FLEXIBILITY IS THE MAIN STRENGTH

FEATURES OF THE HAND-HELD TYPES AND WITH AN L-SHAPE

Due to its specific function, you can regard the edge sanding machine as a special type of parquet sander. The name says it all: This is a machine which is used for sanding edges. This makes it different from other floor sanders, which are used to sand extensive surfaces of a wooden floor. Those floor sanders are usually big, sturdy, and hardly flexible at all, unlike the edge sander.

Edge sanders for professional use can be divided into two types. The first is that which you hold in the hand and the other is that in a sort of L-shape. You use the latter to sand easily accessible places, whilst the hand-held tool is ideal for corners and skirting boards.

L-shape version

We start with the L-shape version, and to find out about the practical possibilities we ask the advice of a specialist, in this case Pallmann. With this type of edge sander you notice that the motor and the drive of the machine are integrated into the upright section. A typical L-shape machine has a motor which is supported by wheels and a weight of about 16kg. The sanding disc is integrated at the end of the horizontal section. This sanding disc is driven by the motor and connected by a V-belt. The motor causes the sanding disc to rotate at high speed. To make the machine suitable for wooden floors up to the skirting board and under the heating, it is fitted with a protruding front. These machines are used with paper dust bags, an air recycler, or with a fine dust filter. This means that it absorbs most of the sanding dust which is sucked up.

If we look at what Pallmann has to offer, we see the Gecko Star 2.0, which is characterised by comfortable and powerful sanding. We notice with this machine a high capacity (1500 watts, whilst other electro-motors generally have 1250 watts), with 3300 revolutions per minute (sanding disc 178) or 3800 (sanding disc 150).

In addition, manufacturers pay attention to a balanced weight so that it is possible to exert maximum sanding pressure. Moreover, we also see ergonomic shaped handles, wire clamps for the vacuum cleaning tube, a simple setting of the Wheel position, and attention to a balanced weight to facilitate comfortable sanding. Manufacturers have also considered maximum illumination of the area to be sanded using LED technology. Appropriately, this device is fitted with an adapter for a vacuum cleaner so that it is virtually possible to sand dust-free, and we’ve outlined the importance of that in a previous edition. The delivery

includes two zirconium sanding discs of 150/178mm (K40 and K80) and also a short front section is available for sanding under stairs and along edges.

Manually operated edge sander

And so, we move to the manually operated edge sander. Since this machine has to combine strength and convenience, it needs a number of specific assets for perfect sanding along edges and in corners. At Pallmann they refer in this context to the Gecko Flex, which even has a revolutions setting and weighs 4.5kg. Obviously, this Flex is small and compact (work width 180mm) and here, too, makers have paid a lot of attention to dust extraction (you can sand virtually dust-free). The handle, too, has been made more efficient and the Flex has adjustable brushes. The sandpaper which is supplied is: 2x zirconium 178mm, 10-hole (K40 and K80). Here, too, the capacity is 1500 watts. The aim of this machine is also obvious: no corner should be out of reach, but there always has to be an excellent sanding result.

Bona

Bona has a wide assortment of sanding machines for parquet floors, ranging from belt sanders and single-disc sanders to edge sanders. This latter category includes the Bona Edge UX, the latest edge sander in the range. This is an extremely powerful and easily manoeuvrable edge sander with new flexibility and safety features.
