PHC 150 - 6-Axes High Speed Gear Hobber
(The PHC Series)
in diameter; two Gleason CNC high-speed gear hobbers
; an Okuma LB 4511/1000 turning center; and a Pfauter P-900 six-axis CNC gear hobber
The company debuts a Linux operating system CNC in January, along with a gear hobber
and a grinder software package.
* GS:H gear hobber
line consists of machines with capacities of 6[inches] to 36[inches] dia gears.
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.
For parallel-axis gears, the Gleason 125GH CNC gear hobber
provides high-speed hobbing in a small footprint with the rigidity to take full advantage of TiN and TiCN-coated tooling.
Gleason introduced its Phoenix 125 GH CNC gear hobber
. It features a Y-axis carrying the work-head column rather than the more traditional design where the Y-axis is integral with the hob head.

Almost all manufacturers dealing with gear creation will show their wares, including gear hobbers
; gear shapers; gear cutters; and gear shavers.
Drake now offers powertrain and steering manufacturers four types of machines for producing steering and gear box components: gear grinders for finish grinding pre-cut gears in one setup with fast changeover; worm grinders for producing steering worms and other complex geometries needing up to 90 deg power helix; gear hobbers
for roughing with auto load and probing; and rack mills that can mill steering racks in 35 sec to a 0.4 Ra cut tooth finish with magazine load and unload.
