilling, tapping, cross-drilling, milling, slotting, keyway machining, contouring, and C-axis milling.

---

WHY CHOOSE DOOSAN PUMA 3100LY

The main reason to choose the DOOSAN PUMA 3100LY is its ability to combine heavy-duty turning with multi-axis machining.

The Y-axis provides approximately 5.1 inches of travel, allowing the live tools to move off the centerline for milling and drilling operations. Full C-axis capability allows the workpiece to be accurately indexed for features around its circumference.

The machine also provides a large 12-inch chuck, approximately 4-inch bar capacity, 2,800 RPM spindle, and 30 HP main motor, making it suitable for substantial industrial components.

Its box-guideway construction provides the rigidity needed for demanding cutting operations, while the BMT65 turret and 5,000 RPM live tooling provide substantial secondary machining capability.

---

WHY BUY USED DOOSAN PUMA 3100LY

Buying a used DOOSAN PUMA 3100LY can give a manufacturer access to a powerful multi-axis turning center at substantially less cost than purchasing a new machine.

The machine is particularly attractive for shops that need to manufacture complex components requiring both turning and milling. With Y-axis, C-axis, and live tooling, many parts can be completed in one setup, reducing handling, setup time, and the possibility of errors between separate machining operations.

The 3100LY also offers a strong combination of large chuck capacity, approximately 4-inch bar capacity, 30 HP spindle power, 2,800 RPM spindle speed, 12-station BMT65 turret, and 5,000 RPM live tooling.

When purchasing used, inspect the main spindle, C-axis, Y-axis, live-tooling spindle, turret, ballscrews, box ways, chuck, tailstock, control, coolant system, chip conveyor, and electrical cabinet.

It is especially important to test the Y-axis and live tooling because these features add considerable value to the machine.

HOW MUCH DOES A USED DOOSAN PUMA 3100LY COST?

The price of a used DOOSAN PUMA 3100LY varies substantially based on year, hours, spindle condition, control generation, bed length, tooling, options, and overall condition.

Current market listings provide useful reference points. A 2015 Doosan PUMA 3100LY is currently listed at approximately $120,000, while a 2019 machine was previously listed/sold at approximately $189,000. A historical market record also shows a 2015 PUMA 3100LY sold for approximately €92,000 in 2021.

For a general used-machine inventory page, I would use an estimated range of approximately $70,000–$190,000 USD, depending heavily on age and equipment.

USED DOOSAN PUMA 3100LY PRICE RANGE	ESTIMATED COST
Older / High-Hour Machine	$50,000 – $80,000
Standard Used Machine	$80,000 – $120,000
Good Condition / Well Equipped	$120,000 – $160,000
Newer / Low-Hour / Fully Equipped	$160,000 – $200,000+

For example, a 2015 machine listed at $120,000 provides a useful benchmark for a mid-life, well-equipped 3100LY.

Newer machines can command significantly more. A 2023 example with only around 2,200 cutting hours, Y-axis, live milling, long bed, tailstock, hydraulic steady rest, Renishaw probe, tool presetter, 1,000 PSI coolant, mist collector, chip conveyor, and automatic door had a stated full replacement cost of $340,000 when equipped.

For a typical used PUMA 3100LY in good operating condition, $80,000–$140,000 USD is a reasonable general estimate, while exceptionally clean, newer, low-hour machines with extensive options can be worth considerably more.

The actual value should be determined after checking cutting hours, spindle hours, Y-axis accuracy, C-axis indexing, live-tooling condition, turret operation, spindle runout, chuck condition, ballscrew wear, box-way condition, control alarms, maintenance records, tooling, chip conveyor, probing, and included accessories.
