Rotary table

Rotary tables are used both in the machining in machine tools as well as in the non-cutting automation. Rotary tables are called depending on the design and rotary tables, rotary tables, indexing tables or dividing heads.

Rotary tables vary according to use both in the designs as well as in the accuracy and rigidity. In the machining of the requirements for the accuracy and rigidity are higher than in the non-cutting area. In automation shortest switching times are required.

Use

Machining

A turntable is part of a machine tool, to be clamped on the workpieces to be processed.

The turntable has a vertical or horizontal axis of rotation often and by which the rotation or indexing table can be rotated with the clamped workpiece to perform machining operations at different positions or on a rotating workpiece.

There are machine tools with continuously rotating turntables, such as vertical lathes, gear shaping and gear hobbing machines.

In other machines, an NC rotary table is controlled and freely programmable clocked, such as slot machines, milling machines, grinding or machining centers. Depending on the application case as drives servo motors with gear backlash adjustment or direct drives with torque motors.

In rotary transfer machines rotary indexing tables with fixed pitch ( for example, 8x45 ° ) are used. The rotary table is transported in the rotary indexing machine the workpieces from processing station to processing station.

Manual indexing units can also be retrofitted on a machine.

Automation

In assembly machines, welding machines, screen printing and pad printing equipment form rotary indexing table with cam drive often the heart of a system. The rotary indexing table transported here on an additional switching plate workpieces from station to station.

Other uses

Addition to the classic cases rotary tables are used to transport any parts. Thus, the 18 -ton and 9 m high statue of Imperia turns to the example in the harbor of Constance on a rotary table.
