Vertical Hobbing

H 80-200 Vertical Gear Hobbing Machine

The H 80/100/130/160/200 series is the latest version of our hobbing machine line for small automotive applications, specially engineered for automotive applications. These machines have been designed for dry cutting applications in particular, although using oil or emulsion is not a problem. Chips are conveyed cleanly from the work area by means of a chute, which is steep and smooth in design to prevent any build up. The hob head is housed within the tool column, which is tightly fastened to the sturdy machine bed. The tailstock is located on the tool column above the hob head, leaving the work area remarkably free for workpiece loading and unloading operations.

To cater for your line automation needs, the machine is available with a standard, direct-driven double gripper loader. Placing a machine in close proximity to your workpiece conveyor belt, in fact, requires no further automation other than that provided by the completely integrated solution. All peripheral units are easily accessible and maintenance-friendly (including pneumatics, hydraulics, electrics and chip disposal).
The machines can either be used as high-speed mass production tools or as power houses to obtain high-torque cutting performances, thanks to the different drive variants available. Moreover, the direct drive technology incorporated in this series makes your machine a safe investment over time, since any future tool developments can be fully exploited.

Fast and easy operator guidance throughout the whole process is guaranteed by the latest Siemens Sinumerik 840 D dialogue software, and the ability to make flexible tooth flank and crowned root corrections, ensures optimum roughing results for pre-shave, pre-grind or pre-hone applications.

H 600-800 Vertical Gear Hobbing Machine

The H 600-800 is a very stable and rigid machine for the most demanding cutting taks. The machine employs all hobbing techniques (axial, radial/axial, tangential, diagonal) of spur and helical gears using one or multiple cut technology with climb or conventional feed exploiting the different tool solutions available on the market. For workpieces with larger modules and tooth depths the H 600 is also available as a reinforced version, featuring an extra high-torque hob spindle, an enlarged swivel angle range and an extended counter column to cut long and slim shapes like rotors or longer shafts.
The H 600-800 can be equipped with a stable ring loader for heavy workpieces.

Features

・Very stabile, rigid machine
・All hobbing techniques
・Spur and helical gearings
・Single or multiple cut technology
・Climb or conventional feed
・Exceptionally strong tool spindle drive
・Sturdy, stiff tool head
・Special PowerCutting options
・Ring loader for heavy workpieces

H 900-2300 Vertical Gear Hobbing Machine

The H 900-2300 is designed for large gear milling and hobbing applications. The large H series cuts straight and helical gears; crowned and tapered gears; worm gears; cluster gears and special profiles (such as compressor-type rotors); oval gears; herringbone gears (gears with a double helix); and internal gears. This series can utilize any cutting technology available on the market, from single-cut form milling cutters, to HSS or carbide tools for wet or dry hobbing applications, chamer-hobbing. With the optionally available internal milling head intenal gears can be cut as well.

Features

・Straight and helical gears
　Crowned and tapered gears
　Worm gears
　Cluster gears and special profiles
　Oval gears
　Double helical gears
・Any cutting technology available
