BÜTFERING SWT 124 MK – planer-sander
The Bütfering SWT 124 MK is a planer-sander combining a cutterblock unit and a combination sanding unit. It planes and sands in one pass and is intended particularly for glued solid wood panels and applications requiring greater stock removal. Working width is 1,100 mm.
This archive treats SWT 124 MK and SWT 124 MC as equivalent designations: K denotes Kombi and C denotes Combi. This designation mapping is based on equivalence confirmed by the archive operator.
Machining and machine configuration
The cutterblock unit uses four-sided reversible knives and permits stock removal of up to 2.5 mm. It is followed by a combination sanding unit with a grooved rubber-covered contact roller, 160 mm in diameter and rated at 65° Shore, plus a pneumatically supported sanding pad. Standard equipment includes automatic workpiece thickness adjustment, continuously variable inverter-controlled feed, pushbuttons and a multifunction display, a wear-free brake and Poly-V drive belts. The working units have independent drives.

Application and classification
This configuration combines planing with subsequent belt sanding. The cutterblock is a planing unit, so the machine has only one sanding belt despite its two working units. Stock removal must be matched to the material and machining task. These figures reflect the historical brochure specification; the equipment of an individual used machine may differ.
