Wood is the ideal building material for creating architectural elements with innovative mechanical, insulating and fireproof features, states SCM. One example is sound-absorbing panels, which need to be machined with the most up-to-date technologies and methods to successfully achieve a product of exceptional quality. 

Processes like trimming and sanding, 3D finishing, profiling and grooving machining deserve particular attention. Because of this, an increasing number of companies in the industry need to meet high levels of productivity, while equally guaranteeing absolute machining quality and precision.

Mission impossible? Not for SCM, which, thanks to its decade of experience in designing and developing technological solutions for timber construction, has created a fully integrated line for profiling and sanding three-layer sound-absorbing panels. 

An engineering project to cover its entire production cycle has been chosen, among other things, by German company Lignotrend, one of Europe’s leading players in this sector.

The advantages

Increased productivity, shorter set-up times, greater machining precision and a dramatic improvement in the finishing levels achieved are what SCM says are the advantages that make its engineering solution stand out above the rest. 

The line is controlled by a single piece of supervision software, Maestro Active Watch, which ensures full integration of all the machining phases. This means that, each minute, three standard-size panels are produced, as well as guaranteeing with greater flexibility and simplicity a surface finish that is diverse and highly sought-after.

The automation process and flexibility mark the first stage of the trimming process lengthwise, which is carried out on a Celashi p30, a very precise machine compared to others in the same category, says SCM. Integrated by a Mahros system with roller conveyor to automatically load pieces, it can achieve different-sized transversal cuts (from 3m to 1500 or 700mm), always with the same precision and speed – from 3-5 panels/min.

Once the trimming is completed, the pieces need to be brought to their required thickness. The trimmed panels are transported along the roller conveyor at a speed of 12m/min to an initial compact sanding line consisting of two DMC System machines, to calibrate the upper and lower faces of the panel. Thanks to seven different machining heads, a third DMC System automatic structuring machine completes this stage of the process, carrying out various kinds of finishings on the panel – such as different levels of rustication – with attractive results and design. 

Another connection unit transfers the sanded, calibrated panels to two Celaschi squaring machines – one assigned to transversal profiling, the other to profiling the longitudinal sides – to achieve the required lengths and widths.

Subsequent stages involve the panels being further machined and perfected with surface grooving processing, to increase the sound-absorbing surface, and brushing for the final clean. This is executed by another top-of-the-range DMC System which, thanks to the power and efficiency of its units, provides impressive surface finishing.

Impregnation and manual unloading complete the process, with what SCM describes as “exceptional quality” results.
