(Kempten, Germany) to develop a CNC production
hobber using the pick-upspindle VTL design.
Up to eight part changes a day are made on the Gleason
hobber. The confidence in the precision and performance of the machine has led to the elimination of making trial cuts.
When he sought a flexible, high production CNC
hobber, Mr Young looked to The Gleason Works, Rochester, NY.
The indexing system must have mechanical and electronic integrity many times that of its roughing brother, the
hobber. To think that one could simply modify a modern
hobber and turn it into a grinder, however, is a misunderstanding of the kinematics required.
Though a relative new-comer to the larger cylindrical gear market, Gleason staked out a presence with the introduction of the Phoenix 125 Gear
Hobber three years ago to the automotive market to do the initial milling or cutting of cylindrical gears in the 50mm to 200mm(2" to 8") sizes that are the typical range of sizes for front-wheel drive cars.
Liebherr has designed a prototypical gear
hobber (the LC 82 model) that delivers increased speed and power required plus sufficient reserves for further increase in performance that may be required.
The 125 GH CNC six-axis gear
hobber for production of cylindrical gears is capable of hobbing gears from 0.25" to 7.9" in diameter.
