Don't care about weight and dimensions - DEMMELER has the right solution!

Exact positioning and flexible processing

Demmeler is a world-leading manufacturer of rotary and rotary/sliding tables. We are a quality leader in this field. Demmeler sets the industry standard with its unique modular system and extremely robust structure as well as the sophisticated drive technology with Duo Drive and positioning accuracy in the µ-range. For large rotary tables, Demmeler counts on a hydrostatic mounting. This makes it possible to develop and produce tables with a length of up to 12,000 mm and a load capacity up to 500 tons. Naturally we also design our rotary tables with sliding axes in the length desired or required for your field of application.

We are also a capable supplier of carousel rotary tables with a broad range of products in this segment. Special options and requirements are coordinated quickly and implemented to perfection. This often results in products that offer a competitive advantage, like our patented swivelling and tilting table for the wind power industry. Here the kinematics developed by Demmeler support tilting by 10°.

Our product range includes swivelling tables, tilting tables, carousel rotary tables and rotary tables with hydrostatic mounting. The rotary table with roller bearing mounting and as a vertical model is new to the product range. We also design and deliver direct drive rotary tables. By request you can get your NC rotary table without a sliding axis or with a W/V-axis. With a controlled NC axis, the rotary table is suitable for path milling. Continuous positioning is possible in any angular position thanks to the rotary axis. A version with a hydrostatic linear axis is offered as well. This gives the rotary table outstanding damping properties and makes it highly resistant to wear.

Since Demmeler develops every rotary table as a modular system according to the building block principle, configuration options are available to you in order to meet your needs. For example, you can get your rotary table with a slideway in the standard version (two linear guide tracks) for a load capacity of up to 250 tons. In the heavy version (four linear guide tracks and centre fixators), the rotary table has an even higher load capacity of up to 500 tons. The machine bed itself is very compact and space saving. It is well protected under the steel cover and driven by a ball screw spindle. All required operating and control elements are easily accessible in an energy centre integrated into the rotary table. The rotary table is easily connected to machine tools thanks to standardised plug-in interfaces.

A process speed of up to 25 metres per minute and a feed force of 50 kilonewton are supported by the rotary table. The traverse paths are 1,000 – 10,000 millimetres and the load capacity of the rotary table is 10-500 tons. We realise longer traverse paths for you individually on request.
