Gear Hobbing

H100

The H 80-200 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.

H600

Features

Powerhouse for gears, shafts and screw-type workpieces.

The H 600/800 is a very stabile and rigid machine for the most demanding cutting taks. The machine employs all hobbing techniques (axial, radial/axial, tangential, diagonal) of spur and helical gearings using one or multiple cut technology with climb or conventional feed exploiting the different tool solutions available on the market.

The H 600/800 series is equipped with an exceptionally strong tool spindle drive and a very stabile and stiff tool head to live up to all gear cutting tasks. Depending on the application we deliver the series with special PowerCutting options.

The H 600/800 series can be automated with a standard ring loader for heavy workpieces. The gripper stroke is operated independently. The loader positions are freely selectable (cam-free) and can be saved in the Modul HMI / Operator Dialogue program for each specific workpiece.

Highlights

- Very stable and rigid structure

- Wet and dry cutting

- High performance hob head with 1000 Nm

- Up to 210 mm in hob diameter

- Direct drive work table with table plate options

- Standard and special workpiece support solutions

- Ring loader for heavy workpieces

- Compact layout with integrated auxiliary units

PowerCutting™

For workpieces with larger modules and tooth depths the H 600/800 is also available in a PowerCutting™ Version featuring an extra high-torque hob spindle with an enlarged swivel angle range. With the PowerCutting™ head the performance of inserted blade tools can be exploited to the maximum. Workpieces can be hobbed or milled depending on lot sizes and tool cost considerations. Additionally you can choose an extended counter column to cut longer and often slimer shapes like rotors or long shafts.

Especially when cutting larger modules, extreme tooth depths, high helix angles, though and ductile materials or very long or heavy workpieces the PowerCutting™ hob head and the special machine options become a very useful choice.

Highlights PowerCutting™

- PowerCutting™ Head with 1,500 Nm

- Larger hob diameters up to 300 mm

- Enlarged swivel angle for high helix angles

- Special worktable design

- Extended counter column for longer workpieces

- Workpiece support solutions for longer parts
