Whether with 3 or 5 axes mounted on and driven by hydrostatic bearings, KERN Pyramid Nano is one of the most precise CNC machining centers in the world. By focusing on reliability in serial operation, this machine achieves ultra-precision manufacturing of industrial workloads.

Thanks to its hydrostatic drives and guides, the machine suffers virtually no wear in its linear axes. This means the quality and precision of all axes remain constant over extremely long time-frames. In conjunction with KERN’s proprietary thermal management system, you have a perfectly optimized tool at any time.

Among other things, the C 15 concept is based on the modern production technology of dry-cutting without the use of cooling lubricant, with an application range that is suited to smaller gearbox sizes. This machine is equipped with direct drives for the workpiece spindle and the tool spindle.

Thanks to continuous further development of the vertical concept, the Oerlikon C 30 bevel gear cutting machine sets new standards in dry processing. All of the bevel gear machines in this series are equipped with a thermostable, vibration-damping machine bed. The cutting machine utilizes an optimized axis arrangement, resulting in reduced traversing paths that significantly reduce the load on the drive components and stiffen the structure of the overall system at the same time. An integrated deburring tool also provides maximum productivity and maximum process safety using the PULSAR method. Use of the optional Power Skiving method makes it possible to achieve even greater machine flexibility and productivity.

The application range of the C 27 bevel gear cutting machine is ideal for the gearbox sizes found in passenger car and small truck applications. This machine is equipped with direct drives and is designed for cutting workpiece diameters up to 270 mm. The C 27 makes it possible to achieve cutting speeds that allow highly cost-effective dry-cutting even for a large number of cutter head starts and small numbers of teeth.

After 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 material. 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, particularly gear honing. The quality of such chamfers defines a new standard – with maximum repetitive accuracy.

Chamfered edges of gears prevent damage during workpiece transport, heat treatment cracks and gear wear. They facilitate the assembly process and improve the tool life. Chamfering 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 manufacturers, as well as in gear and engine manufacturing. The process can also be integrated into existing production systems.

The LGG machines are suitable for hob grinding and profile grinding. As standard, the machines are equipped with an external grinding head and can be supplemented with an internal grinding head.

The new LCS series offers a machine system for finish machining of hardened gears, characterized by its productivity and versatility. Two methods can now be used on a single machine: The LCS “Combi” Gear generating or profile grinding with dressable tools or plated CBN tools.

Gear grinding with dressable worms or form wheels has been a successful and well established technology for many years. Today, with the use of dressable sintered alumina tools, it has reached a remarkable level of performance. The CBN method, in comparison, stands out for its high machining consistency over the total tool life. With its exceptional tool life of up to 200 production hours, it offers a decisive advantage for high volume production. The Liebherr LCS series covers both technologies without limitations, opening up totally new possibilities for the user.

Is performance-related cutting possible on your machine? As nowadays the economical requirement is more important than ever, modern machines are required.

The Liebherr series LC ensures reliable processing of the required torques and cutting forces. The capability of modern CNC-Gear hobbing machines is emphasized herewith. Quality requirements such as accuracy, stability and temperature resistance are fulfilled with this machine concept. Stable processes are realized during pre- and finish hobbing.

With the machines LS 80 – LS 180 Liebherr is introducing a new series of production gear shaping machines. The performance and flexibility of these machines are optimized for high production requirements.

The machines are based on a common modular platform with proven components from the hobbing machine platform. Especially noteworthy are the direct table drive and the thermo-symetric, liquid-circulated machine bed.

For small face width parts, a RAPID version with max. 3000 strokes/min. is available. For tapered gears all models can be equipped with a swivel-type column for up to 12 swivel angle.

For the dry machining process, efficient and fast chip separation is a major prerequisite. The process energy involved and the disposal of hot chips should not adversely affect the geometry of the machine. The redesigned work area with stainless steel lining improves the chip discharge.

The extremely short cutting times require short loading and unloading times. Modular automation systems are available for various types of workpieces, supplemented by integrated and peripheral workpiece storage systems.

The foundation is the rigidity by the machine: The cast iron machine bed absorbs resulting process forces. The use of flat guides in all important linear axes provides additional damping. A high spindle rigidity is attained in the machining head using a special bearing concept, in which longer tool holders can be used – this is particularly important for machining internal gears.

In addition to the machine, the appropriate tool is crucial for a stable process. With its in-house tool development and manufacturing, Liebherr can design the optimal tool for every workpiece.

The planned process must be taken into account when designing tools. Thanks to intensive technological development and extensive tests with customers, Liebherr understands the interaction between machine and tool and is in a position to be able to offer a skiving machine, tools, and to provide the Skiving³ process.
