The ChamferCut technology

Advantages of this process • Very precise chamfer geometry • Premium chamfer quality and reproducibility • No bulging or material deformation • Standard tooth-root chamfering • Established process in gear production • Very long tool life • ChamferCut tools can be re-sharpened approx. 20 times easily and

cost-effectively • Lower tool costs compared to alternative processes • Short amortization period due to low tool costs • Applications for gears with module 0.8 – 42 mm • 2nd cut not needed for gear hobbing –

longer tool life for the hobbing tool • Short setup times

Fast. Economic. Precise.This is the chamfering processAfter chamfering with the patented ChamferCut technology, no additional machining is necessary. There is no need for a second cut, which is often required during the deformation-based deburring process for the removal of build-up mate-rial. With the chamfering process, the exact chamfer form is produced. In contrast to deformation-based processes, the material structure is not affected. An optimal starting point is created for the subsequent finishing of hardened gears, par-ticularly gear honing. The quality of such chamfers defines a new standard – with maximum repetitive accuracy.

Precise, compact and cost-effective

Why chamfering gears?Chamfered edges of gears prevent damage during workpiece transport, heat treatment cracks and gear wear. They facili-tate the assembly process and improve the tool life. Cham-fering with ChamferCut delivers a high-quality chamfer with repetitive accuracy – and is more cost-effective compared to press deburring and deburring with end mills. Chamfering is very popular among car and commercial vehicle manufactur-ers, as well as in gear and engine manufacturing. The pro-cess can also be integrated into existing production systems.

Machine conceptThe LD 180 / 280 C is the most powerful and most compact stand-alone chamfering machine on the market. Workpieces with a diameter of up to 280 mm and up to module 6 mm can be chamfered down to the tooth root easily and with preci-sion. The machine is very easy to operate, and first centring is automatic.For increased ergonomic and simplified set-up, it is possible to swivel the chamfer hob head by 90 degrees so that the tool can be easily inserted from either operator side.

LD 180 / 280 C

Configurations and options

LD 180 / 280 CThe LD 180 / 280 C is available in two different versions. In the first version, without internal lift / tilt loader, the workpieces are loaded directly onto the machine table. Loading is pos-sible manually or using a robot. The integrated lift / tilt loader allows for removing workpieces from various transfer posi-tions. External transfer positions can be, for example, various conveyor systems. All drives of the lift / tilt loader are equipped with NC drives. There for sep-up and difficult adjustments are reduced to a minimum.

Without internal lift / tilt loader – for example, for robot loading With internal lift / tilt loader – for example, for belt connection

Optional: • Dry and wet machining• Left / right-handed operation• Counter column• Chip conveyor• Centrifugal function using the machine table• Additional stationary sensor for meshing

Set-up made easy!

Options for automation

1. Insert the workpiece, tool and clamping data or load the set-up data sheets automatically

2. Insert the meshing disc into the tool interface of the ChamferCut hob head

3. Select the teach-in cycle for determining the workpiece-specific gap position. Automatic positional orientation detection by the machine

4. Change over to new Cham-ferCut tool in an ergonomic position and acknowledge. Start automatic cycle. Enter correction values for optimizing the chamfer using the CNC controls system.

LD 180 / 280 C with robot loadingUsing a robot, workpieces can be loaded directly onto the table through to a fast lifting door. The solution can be implemented very easily,e.g. in cell concepts

LD 180 / 280 C with plastic chain conveyorThe LD 180 / 280 C can also be combined with various conveyor designs. The inte-grated lift / tilt loader allows for removing workpieces from various belt heights. This flexibility makes it possi-ble to integrate the LD 180 C / 280 C into existing manufac-turing systems quickly and easily.

LD 180 / 280 C with palletizing cells (LPC)The LD 180 / 280 C can also be combined with a pal-letizing cell. Thanks to this solution, the combination is a perfect fit for a manufac-turing concept with basket logistics.

LD 180 / 280 C with adaptable swivel loaderThe swivel loader (SSL) is de-signed for optimum produc-tivity and large batch sizes. The SSL ensures fast and safe loading and unloading of workpieces and addition-ally provides the best possible gripping of the workpiece. The SSL is typically used for work-pieces with short cycle times.


Integration into

existing production concepts

Option: cellular manufacturingCellular manufacturing in combination with a gear hobbing machine, a workpiece infeed and outfeed and a robot for handling workpieces.

Option: production lineThe LD 180 C can be installed downstream of the gear hobbing machine. This allows for chamfering workpieces economically and with precision.


The Liebherr solution:

Simultaneous chamfering

Chamfering made easy:• User-friendly software• Simple adjustment of corrections via CNC axes• Simple corrections at varying flank modifications• Dry and wet machining possible• Automatic loading with flexible loader principle (robot loading also possible)• Flexible automation, e.g. via plastic chain conveyor, palletizing cell

Gear hobbing machine LC 180 DC / LC 280 DCThe established LC 180 DC / LC 280 DC with integrated Cham-ferCut unit is a very compact gear hobbing machine. This inte-grated automation solution enables hobbing and chamfering of workpieces with a maximum diameter of 180 / 280 mm and a module of 5 mm during the machining process.

Gear hobbing machine LC 300 DC With the LC 300 DC gear hobbing machine, workpieces with a maximum diameter of 300 mm can be produced very eco-nomically, with good gear quality and precise chamfer qual-ity. Workpieces up to module 6.5 mm can be hobbed and simultaneously chamfered.

Chamfering machines LD 180 C and LD 280 CThe LD 180 C and LD 280 C are compact stand-alone ma-chines whose main task is the chamfering of gears. They can be integrated easily, quickly and cost-effectively into all exist-ing manufacturing lines.

Chamfering in the working areaThe classic ChamferCut process with the chamfer cutters on the hob arbor can be retrofitted on all existing Liebherr gear hobbing machines with the Siemens 840 D generation of control systems and higher.
