Klingelnberg G 60

The Klingelnberg G 60 is the large-format member of Klingelnberg's G series bevel gear grinding line, extending bevel gear grinding capacity to 600 mm (23.6 in) reference diameter — covering the full range of large automotive truck and bus axle bevel gears, industrial mining and construction equipment ring and pinion sets, marine propulsion bevel stages, and large aerospace and defense gearbox bevel gear components.

At 600 mm maximum diameter, the G 60 grinds the ring and pinion gear sets for heavy commercial vehicle (HCV) rear drive axles used in heavy trucks, buses, and off-highway vehicles. These large bevel gear sets operate under extreme torque loads and require the same AGMA 13-15 / DIN 5 quality levels as passenger car axle gears but at much larger diameter and module — requiring a machine capable of maintaining grinding accuracy and wheel geometry at the larger scale.

The G 60 uses the same Klingelnberg CNC control and KIMoS closed-loop manufacturing integration as the G 27, enabling seamless process transfer between the two machines within a gear manufacturing facility that operates both passenger car and commercial vehicle axle gear lines. The CBN grinding wheel system provides the wheel life and surface quality required for production grinding at the heavy module (up to 12 mm) typical of large commercial vehicle bevel gears.

Klingelnberg's G 60 is installed at the major heavy commercial vehicle axle manufacturers — Dana Commercial Vehicle, Meritor, ZF, Carraro, and Elgin National Industries — as the production standard for heavy truck ring and pinion grinding. At $1,200,000-$1,800,000 new, the G 60 is a capital investment justified by sustained heavy-vehicle axle production volumes.
