Tables

Our tables feature vertical rotational axes. Peiseler has designed the ATC and ATU series with worm gear drives. The ATC series features a compact and modular design for small sizes. It can also be used as a trunnion table. The ATU series has large axial and radial roller bearings for high loads and machining forces. Face plate diameters less than 500 mm are the domain of the ATCs, while larger face plates are reserved for the ATUs, although there is some crossover in the processing ranges of the devices.

Our ATD series is equipped with direct drives. It has a high motor torque, and the ATD dyn version offers a high speed and long duty cycle for turning applications. The ATR series has a preloaded gear wheel drive, and the ATHN series is comprised of indexing tables with a non-lifting Hirth coupling.

Drive variants in detail

Direct drive

Direct drives allow highly dynamic and continuous movement and with this, a constant flow of new machining concepts. Peiseler took the lead in this technology as early as 1997 with the development of the world's first subdevice with a direct drive, just as it did with the first two-axis rotary tilt table with a direct drive in 2001. Today, we are in the technologically leading position to offer you direct drives for turning operations in S1 continuous milling. Increasing machine speed while maintaining bearing rigidity at a level that is also suitable for milling enables us to combine turning and milling applications. This allows Peiseler's development engineers to use machining centres more flexibly. Direct drives use very sensitive control technology and place high demands on energy supply.

The benefits for you

  • Highly dynamic, precise control

  • Speed variability

  • Simultaneous machining, turning and grinding all possible

  • Symmetrical design reduces space requirements

  • Low-maintenance

  • Not susceptible to overload and crashes

Hirth couplings

Peiseler designs and produces lifting and non-lifting Hirth couplings for indexing processes. NC operation is not possible with this technology. Hirth couplings transfer very high loads, particularly tangential moments. They have a very high positioning repeatability. In the non-lifting variant, the rotary tables are designed with an axially fixed bearing. With this special design, the face plate remains in position axially during all movement sequences. Designs with a lifting Hirth coupling lift the face plate by a few millimetres for turning.

The benefits for you

  • Various spacings available up to 360 teeth/1°

  • Manufactured in house and can be adapted to any installation space

  • Form-fitting for maximum mechanical positioning precision & repeatability

  • Maximum rigidity in drive train

  • Combined with generously proportioned cast housings for an optimum damping performance

  • All core assemblies from a single source!

Pinion drives

Peiseler offers subdevices with preloaded gear sets with spur or bevel gearing. The available space determines the design; usually a multi-stage solution of one of the two alternatives. Compared to the worm gears, gear drives are more complex due to the multi-stage design. Elimination of backlash is achieved by mechanically or electronically tensioning two drive trains. The high torques, speeds and duty cycles are advantageous. Based on their characteristics, gear drives are classified between worm gears and direct drives.

The benefits for you

  • No cooling required

  • Better dynamics than worm gears, higher torque density than direct drives

  • Combines the technical advantages of worm gears and torque motors

  • Ability to adjust control stability of drive train

  • Backlash-free, so suitable for simultaneous machining

Worm gear drives

Peiseler uses three-piece worm gears, a well-known design developed by Ott. These gears consist of a worm wheel and a two-piece worm, the shank worm and hollow worm. During assembly, we adjust the gear so it is backlash-free. Readjusting the worm during its service life is simple with a commercially available mounting tool. The design advantages are a compact gear ratio, high mechanical precision and the control's excellent regulatory quality. Heat limits the duty cycle.

The benefits for you

  • Simple commissioning/easy installation

  • Easily adjustable worm gear

  • Maximum drive moment and low backlash

  • Self-braking (safety feature)

  • Cost-effective solution for positioning applications

Hirth couplings

Peiseler designs and produces Hirth couplings as a component of subdevices, spindles and as a centring coupling for shaft force transmission. Our product portfolio includes Hirth sets made of two rings for the lifting mode of operation and three rings for the non-lifting mode of operation. High-quality, heat-treated steels allow us to integrate bearing running surfaces or other design elements. Peiseler primarily delivers Hirth couplings according to customer specifications.

Rotary manifolds

We build rotary manifolds for air, water, cooling lubricant or oil up to 250 bar pressure. We have developed low-friction seals in rotary manifolds to meet the demands of the mould-forming industry and high-speed axis applications. We work with our suppliers to develop special lines of seals with an optimum sealing performance. Coated manifold shafts withstand the loads of the dynamic, continuous movements common in free-form surface production.

The benefits for you

  • Developed in house/maximum design flexibility

  • Can be adapted to suit any requirements

  • Nested design available

  • Maximum availability/process reliability

  • Low-maintenance

  • Compatible with a wide range of media

  • All core assemblies from a single source!

Passive clamp

Our highly responsive, patented axial clamp is designed for low distortion. The clamp – which activates with a pressure of 60 bar and is open when de-energised – reduces the span-to-span time. Thanks to its design and targeted force flow, the clamp increases the rigidity and damping capacity of the subdevice, which in turn promotes a longer tool life and protects the surface of the workpieces. The material combination is designed to ensure a long service life, minimise maintenance costs and reduce downtime.

Hydraulic clamp

Our highly responsive, patented axial active clamp is spring-preloaded and is ideal for use as a safety clamp in horizontal axis configurations. The material combination is designed to ensure a long service life, minimise maintenance costs and reduce downtime.

Available sizes

All Peiseler subdevices are designed for a wide range of applications. From workpiece positioning and machining of the smallest components, to handling heavy loads and outsize workpieces, Peiseler offers the optimum solution, with seamless scaling to suit your requirements. We can also adapt our subdevices to meet your individual needs.
