VAJRA series Gear Hobbing Machines are 6 Axis Gear Less Gear Hobbing Machines with a stiff Electronic Gearbox (EGB) to give the best synchronization to generate the most accurate gear profiles. These machines are designed to be structurally rigid while UCRIDE ® technology ensures reduced vibration and higher dampening effect.

VAJRA Machines have been incorporated with the latest technology such as Direct-drive for Hob spindle and Work table. This enables our machine to achieve higher hob speeds with the latest cutting tools to give high productivity and quality. Hob head, having a precision spindle bearing arrangement, enables gear cutting. It is driven by a powerful built-in motor capable of delivering ample torque.

CNC Gear Hobbing Machines are advanced gear cutting systems designed for high-precision manufacturing of spur gears, helical gears, splines, sprockets, and worm gears. These machines ensure superior accuracy, high productivity, and reliable performance in modern manufacturing industries.
