The fully automatic CNC-controlled P 16 precision measuring center is designed as a compact unit for the workpiece diameter range up to 160 mm. The machine is used to inspect cylindrical gears, pinion type cutters, worms and worm wheels, hobs, bevel gears, general dimension, shape, and positional deviations of axially symmetrical workpieces, cam and camshaft measurement and rotor measurement.

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.

Mägerle MFP series – The long-distance machine With the MFP series, Mägerle comprehensively covers the requirements for flat and profile grinding machines. These machines specialise in creep feed grinding as well as profile and flat grinding operations using the pendulum method. They demonstrate their full performance potential in applications where workpieces must be produced in large batches and with high stock removal volumes in the customary high Mägerle precision. Thanks to their robust construction, the machines in the MFP series also master these requirements in hard 24/7 continuous operation. The Mägerle MFP series has a modular design. Table lengths and vertical strokes across a large range can be freely combined with different additional axes and special components. This flexible modular system enables diverse machine configurations, which are precisely geared to the specific user requirements.

Processes such as grinding, cutting and drilling can be achieved to absolute perfection in a single clamping. High productive benefit with simple operation are the result. The intelligent design principle takes production quality, safety and cost efficiency to a new level.

The MGC grinding centre with stationary table is designed for the high-precision processing of large and heavy workpieces. With a broad range of different table sizes and vertical strokes, this machine meets the highest requirements in respect of load bearing capacity.

The standardised Mägerle modular concept can be freely configured to provide individual solutions. Grinding centres which are completely tailored to specific customer requirements are developed within the scope of a proven product range. Single and multiple spindle systems with a horizontal or vertical arrangement can be combined as desired with stationary workpiece carriers, swivelling table or rotary table, in any dimensions. The result in all cases is a made-to-measure tool which fulfils the high requirements on manufacturing quality in the automotive, aviation and hydraulic sectors, in turbine construction and mechanical engineering, as well as in the roller bearing and tool industry, with optimal cost effectiveness.

Technical innovation and quality-oriented thinking are the core competencies of successful businesses.

Both competencies are not possible without metrology.

Measurement instruments verify research and development results and document product quality.

Without continuous advancement of metrology there would be no technical progress.
