Parpas XT 5-Axis

The Parpas XT 5-Axis is Parpas's dedicated simultaneous 5-axis gantry machining center, engineered specifically for the aerospace, die and mold, and precision engineering sectors that require full 5-axis interpolation at large scale. Where many large gantry machines offer 3+2 indexed positioning as their 5-axis capability, the XT 5-Axis platform is architected from the ground up for continuous simultaneous 5-axis contouring — a distinction that matters critically for aeronautical structural parts, turbine airfoil features, and complex die cavity surfaces that require the tool to constantly reposition its angular relationship to the workpiece surface during cutting.

The XT 5-Axis gantry features Parpas's proprietary high-speed swivel head technology, combining a compact, stiff A/C or B/C axis fork head with a high-speed electrospindle capable of reaching 24,000–30,000 RPM. The head design emphasizes rotary axis stiffness and damping to minimize tool deflection during simultaneous 5-axis cuts, a technical challenge that separates purpose-built 5-axis gantry systems from converted 3-axis machines with add-on tilting heads. The XT architecture places the rotary axes as close to the tool tip as possible, minimizing the TCP (tool center point) error that grows with distance from the rotary axes.

The machine's structural design employs a cross-rail gantry configuration with Parpas's Italian-engineered polymer concrete or cast iron structural elements, optimized for thermal stability and vibration absorption during extended 5-axis contouring cycles. Linear axis drives use precision ball screws or linear motors depending on the travel and application, and rotary axes are driven by direct-drive torque motors for zero-backlash positioning and dynamic 5-axis interpolation performance.

Control is provided by Heidenhain TNC 640 or Siemens Sinumerik 840D sl with full RTCP (rotary tool center point) functionality — the software compensation that makes simultaneous 5-axis machining practical by automatically compensating for the pivot length and rotary axis geometry during contouring. Both control platforms are well-supported in aerospace and precision engineering CAM environments, with post-processors available from all major CAM vendors.

The Parpas XT 5-Axis occupies the high-performance end of the large-format 5-axis gantry market, competing with machines from Handtmann, Forest-Liné, and SNK in the aerospace structural machining segment. For buyers machining wing skins, bulkheads, spars, and complex engine mount structures from aluminum alloy billet or titanium, the XT 5-Axis delivers the simultaneous 5-axis performance and structural scale that the application demands.
