With the LC 180/280 DC, the ChamferCut device is integrated on the operator side. This device has been enhanced in terms of user-friendliness. As such, the machine operator has unobstructed accessibility to both machining positions. Chip removal has also been significantly improved. Using the proven Liebherr ringloader concept, the workpiece can be transferred quickly and efficiently between the gear hobbing and chamfering machining positions. Chamfering by ChamferCut or FlexChamfer therefore takes place parallel to gear hobbing. The special feature of the chamfering unit is that it is controlled using 6 CNC axes as standard. Settings or corrections and adjustments for varying lead corrections can be executed quickly and easily using the user-friendly software.

As an alternative, we offer the new FlexChamfer technology. The gears can be chamfered quickly and efficiently using a standard milling tool. The movements of the tool are also fully NC-controlled, ensuring high repeatability and chamfer quality. This process is ideal for workpieces with interfering contours or when there is a very large part variance and small batch sizes.

• Parallel gear hobbing and defined deburring / chamfering
• Dry and wet machining possible
• Precision chamfering geometry
• Highest chamfer quality and repeatability
• No bulging or material deformation
• Tooth root chamfering as standard
• Very long tool life ChamferCut tools can be easily reground 15 to 20 times at low cost
• Lowest tool costs per workpiece compared to traditional processes
• Short amortization period thanks to low tool costs per workpiece
• wide module range from 0.8 to 42 mm
• 2nd cutting during gear hobbing is unnecessary thereby increasing tool life quantity at the gear hob
• Short setup times

• Flexible and universally applicable
• Ideally suited for workpieces with interfering contours
• Precision chamfering geometries
• Highest repeatability
• Simple NC corrections possible
• Use of standard tools (quickly available from stock)

For gear manufacturing machining, a workpiece drive with absolutely zero backlash is required. The table drive with spur gears is available when using conventional technology. For high performance cutting (HPC) an ultra-dynamic direct drive is available which satisfies all requirements with respect to speed and precision.

Thanks to an integrated complete stainless steel housing (optional), thermal influences that normally occur in dry machining can be minimized. This ensures consistent machining results and exceptionally high process reliability. In addition, chip accumulation can be prevented. The easy and fast cleaning of the machine is another benefit.
