Overview
The WFL M150 is a large-format multitasking mill-turn center from WFL Millturn Technologies, the Austrian company that essentially invented the MILLTURN concept. The M150 is designed for complete machining of complex, large-diameter workpieces in a single setup, combining heavy turning, 5-axis milling, drilling, boring, and gear cutting capabilities in one machine. This is a serious production platform targeting aerospace, energy, oil and gas, and heavy equipment industries.
The M150 handles workpieces up to 1,500 mm (59 in) swing diameter and turning lengths up to 6,500 mm (256 in) depending on bed configuration. The main spindle delivers up to 100 kW (134 hp) of continuous power with torque reaching 18,000 Nm, providing the muscle needed for heavy roughing of large-diameter forgings and castings. The milling spindle offers 12,000 RPM with 40 kW (54 hp) and uses an HSK-A100 taper for maximum rigidity during heavy milling operations on the turned surface.
What sets the M150 apart is the B-axis milling head with ±120 degrees of swivel range, enabling full 5-axis simultaneous machining on cylindrical workpieces. This allows complex aerospace components like landing gear, turbine shafts, and large valve bodies to be completely machined without removing the part from the machine. The integrated tool magazine holds up to 120 tools, and automatic tool changes keep non-cutting time to a minimum on multi-operation programs.
The M150 runs on Siemens SINUMERIK 840D sl with WFL's proprietary MILLTURN PRO programming environment layered on top. This software includes specialized cycles for crankshaft turning, deep hole drilling, gear hobbing, and thread whirling that are unique to WFL's multitasking platform. Pricing for the WFL M150 starts around $1,500,000 and can exceed $3,000,000 with extended bed lengths, automation, and specialty tooling packages. This is a capital-intensive machine that justifies its cost by eliminating 3-5 separate machines and the associated setups, fixturing, and work-in-process inventory. Competitors include the DMG Mori NTX 3000, Mazak INTEGREX e-420H, and Okuma MULTUS U5000.

Strengths & Limitations
Strengths
- 1,500 mm swing and up to 6,500 mm turning length handles the largest aerospace and energy components in a single setup, eliminating multiple machines and setups
- 100 kW main spindle with 18,000 Nm torque provides the power for heavy roughing of large forgings and castings that would overwhelm smaller mill-turn machines
- Full B-axis 5-axis milling capability with 40 kW HSK-A100 milling spindle delivers machining center-level milling performance on turned workpieces
- Integrated gear cutting, thread whirling, and deep hole drilling cycles eliminate the need for dedicated specialty machines
- WFL MILLTURN PRO software includes purpose-built cycles for crankshafts, landing gear, and turbine components that significantly reduce programming time
- Complete machining in one setup eliminates datum errors from multiple setups, critical for aerospace tolerance requirements
Limitations
- $1.5M+ starting price requires extremely high-value work and consistent utilization to justify; this is not a versatile job shop machine
- 45,000-80,000 kg machine weight demands serious foundation engineering, typically reinforced concrete pits, and heavy rigging for installation
- Siemens 840D sl with WFL overlay requires specialized training; operators cannot simply transfer from standard CNC lathe or machining center experience
- Long lead times for new machine delivery, typically 12-18 months from order to installation

Frequently Asked Questions
01
WFL exclusively manufactures MILLTURN multitasking machines and has done so since 1983. Unlike Mazak, DMG Mori, or Okuma who offer mill-turn as part of broader product lines, WFL's entire R&D and manufacturing focus is on large-format multitasking. This specialization shows in their purpose-built cycles for crankshafts, landing gear, and deep hole drilling, which are more refined than general-purpose mill-turn software from competitors.
02
The NTX 3000 is a significantly smaller machine with 830 mm swing vs the M150's 1,500 mm. They target different workpiece sizes. The NTX 3000 is better for medium-sized precision parts, while the M150 handles the large aerospace and energy components that simply cannot fit on smaller mill-turn platforms. For shops needing to machine parts over 1 meter diameter, the M150 or similar WFL models are the only practical multi-tasking option.
03
The M150's 100 kW spindle handles virtually any material including Inconel 718, titanium Ti-6Al-4V, high-alloy steels, stainless steels, and aluminum alloys. The high torque capability is particularly advantageous for roughing Inconel and titanium at the low surface speeds these materials require. WFL provides material-specific tooling packages and cutting parameter databases for aerospace superalloys.
04
New WFL M150 delivery typically takes 12-18 months from order. The machines are built to order in WFL's Linz, Austria facility, with each machine customized to the customer's specification regarding bed length, spindle options, and automation. Factory acceptance testing adds 2-4 weeks to the timeline. Used WFL machines occasionally appear on the market but are rare due to long service life and high retention among owners.
05
Yes. The M150 supports gear hobbing, gear milling, and gear skiving operations using the B-axis milling head and specialized WFL gear cutting cycles. While it cannot match dedicated gear cutting machines for high-volume gear production, it produces prototype and low-volume gears to the same quality standards. This capability eliminates a separate gear cutting machine for shops producing complete drivetrain components.
06
WFL offers integrated automation solutions including gantry loaders for shaft-type parts and robotic loading cells for chuck-type workpieces. Given the large part sizes the M150 handles, crane-based loading with automatic clamping is also available. The Siemens 840D sl control supports pallet management and job scheduling for reduced-manning operation. Most M150 installations include some level of automation due to the high machine cost demanding maximum utilization.
