Solid Solution for Timber Construction

Due to the nature of timber construction, workpieces usually tend to be very heavy. That's why they are often being sanded by hand. Manual assembly has long been replaced by automated timber processing machinery. So why not make the next step and upgrade the sander? Industry experts agree that in addition to every automated assembly system, a wide belt sander should nowadays be included in order to work efficiently and meet the growing demands regarding surface quality.

Easy Handling

All operations and adjustments are easily attainable - depending on preference, Kündig Machines can be operated fully automatically, with custom automated sanding programmes, or manually, by adjusting all relevant parameters on the go. Built in safety measures eliminate the risk of major accidental operating errors. Kündig sanders are well appreciated for their easy handling.

Powerful Drive for heavy Tasks

The units of our sanding machines can, if useful, be upgraded to 100 kW. An economic, energy saving control system accurately adjusts the output to speed and load needed. Many options like calibration rollers, pneumatic and electronically controlled, segmented pads or brushes are available.

Thanks to the fact that only the upper machine section is moving, the working height stays fixed and the passing height allows for very high work pieces of up to 500 mm (20 inch) to be processed. Additional handling tables that allow easy handling of heavy workpieces with a forklift can be added. To facilitate handling and multiple sanding passes of heavy workpieces, there is a reverse function available which allows to reverse the conveyor direction so that workpieces can be sanded multiple times without lifting them out of the machine.
