Overview
The Forest-Line Alize is a compact, high-dynamic 5-axis machining center from Forest-Line Group that addresses the smaller end of the company's aerospace and precision industrial machining portfolio. Where the Atlas and Forest-Line's large gantry systems are engineered for widebody aerospace panels and major structural components, the Alize is designed for smaller aerospace structural parts — ribs, brackets, machined fittings, integrally stiffened panels in smaller format, and complex precision components in aluminum, titanium, and specialty alloys. The Alize platform brings Forest-Line's 5-axis engineering philosophy — high dynamic stiffness, precision thermal management, and simultaneous 5-axis contouring capability — into a more accessible machine size and price point.
The Alize is built around a moving-column or bridge-type architecture depending on configuration, with a working envelope typically in the 2,000–4,000 mm x 1,000–2,000 mm range. This size range is directly relevant to aerospace rib and frame machining — components that are large enough to exceed conventional machining center envelope but small enough that a full gantry portal machine would be physically oversized and economically unjustifiable. The machine's 5-axis head uses Forest-Line's compact fork-type or articulated head unit providing ±100° A-axis and continuous C-axis rotation, enabling the full simultaneous 5-axis contouring required for complex aerospace fittings and integrally machined structural pockets.
Forest-Line equips the Alize with a high-speed electro-spindle optimized for aerospace aluminum — the dominant material in the machine's application portfolio. Spindle speeds up to 24,000 RPM with HSK-A63 tooling enable high feedrate aluminum removal strategies appropriate for pocketed aerospace structure where material removal rate and surface quality are both critical. The Siemens 840D sl control with RTCP transformation and Forest-Line's aerospace-specific cycle library manages the 5-axis contouring, tool compensation, and process monitoring functions. An optional high-torque spindle configuration is available for customers with a significant titanium workload.
The Alize occupies a competitive space that includes machines from DMG Mori (DMU 125 P duoBlock), Hermle (C 42, C 52), Starrag (STC range), and similar compact-to-mid-size 5-axis machining centers with aerospace application capability. Forest-Line differentiates the Alize through its specifically aerospace-oriented engineering — the machine is not a general-purpose 5-axis machining center adapted for aerospace use, but a purpose-designed aerospace machining platform that happens to be smaller than the company's gantry systems. This distinction matters to aerospace customers who value the application knowledge embedded in the machine's structural and dynamic design.

Strengths & Limitations
Strengths
- Purpose-designed for aerospace structural part machining rather than a general 5-axis machine adapted for aerospace — Forest-Line's application-specific structural and dynamic engineering benefits customers with demanding aerospace programs
- High-speed electro-spindle at up to 24,000 RPM with HSK-A63 enables the aggressive aluminum removal rates required for efficient aerospace rib, bracket, and fitting production
- Compact form factor relative to Forest-Line's large gantry systems makes the Alize physically accessible to smaller facilities and Tier 2 aerospace suppliers who cannot accommodate a full portal machine
- Simultaneous 5-axis contouring with Forest-Line's RTCP-enabled Siemens 840D sl control provides the capability required for complex aerospace fittings and integrally stiffened pocket features
- Forest-Line's proven Airbus supply chain reference base extends to the Alize — customers benefit from Forest-Line's aerospace application knowledge regardless of machine size
Limitations
- Premium price point of $1.5M–$4M places the Alize above general-purpose 5-axis machining centers from DMG Mori, Hermle, or Makino that serve the same working envelope — the premium requires an aerospace application focus to justify
- Forest-Line's sales and service organization is smaller than DMG Mori or Makino — service response outside Western Europe may require more advance planning, particularly for customers in North America or Asia-Pacific
- Narrower tooling and automation ecosystem compared to high-volume 5-axis platforms from Japanese and German mainstream builders — customers benefit from Forest-Line's aerospace expertise but sacrifice ecosystem breadth

Frequently Asked Questions
01
Forest-Line's 5-axis gantry range is differentiated by scale: the Alize is the compact model for smaller aerospace structural parts (ribs, brackets, fittings, smaller panels) in the 2,000–4,000 mm x 1,000–2,000 mm envelope. The Alcor is the entry-level gantry for medium aerospace structure. The Atlas is the mid-to-large gantry for major aerospace structural panels and large monolithic parts. All three use Forest-Line's core 5-axis aerospace machining technology — the Alize brings that technology to a more accessible machine size and price point suitable for Tier 2 aerospace suppliers and smaller structural part families.
02
Yes, though the standard Alize high-speed configuration is optimized for aluminum. An optional high-torque spindle configuration (higher torque, lower max RPM, ISO 50 interface) is available for customers with significant titanium workload. Titanium machining requires different speeds, feeds, and tooling strategies than aluminum — the high-torque head provides the appropriate cutting force capacity. For mixed aluminum and titanium production, discuss automatic head changing options with Forest-Line to enable material-flexible production on a single machine.
03
Hermle C 52 and DMG Mori DMU 125 P are well-established 5-axis machining centers in a similar working envelope to the Alize. Both are excellent general-purpose 5-axis machines with broader tooling and automation ecosystems and lower price points than the Alize. The Forest-Line Alize differentiates through its specifically aerospace-oriented structural and dynamic design, Forest-Line's Airbus application reference base, and the aerospace-specific cycle library in its Siemens 840D sl control. For shops whose primary work is aerospace structural aluminum and titanium, the Alize's application focus is a genuine advantage. For general-purpose 5-axis work, Hermle or DMG Mori provide better value.
04
The Alize supports pallet changing systems for production automation, with Forest-Line able to integrate the machine with both Forest-Line-designed pallet pools and customer-specified automation cells. Robotic workpiece loading and unloading can be integrated through standard interface provisions. For aerospace production environments running repeat-part family work, pallet automation is a common configuration. Tool management systems with tool life monitoring and adaptive feed control are standard on the Siemens 840D sl platform.
05
Forest-Line Alize lead time is typically 12–24 months from order, depending on configuration complexity and the current production queue. This is shorter than the 24–36 months typical for large gantry Atlas machines but still requires forward planning. Buyers with specific program start dates should initiate the procurement process at least 18 months in advance to allow for the machine specification/design phase, manufacturing, factory acceptance testing, and installation. Forest-Line's sales team can provide current lead time estimates during the evaluation process.
