Klingelnberg P 65 CNC Bevel Gear Cutting Machine

The Klingelnberg P 65 is a high-precision CNC bevel gear cutting machine built to manufacture spiral bevel and hypoid gears with workpiece diameters up to 650 mm. As part of Klingelnberg's Höfler-derived bevel gear cutting family, the P 65 employs the Palloid and Klingelnberg cyclo-palloid cutting systems — face hobbing processes that generate continuous tooth flank geometry with exceptional surface finish and load-carrying capacity directly applicable to heavy-duty automotive and industrial gearbox applications.

The machine is driven by a six-axis CNC architecture running on the Klingelnberg KNC control platform, which provides seamless integration with the company's KIMoS (Klingelnberg Integrated Manufacturing of Spiral Bevel Gears) software. KIMoS enables closed-loop manufacturing — importing gear design data, generating machine settings, and validating output geometry through Klingelnberg's own gear measurement centers — making the P 65 a natural fit for complete bevel gear manufacturing cells.

Structurally, the P 65 features a thermally stable Meehanite cast iron base with finite element-optimized ribbing to suppress vibration during high-speed face hobbing cuts. The cutter spindle and work spindle both use direct-drive motors with integrated encoders, eliminating gear trains and ensuring consistent angular positioning across millions of cycles. This architecture supports the tight index accuracy required for DIN class 4–6 bevel gears used in aircraft, wind turbines, and performance automotive differentials.

For high-volume production environments, the P 65 accepts robot and gantry loading integration, and its oil-mist filtration and chip conveyor system are designed for unmanned multi-shift operation. With a proven installed base in European automotive transmission plants and a global service network, the Klingelnberg P 65 represents one of the most capable platforms available for large-diameter precision bevel gear production.
