USED HAAS EC-1600 – 2011
The HAAS EC-1600 – 2011 is a large-capacity CNC Horizontal Machining Center (HMC) designed for machining large and heavy workpieces. The EC-1600 is part of Haas Automation’s EC Series and combines a large work envelope with a rigid 50-taper spindle, making it suitable for heavy-duty milling, drilling, boring, tapping, and multi-sided machining.
A documented 2011 HAAS EC-1600 is configured as a 4-axis horizontal machining center with a 64-inch pallet, 36-inch pallet width, 10,000-lb table capacity, 64″ X-axis travel, 40″ Y-axis travel, and 32″ Z-axis travel. It uses a CAT 50 spindle with a 30 HP motor and 7,500 RPM maximum speed and a 30-tool automatic tool changer. The machine is also equipped with through-spindle coolant, a gearbox, rigid tapping, chip auger, and a full 4th-axis rotary system.
The EC-1600 is particularly well suited to manufacturers machining large castings, housings, structural components, molds, dies, heavy equipment components, and other parts that require substantial workholding capacity. Its horizontal spindle orientation provides effective chip evacuation during deep cavity and heavy milling operations.
The machine’s 50-taper spindle and 2-speed gearbox provide the rigidity and torque needed for demanding cuts. The standard EC-1600 platform has a large machining envelope, while its optional integrated 4th-axis rotary platter provides access to multiple sides of a workpiece or tombstone without repeated manual repositioning. Haas lists the EC-1600 with a 64″ × 50″ × 32″ travel envelope on its current model specification, while individual 2011 machines can have different configurations, particularly regarding Y travel and 4th-axis equipment.

WHY CHOOSE HAAS EC-1600 – 2011
The HAAS EC-1600 – 2011 is designed for shops that need substantially more capacity than a conventional horizontal machining center.
Its combination of a CAT 50 spindle, 30 HP motor, 7,500 RPM spindle, 64-inch X-axis travel, 32-inch Z-axis travel, and 10,000-lb table capacity makes it well suited to large-part machining.
The integrated 4th axis is another major advantage. It allows large components or tombstones to be indexed around the rotary axis so that multiple sides can be machined without repeated manual repositioning.
The horizontal configuration also provides effective chip evacuation during deep-pocket milling and heavy material removal. For manufacturers working with large steel, cast iron, aluminum, or other industrial components, the EC-1600 provides the combination of rigidity, work envelope, and table capacity required for demanding machining.
WHY BUY USED HAAS EC-1600 – 2011
A used HAAS EC-1600 – 2011 can provide large-scale horizontal machining capability at a significantly lower acquisition cost than purchasing a comparable new HMC.
Key advantages include:
- 64″ X-axis travel
- 40″ Y-axis travel on documented 2011 configuration
- 32″ Z-axis travel
- 10,000-lb table capacity
- CAT 50 spindle
- 30 HP spindle motor
- 7,500 RPM spindle
- 2-speed gearbox

When purchasing a used EC-1600, buyers should inspect the spindle, gearbox, spindle bearings, X/Y/Z ballscrews, linear guides, rotary-axis backlash, table condition, pallet or fixture mounting surfaces, tool changer, CAT 50 spindle taper, coolant system, chip auger, hydraulic system, lubrication system, CNC control, and electrical cabinet.
For a machine with an integrated 4th axis, the rotary table should receive particular attention. Check indexing accuracy, backlash, brake operation, rotary drive condition, and overall table surface condition.
HOW MUCH DOES A USED HAAS EC-1600 – 2011 COST?
The price of a used HAAS EC-1600 – 2011 depends heavily on its configuration, condition, operating hours, spindle condition, 4th-axis equipment, tooling, coolant system, chip management, and maintenance history.
Current used-market information for EC-1600 machines indicates that 2010–2018 machines can occupy a broad price range, with large differences between standard machines and highly equipped, low-hour examples. UsedCNCExchange market information places many 2010–2018 EC-1600 machines broadly around $160,000–$280,000 USD, although individual machines can fall outside this range depending on condition and equipment.
For a used HAAS EC-1600 – 2011, a practical market estimate is approximately $150,000–$250,000 USD.
Machines toward the higher end may include:
- Low spindle hours
- Low cutting hours
- Full 4th axis
- 50-tool capacity
- Through-spindle coolant
- High-pressure coolant
- Chip conveyor
- Renishaw probing
- Additional tooling
- Excellent table condition
- Strong maintenance history
- Machine currently under power
The final selling price should be based on the actual machine configuration, spindle and axis condition, hours, included tooling, rotary-axis condition, maintenance history, and whether the machine can be demonstrated under power.
