LEUCO introduces new extractor hood for silent hogging. The new noise absorbing double hogger hood is more cleaner and supports quieter hogging. The new extractor hood from LEUCO is perfect for double hogging adjusts automatically to the panel thickness. Efficiency increases and the equipment operates more cleanly and quietly. In addition, optimised extraction increases manufacturing quality.
The new hood from LEUCO is intended for use on double end tenoners as well as on large edge banding machines with a double hogger.On such industrial machines, it increases the efficiency of chip capture to a new level. The main reason for this is anchoring of the top hood half to the upper pressure beam, since this varies with a change in workpiece thickness. In this way, the hood always adjusts to the right height in relation to the panel thickness. The result is a constant, narrow gap – ideally about 2 mm between the hood and workpiece – and thus to very efficient extraction.
Extractor Hood responds to change in panel thickness
In contrast, common extractor hoods are set permanently to the greatest panel thickness. As a result, the gap width varies between a few millimeters and several centimeters. This variation has conse-quences, since the extraction output drops due to the usually unnec-essarily wide gap, which causes the tool system to become dirty. This makes regular cleaning necessary.Thanks to the consistently narrow gap and resulting maximum effi-ciency of the double hogger hood from LEUCO, the equipment re-mains much cleaner and needs cleaning less frequently.
The two-piece design of the extractor also contributes to reduced chip discharge from this hood: Both the upper and lower housing halves have their own suction connection. They are placed so that the stream of chips generated by the hoggers is directed exactly into the suction openings. As a result, most of the chips are conveyed directly into the extraction system, interfering air flows and deposits in the hood housing are minimised. This reduces double hogging considerably – resulting in higher surface quality and longer tool lives.
Hood housing absorbs operating noise
Because of the tight fit around the processing area, the operating noise of the machine is less pronounced. The sandwich construction of the housing also helps: It consists of two sheet-metal shells with insulating material.This reduces the noise level better than the usual single sheet-metal shell. Combined, these improvements provide a damping factor of 2 to 3 dB, a noise reduction that can be heard clearly.
As a further benefit, the hood contributes to energy savings. Thanks to the narrower gap in the double hogger hood, the hood and hogger form an almost fully enclosed system. This increases efficiency and the hood can contribute to optimization of the energy needs of the extraction system.
