Rotary tilt tables for precise machining operations

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

This redesigned drive train is primarily used in swivel axes in our two-axis rotary tilt tables up to ZASG 400 size. In this innovative concept, the torsion and backlash-free Galaxie® drive is combined with a torque motor, optimising the value for money of your machine.

Ideal for five-axis machining of lightweight structural components. A spring-actuated active clamp secures the axis and ensures that it is brought to a controlled stop in the event of a fault.

The benefits for you

• Reduced heat generation across the entire machine thanks to high level of efficiency

• Reducing the starting torque enables us to use smaller drive components, which means that the control cabinet takes up less space

• The weight reduction of around 26% compared to direct drive axes results in a more dynamic performance when used on a linear axis

• All of this results in a long-term reduction in the total cost of ownership

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

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

• Standard applications use all common axial and radial bearings

• Bearings also designed and produced in house

• In-house parts and purchased parts

• Design and service life calculations for combined ball and cylinder roller bearings as required.

• Our flexibility and many years of expertise enable us to find the right design for your application.

The benefits for you

• Solutions developed in partnership with well-known bearing manufacturers

• Low space requirements

• Cooling concepts and temperature monitoring can be integrated at the bearing location

• Careful selection of components to increase power density and rigidity

• Components optimised for low friction and high speeds

• Selection of the best bearing concept for the process

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.

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.

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.
