Unlike classic sawmill plants, carpenters using CNC-operated trimming machines process timber precisely according to the specifications of an architect or structural engineer. These precisely manufactured components can then be used to construct buildings with complex designs using log or timber-frame techniques and roof structures, too. The first plants were developed in 1963 but were still mechanically controlled. The first properly computer-controlled trimming machine arrived in 1984, when Hans Hundegger Maschinenbau GmbH launched the "P8". Since then, Hundegger has grown in size to become Hans Hundegger AG, but it is still very much at the forefront when it comes to integrating the benefits of Industry 4.0 digitalization into actual products. The company is at LIGNA 2017 in Hannover to show just how far it has got with networked production and is showcasing, among other things, the TURBO-Drive cutting machine and its new touchscreen operating concept.
Besides cutting, the TURBO-Drive can also perform drilling and milling work and make markings of all types. The heart of the machine is the flexible saw unit for any angle and inclined cuts. With the 5-axis saw unit, which can be swiveled around 360° and tilted around 90° at the same time, any kind of chop cuts, mitre cuts, Jack rafter cuts, birdsmouths, ridge laps, laps for fascia board and scarf joints etc. can be produced quickly, precisely and in a high surface quality. Unlike solutions that use an undertable mitre saw, the saw blade and axis on the TURBO-Drive cutting machine can move under the supporting height of the workpiece and thus process even horizontal cuts in any angle and any required thicknesses. The compact machine is also encapsulated to prevent dust ingress and noise emission and can be mounted on an even concrete floor without requiring any construction measures.
