ATU

Rotary tables with worm gear drive

Tables

The ATU rotary tables offer an ideal solution for machining larger workpieces as well as for heavy-duty cutting applications. The rotary tables are available with a vertical or upright rotary axis and a horizontal faceplate. The drive is provided by a backlash-free tensioned worm gear.

As a central bearing concept, we use the YRT design in conjunction with low-torsion, axially acting clamps. To save overall height, the housings of the ATU rotary tables are deliberately kept flat. The cast construction is thick-walled with strong ribs.

On request, we can also project large, free center diameters into the face plates of the rotary indexing tables.

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
