The surface finish is the first impression set by anyone looking at fine pieces of furniture or, in fact, any wood-based product. This often denotes the level of expertise, care and quality of the product during the manufacturing process.
When creating either a high gloss or semi-gloss finish, the surface needs to be truly flat to allow a mirrored reflection, free from distortion. Also, as veneer slicing technology has advanced, veneer thickness has become less and less, emphasising the importance of both controlled and accurate sanding to protect vulnerable corners and edges. These are areas in which Kundig excels.
The Autumn Open House allowed Kundig to showcase the advantages of its products, from methods of construction to ensure long-term accuracy and longevity, through to choice and application of different sanding aggregates. Several discussions took place covering various topics, including the advantages of individual sanding heads compared to combi units, calibration rollers with steel vs hard rubber coated, fixed sanding beds compared to moving beds and, of course, the advantages of the patented Kundig Oblique sanding versus traditional and ‘super finishing’ heads, which use an inner chevron belt.
Another area which is often both overlooked and misunderstood when it comes to sanding is the correct choice of abrasive for the application. Many machinery manufacturers talk about the capability of a machine with large diameter rollers and big motor HP, etc. However, all sanding machines are limited to the capability of the abrasive. If a sanding belt is overloaded, then it will become consumed very quickly, resulting in high running costs. Kundig manufactures its own abrasives to support its own machinery and is able to offer informed advice on all aspects of sanding.
The all-new Kundig Master was demonstrated sanding both solid wood and veneered panels. This latest version now includes a 200mm working height and an ‘Enormatic’ automatic setting device, which makes the sanding of even the largest panels an easy process, as there is no need for the operator to return to the control panel once this function is activated.
The Kundig Perfect was also shown sanding solid wood, veneer and de nibbing sprayed surfaces. The machine on display was also fitted with a structure brush complete with the new ‘Twinex’ brush to give a textured surface by leaving the hard grain raised.
Also displayed was the complete lineup of Kundig edge sanding machines, from the Uniq with motorised tilting of the abrasive and programmable oscillation to the Uniq-S, complete with an integrated feed system. The Kundig Flash was also shown, which is designed for the denibbing of edges using the same technology employed in the wide belt machines.
