The requirements placed on calibrating machines in the furniture and panel industry have been extended beyond purely dimensional stability toward a high surface quality. Our machines possess important technical advantages for the calibration of solid lumber panels, solid wood frames, and parquet material.
For high stock removal, a cutter head is available. Even for solid lumber and solid wood panels with a stock removal of up to 4 mm and with a complete charge, the loose fiber chips are removed by the dust extraction system to the extraction channels.
The quality of the cutter block guarantees optimal surface quality for this application. This is achieved by the extracting cut movement caused by the spiral position of the cutting knives. Afterward, it is considerably easier to calibrate and carry out a final sanding with a segmented pressure beam on the same machine.
Torsion-free unit suspension, combined with solid and precise PLC-controlled height adjustment, ensures dimensionally stable parts throughout the entire machine operating life.
A steel roller which, due to its virtually non-measurable wear and precision bearing, achieves a high degree of accuracy even when sanding aggressively.
High motor ratings of up to 75 kW for intensive material removal.
The segmented press-on lip at the in-feed of the calibration roller permits an intensive contact pressure on workpieces with differing thicknesses, even with multi-track feeding.
The cross sanding technology employed for the downstream fine sanding units avoids the washing out effect encountered with softwoods resulting from different annular ring hardness and ensures a flat sanded surface of knots characterized by varying wood hardness.
A greater jump in grit sizes is possible between rollers and cross sanding units due to the aggressive sanding attack of the cross belt.
The electro-pneumatic pressure pad technology precludes a rounding of the edges on calibrated surfaces.
An effective and cost-saving extraction and belt cleaning which can even handle large dust quantities.
