Total Accuracy, Continuous Innovation
In the aerospace sector, accuracy is not optional, it is both a technical and economic necessity. Every component, from fuselage panels to blades and blisks, requires high-tech machining and absolute repeatability. This is where the Gruppo Parpas approach comes into play. For over 70 years, we have partnered with aerospace industries, providing solutions designed to ensure consistent performance, flawless surface quality, and adaptability to the most advanced materials.
An Evolving Industry
The aerospace industry is continually evolving. Growth in global demand, sustainability priorities, and expansion in defence and space markets are driving the design of lighter, more efficient aircraft using composites and superalloys. Machining centres must therefore meet extreme requirements in accuracy, dynamics, and stability. Gruppo Parpas continues to invest in R&D, collaborating with leading Tier 1 companies to anticipate tomorrow’s production needs.

Structural Components: Where Rigidity, Accuracy and Flexibility Coexist
XS – The Gantry Milestone
The XS high-speed gantry machining centre has been a technological benchmark in the sector for over 25 years. Equipped with TTM technology on the X-axis for feedrates up to 80 m/min, it combines high dynamics with precision, even on large components. Its advanced thermo-stabilisation system ensures extreme accuracy in environments with temperature fluctuations.
The XS can be configured with an automatic head changer or electrospindle changer and offers multiple working configurations: dual zone, dual RAM, and dual gantry. Integration with milling/turning tables and pallet-changing systems significantly improves flexibility. Similar capabilities are available in the SPEEDLINER model, which is equipped with linear motors on all axes.

ACTIVE: High Speed, High Surface Quality
ACTIVE FIVE, a fixed portal moving table machining centre by OMV, is ideal for machining spars, ribs, beams, landing gears, and skins. Its compact, rigid structure, combined with linear motors and a two-axis head, enables 5-axis machining with feedrates up to 60 m/min. The result is a perfect balance of speed, precision, and stability, significantly reducing cycle times.

Motor Components: Performance Without Compromise
UNIKA – One Machine, Many Solutions
UNIKA BLADE and UNIKA BLISK are Gruppo Parpas’ solutions for producing critical jet engine components. The machine’s core features a full linear motor system, enabling feedrates up to 60 m/min and high-quality surface machining.

The mobile column structure maintains rigidity during high-speed machining, while 3- or 5-axis capability and a wide range of electrospindles (produced in-house since 1999) ensure flexibility and reliability. These optimisations reduce cycle times by up to 30% compared to alternative systems.
For other motor components such as cases, diffusers, air intakes, and lipskins, Gruppo Parpas offers DIAMOND and ROLLER models, suitable for various dimensions and geometries.
Integrated Predictive Quality: DRONEX
In the aerospace industry, quality means continuous inspection and error prevention. DRONEX, Gruppo Parpas’ patented technology, addresses this need. Based on 6D Real-Time Volumetric Precision (6D-RVP), it allows real-time monitoring of geometric deviations.
Active control across six dimensions enables dynamic calibration, reducing waste and improving process consistency. Integrated into a QMS system, DRONEX can transform any machining centre into an autonomous metrology machine, drastically enhancing productivity and part quality.
Real Applications, Real Advantages
Gruppo Parpas’ technologies are employed by aerospace companies worldwide, reflecting our extensive experience in the field. We begin by discussing customers’ requirements, enabling the design of highly customised systems that meet the most demanding production needs.
Thanks to a wide range of flexible, powerful, and accurate machining centres, which can be integrated with automated solutions and advanced metrology technologies like DRONEX Gruppo Parpas remains a strategic partner for those seeking measurable results in quality, productivity, and reliability.
