Overview

The Mazak INTEGREX e-1250V/8 is one of the largest production mill-turn centers in Mazak's INTEGREX e-series, designed for heavy-industry applications where large-diameter, heavy workpieces must be fully machined in a single setup. With a maximum turning diameter of 1,900 mm (74.8 in) and a maximum turning length of 3,050 mm (120 in), the e-1250V/8 addresses the oversized shaft, casing, and structural component requirements of energy, aerospace, and power generation manufacturers.

The machine is built around a large-bore turning spindle with an A2-20 spindle nose and 127 mm (5 in) bar capacity. Spindle speed reaches 1,000 RPM on the main spindle — appropriate for the large chuck sizes and heavy part masses involved. The spindle motor delivers substantial torque for interrupted cuts and facing operations on large castings or forgings. A programmable tailstock supports long-shaft work up to the full 3,050 mm machining length.

Milling capability is provided through a B-axis milling spindle rated at 10,000 RPM and a dedicated milling motor. The B-axis swings 220 degrees, enabling under-spindle, angular, and compound-angle milling operations that would otherwise require secondary HMC or VMC setups. Y-axis travel is 380 mm (14.96 in), providing substantial off-center reach for large flanged parts with eccentric features. The ATC holds 40 tools standard, expandable to 80.

Control is MAZATROL SmoothG or SmoothAi on current build machines, with conversational programming that reduces setup time for one-off large parts. The machine weighs approximately 50,000 kg (110,000 lb) and requires a substantial foundation — pre-engineered floor plans are available from Mazak for new installations. Axis rapids run at 20 m/min on X and Z due to the moving mass involved, with full contouring on X, Z, B, and C axes simultaneously.

The e-1250V/8 competes directly with the DMG Mori NTX 3000 and Okuma Multus U5000 for large shaft and energy sector work. It is priced at the top of the mill-turn market, typically $1.2M-$2.5M new depending on configuration. Shops that can fill this machine with large aerospace structural parts, turbine shafts, or offshore drilling component work will find it eliminates 3-4 machine moves and substantial fixturing investment. Mazak offers turn-key application engineering support for first installations in new industries.

Strengths & Limitations

Strengths

1,900 mm maximum turning diameter handles the largest shafts, rotors, and structural castings in energy and aerospace without transfer
3,050 mm turning length enables complete machining of long turbine shafts and drive shafts in one clamping
B-axis milling with 380 mm Y-travel performs eccentric features and complex flange drilling on large parts that cannot be moved to secondary machines
Mazak MAZATROL SmoothAi with conversational programming reduces programming time on one-off heavy parts compared to pure G-code approaches
Turn-key application engineering from Mazak de-risks first installation in new industries

Limitations

50,000 kg machine weight requires substantial foundation engineering and deep pit construction in many facilities
$1.2M-$2.5M price demands very high machine utilization to achieve acceptable ROI — difficult to justify without a dedicated large-part program
1,000 RPM maximum main spindle speed limits surface footage on smaller-diameter features when chuck capacity is not the constraint
20 m/min rapids are slow relative to smaller mill-turn centers, adding non-cutting time on complex multi-operation parts
Long lead times (12-18 months) for configured machines can delay program starts

Best For

Energy and power generation manufacturers machining turbine shafts, generator rotors, and compressor casings over 1 meter diameter Aerospace tier-1 suppliers producing structural frames, landing gear components, and engine casings requiring combined turning and milling Oil and gas equipment manufacturers machining drilling risers, valve bodies, and wellhead components in alloy steels Defense contractors producing large weapon system structural and drive train components to strict tolerances

Frequently Asked Questions

01 What is the maximum part diameter the e-1250V/8 can swing?

The maximum turning diameter is 1,900 mm (74.8 inches). This is the swing over the bed — actual chuck capacity depends on the chuck size selected. The A2-20 spindle nose allows very large face drivers and chucks for castings and forgings.

02 How does it compare to the INTEGREX i-series for large work?

The e-series is better suited for very large heavy work. The i-400 and i-630V top out at around 630-730 mm diameter. The e-1250V/8 at 1,900 mm serves a completely different market — turbine-scale parts rather than aerospace structural parts. Expect significantly lower RPM and much higher torque in the e-series.

03 Can the e-1250V/8 handle titanium and Inconel?

Yes. The machine is built for heavy interrupted cuts in alloy steels and titanium, with high-torque spindle motors sized for the cutting forces involved. Tooling selection and coolant strategy are critical — Mazak application engineers provide cutting parameter guidance for aerospace alloys on initial installation.

04 What foundation work is required?

Mazak provides a machine foundation drawing for each installation. The 50,000 kg machine typically requires a reinforced concrete pad 800-1,000 mm deep with vibration isolation mounts. Pre-site assessment by a Mazak engineer is standard practice before delivery.

05 What is the typical lead time for a new e-1250V/8?

Configured machines typically run 12-18 months from order to delivery. Stock or near-stock configurations are rare at this scale. Factory witness tests are standard before shipping. Plan for 2-3 months additional for site preparation, installation, and training.
