Trunnion tables

Trunnion tables come with a horizontal rotation axis. Peiseler's ATC and AWU series are designed with worm gear drives. While the compact and modular ATC series is ideal for small sizes – and also functions as a table – the AWU series is equipped with a robust, rigid housing for high, tilting loads and heavy-duty cutting applications.

ATC models are ideal for face plate diameters below 500 millimetres while the AWU series is primarily designed for larger face plates, although there is some crossover in the processing ranges of the devices.

The AWD series is equipped with a direct drive for a highly dynamic performance and maximum control precision. AWR trunnion tables are fitted with preloaded gear wheel drives for dynamic positioning of even the heaviest loads.

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

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

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.

Active clamp

Our patented spring-preloaded, hydraulically actuated axial active clamp reliably grips the axis in a matter of milliseconds. It is ideal for use as a safety clamp in horizontal axis configurations, and is operated at a release pressure of 120 bar. The material combination is designed to ensure a long service life and to prevent fretting corrosion, minimising maintenance costs and reducing downtime.

Pneumatic clamp

All machine tools provide access to the pneumatic systems. Thanks to our specially developed operating principle, our pneumatic clamps boast friction torques that are virtually identical to those of hydraulic clamps.

Subdevices with 6 bar pneumatic clamping can be used in any application with a compressed air supply, making them the number-one choice for customers looking for an easy and clean retrofit solution.

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.
