Workpiece changing tables

Our 180-degree pendulum workpiece changing tables facilitate simultaneous loading and unloading. This significantly increases machine tool productivity, which in turn reduces the cost per workpiece considerably. In our latest generation of WWE tables, the turning motion is achieved by a servo motor and a backlash-free gearbox. A Hirth coupling guarantees maximum precision. During position changes, a pneumatic cylinder lifts up the face plate by a few millimetres. 


  • High loads and mass inertias
  • Electric drive allows short span-to-span times
  • Cast design for exceptional damping performance
  • Large central opening for media supply
  • No need to connect to NC machines

Drive variants in detail

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 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!

Components in detail

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!

Grey iron housings

Our generously proportioned housings are designed for rigidity and outstanding damping capability to ensure the best possible surface quality for your workpiece.  In dynamic applications, we can optimise the components in house based on FEM calculations. A reduced mass inertia allows for more dynamic axis designs, shortens cycle times and reduces the power consumption of the drives. We always focus on your key requirements.

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.

Application examples


Associated industries: Tool manufacturing

In the TGW series, a fourth axis is added to the tool changing tables. This enables the customer to use clamping plates for three-sided machining, without needing to reclamp the workpiece – reducing retooling times and boosting workpiece precision. In positioning applications, we prefer to deploy worm gear sets; in highly dynamic simultaneous machining applications, we install direct drives. With our optional rotary manifold media supply, we provide an important component for workpiece clamping devices and automated machine tooling applications.


Associated industries: Tool manufacturing

Our workpiece changing table is now equipped with a rotary swivel axis for efficient five-sided workpiece machining. The rigid axial-radial bearings and clamps developed in house provide the strength required even under the most demanding machining conditions. Whether you need one or multiple spindles, we can design a configuration to suit your machine concept and workpieces.


Associated industries: Tool manufacturing

Our top-specification workpiece changing table now incorporates a rotary swivel axis with direct drives. In combination with our high-resolution measurement systems, these highly dynamic drives enable free-form surfaces to be machined on five axes simultaneously, or allow you to perform turning and milling processes. On request, we can deliver our devices pre-assembled, tested and ready to install to minimise on-site installation time. Alternatively, we can supply all of our individually fine-tuned components as a modular kit for maximum flexibility during installation. Whichever option you choose, you can rest assured that all of our components and functions have been designed to work together seamlessly.
