USED MORI SEIKI ZT-2500Y – 2007

The 2007 MORI SEIKI ZT-2500Y is a high-capacity CNC twin-turret, twin-spindle turning center with Y-axis and live tooling capability. Designed for multitasking production, the ZT-2500Y can combine turning, milling, drilling, tapping, and secondary-spindle operations in a single machine, reducing the number of setups required for complex components.

The ZT-2500Y is particularly attractive for manufacturers that need to machine components requiring operations on both ends. Its twin-spindle configuration allows a workpiece to be transferred between the main and sub spindle, while the twin-turret arrangement allows multiple tools to remain available for simultaneous or sequential machining operations. A documented 2007 machine is equipped with Y-axis capability, C-axis live tooling, twin turrets, twin spindles, a parts catcher, and chip conveyor.

The 2007 ZT-2500Y has a substantial machining envelope, with listings reporting approximately 27.7 inches of swing over the bed, 16.5 inches over the cross slide, and up to 13.7 inches of turning length. The main spindle has a 3.5-inch through-hole, while the machine is capable of spindle speeds up to approximately 4,000 RPM.

Its upper turret incorporates approximately ±2.8 inches of Y-axis travel, allowing milling and drilling operations to be performed away from the spindle centerline. The two 12-station turrets provide considerable tooling flexibility, with driven tooling available for the live-tooling operations.

A 2007 specification listing identifies Fanuc CNC control, while other ZT-2500Y examples from the same generation are equipped with Mori Seiki MSG-501/MSG-501III or related control configurations. The exact control on an individual 2007 machine should therefore be confirmed before purchase.

For shops machining complex turned components, the MORI SEIKI ZT-2500Y 2007 offers the major advantage of multitasking capability in a heavy-duty production platform.

---

MORI SEIKI ZT-2500Y – TWIN TURRETS

The ZT-2500Y uses two independent turrets, giving the machine substantially more tooling flexibility than a conventional single-turret CNC lathe.

Feature	Turret 1	Turret 2

Twin turrets can reduce cycle time by allowing different machining operations to be performed without repeatedly changing tools or waiting for a single turret to complete every operation.

---

MORI SEIKI ZT-2500Y – Y AXIS AND LIVE TOOLING

The Y-axis is what transforms the ZT-2500Y from a conventional turning center into a much more capable multitasking machine.

The upper turret provides approximately ±2.8 inches of Y-axis travel, allowing driven tools to move above and below the spindle centerline. This is useful for milling flats, slots, keyways, cross holes, off-center holes, and other features that cannot be produced efficiently with conventional turning tools.

Typical live-tooling applications include:

• Cross drilling
• Radial drilling
• End-face drilling
• Milling flats
• Slot milling
• Keyway machining
• Tapping
• Thread milling
• Off-center hole patterns
• Small contour milling

A documented ZT-2500Y configuration provides rotary-tool speeds of approximately 4,000 RPM, while other examples list driven-tool speeds as high as 6,000 RPM depending on configuration.

WHY BUY USED MORI SEIKI ZT-2500Y 2007

A used MORI SEIKI ZT-2500Y 2007 is an excellent option for manufacturers that need more than basic turning capability. Its combination of twin turrets, twin spindles, Y-axis movement, C-axis capability, and live tooling allows many complex components to be completed in fewer setups.

The biggest productivity advantage is the ability to perform operations on both ends of a component. Instead of removing the part from the machine and transferring it to another lathe for secondary work, the sub spindle can take over the component and allow additional operations to be completed.

The twin-turret design further increases productivity by providing two separate tool stations. With 12 stations per turret on documented machines, operators have considerable flexibility when setting up jobs requiring turning, boring, grooving, drilling, threading, and live-tool operations.

The Y-axis adds another important capability. Milling and off-center drilling operations can be performed directly on the turning center, reducing the need for a separate milling machine for certain components.

The machine’s substantial swing and turning capacity make it suitable for a wide variety of medium and larger turned components. Its approximately 3-inch bar capacity also makes it practical for production work involving larger bar stock.

For manufacturers purchasing used CNC equipment, the ZT-2500Y can therefore provide multitasking capability at a lower acquisition cost than buying a comparable newer twin-spindle Y-axis turning center.

HOW MUCH DOES A USED MORI SEIKI ZT-2500Y 2007 COST?

The price of a used MORI SEIKI ZT-2500Y 2007 can vary significantly depending on spindle hours, machine condition, control configuration, included tooling, live-tool equipment, chip conveyor, parts catcher, bar feeder, and overall maintenance history.

Because the ZT-2500Y is a complex multitasking machine, buyers should evaluate considerably more than the main spindle. The sub spindle, both turrets, Y-axis, C-axis functions, live tooling, and tool-changing systems all need to operate correctly.

Spindle condition should be one of the first priorities. Test the main and sub spindle throughout their operating ranges and listen for bearing noise, vibration, unusual temperature increases, or acceleration problems. The spindle taper and chuck condition should also be inspected.

The Y-axis should be moved through its complete range while checking for servo alarms, unusual noise, backlash, or positioning problems. Live tooling should also be tested at multiple speeds.

Both turrets should be cycled through all positions. Buyers should verify that every station indexes correctly and that the turrets clamp and unclamp properly.

The sub-spindle transfer operation is particularly important. A machine may appear to run correctly while still having problems with synchronization, positioning, or part transfer.

Buyers should also inspect the chip conveyor, coolant system, hydraulic system, lubrication system, electrical cabinet, way covers, ballscrews, linear guides, and chuck cylinders.

A well-maintained 2007 MORI SEIKI ZT-2500Y with good spindle condition, accurate axes, functioning twin turrets, reliable sub-spindle operation, and working live tooling can be significantly more valuable than a lower-priced machine requiring major repairs.
