Klingelnberg P 40

The Klingelnberg P 40 is a CNC bevel gear cutting machine purpose-built for the production of Klingelnberg Cyclo-Palloid spiral bevel and hypoid gears with workpiece diameters up to 400 mm. Designed for automotive axle, differential, and gearbox manufacturers, the P 40 delivers the exceptional surface quality and dimensional consistency required for quiet-running, high-efficiency bevel gear sets in passenger vehicles and light commercial applications.

The P 40 is engineered around Klingelnberg's continuous face hobbing process, which produces bevel gears with superior surface finish and uniform tooth geometry in a single setup without the need for lapping in many applications. The machine features a highly rigid polymer concrete base (Mineralit) that provides outstanding vibration damping and thermal stability compared to traditional cast iron structures. All rotary axes are equipped with torque motors for backlash-free, high-dynamic positioning, while linear axes use precision ball screws with glass scale feedback for sub-micron positioning.

Klingelnberg's KIMoS (Klingelnberg Integrated Manufacturing of Spiral Bevel Gears) software platform is natively integrated, enabling seamless data flow from gear design through cutting, grinding, and metrology. The P 40 can be directly linked to Klingelnberg's P-series gear measurement centers for closed-loop manufacturing and automatic correction of tooth geometry deviations. This digital integration eliminates manual setup iterations and dramatically reduces time to first-article approval.

The P 40 is the mid-range machine in Klingelnberg's P-series cutting line, sitting between the compact P 26 and the larger P 65. Its capacity and throughput make it the benchmark choice for high-volume automotive differential and axle gear production, and it is widely deployed by Tier 1 automotive suppliers worldwide.
