Gear cutting and finishing machines

The innovative solution for complete machining of rotationally symmetrical and cubic parts, based on proven designs. The modular concept allows the machine to be produced with 1 or 2 independent spindles and with one or two cross slides. The PV³ combines technologies such as turning, drilling, thread cutting, milling, skiving, grooving or grinding and gear hobbing as well as hard turning and grinding including integrated quality check in a monitored process, all in one machine. Unique, patented tool carriers allow this high application flexibility in the part diameter range from 400 to 1,600 mm.

What makes SynchroFine unique is the compact design of all units. All units are mounted on a natural granite bed for optimal thermal and vibration-damping characteristics.

The digital and directly driven tool and workpiece spindles guarantee backlash-free drive and load reversal, as there is no need for mechanical transmission elements, such as toothed belts, gears, etc.

The machine is designed as a self-loading unit (pick-up principle) and is basically equipped with integrated handling units. The components can be fed individually. From simple manual loading through automation solutions with conveyor belts to robot cells with integrated camera functions from our sister company rbc robotics, we can use a wide range of automations according to your preferences and needs.

For even more efficiency, we can equip the system with two workpiece spindles in order to reduce non-productive times to a minimum.

The digital recording of operating parameters is also standard with the SynchroFine. It can be further expanded through various modules in order to analyze process data and thus continuously optimize processes

The PITTLER SkiveLine is a new type of skiving center with automation cell for complete machining of larger components up to a diameter of 1250mm. Based on the proven PITTLER vertical series, the new platform is geared to PITTLER's advanced Power Skiving gear cutting technology, which allows components to be skived both internally and externally. Components, such as the internal gears of the planetary gear, which are increasingly being used in future drives, can thus either be machined completely in one clamping operation or, in addition to gear cutting, be machined with upstream or downstream turning, milling or deburring processes. The PITTLER skiving center has also been optimized for fully automated series production: &Uml;via an innovative automation cell, the workspaces of up to two gear cutting centers are automatically supplied with workpieces, which minimizes space and investment requirements compared to robotic loading. In contrast to sequential machining on several machines, it is thus possible to respond economically to varying batch sizes. Translated with DeepL

Highlights:

6-axis – Complete internal and external machining: turning, milling, drilling, skiving, deburring, measuring, sharpening, backing, impact notching

02
Flexible automation: crane or manual loading, robot loading, optional shuttle loading and PITTLER automation cell

03
Automatic tool change through 16-part disk magazine

The PRÄWEMA SynchroFine® XL gear grinding machine is laid out for profile grinding on internal and external gears, on disc and shaft-shaped parts. The machine is laid out in three versions and is suitable for generating gears for components up to Module 32 with an outer diameter of 2,200 mm. Naturally the machine offers an option for hobbing gears up to Module 8.The natural granite machine bed is your guarantee for the highest geometric precision as well as static and dynamic rigidity. The low heat expansion coefficient and high thermal capacity ensures maximum thermal stability. All values for long-term precision, rigidity and thermal stability are better than those achieved e.g. with steel, cast iron or polymer concrete.The motion stand (X1 axis) for the grinding unit also consists of natural granite. The Z1 axis (grinding stroke in axial direction of workpiece) is designed as a wear-resistant linear drive. This allows high feed rates with excellent precision. The pivot axis (B axis) for adjusting the workpiece helix angle is laid out as a wear-free torque motor. The axis can be clamped hydraulically for rough grinding. The stable shift axis (Y axis) allows optimum grinding wheel dressing, correction movements during the grinding process up to incorporation into five-axis grinding for corrections, scanning measurement of the teeth up to use of the grinding operation with revolving worm. The grinding spindle used for hob grinding has an automatic balancing system and structure-borne sound sensors for sparking in.

The modular design of the SynchroForm V machine allows it to be adapted for the production of geared drive components. Set up as a single or twin spindle machine, it excels in series production with extremely profitable cycle times and high-precision machining results. Efficient complete machining in all areas of gearing in soft and hard fine machining can be achieved using the various technology modules. Your advantage: Versatile range of technologies for precise soft and hard fine machining Equipped with either one or two workpiece spindles to match unit requirements Efficient complete gearing machining of drive components
