Non-woven web - SVL tools

The non-woven web or grinding fleece is a three-dimensional structure made of synthetic fibres that are arranged randomly and are offset with abrasive media (abrasive grains). Aluminium oxide or silicon carbides are used as abrasive grains. The abrasive grains are bonded to the fibres with a resin. During manufacturing of the grinding fleece, the resin and the abrasive grains are positioned such that the distribution in the structure is uniform and homogeneous, and as a result the grinding fleece obtains its very good grinding properties that last over the complete service life of the tool that is created from it.

The non-woven web is flexible and yields during use due to the three-dimensional structure of the fabric. During use, there is continuous contact with new grains due to the homogeneous distribution of the abrasive grains. This guarantees a uniform level of removal. The random structure of the grinding fleece also prevents the active surface from clogging up during the treatment.

If grinding fleeces are further processed to make tools, then strips (lamellae) are also cut from the grinding fleece that are arranged in a radial manner around the axis of a waterproof laminated paper tube and glued on. Corresponding rollers and wheels can be manufactured from this basic tool.

If these tools are then further processed, they can also be optimised in terms of their flexibility or in terms of their water and chemical-resistant properties via various measures.

The flexibility can be varied by changing the material density in the tool. The use of impregnations is another option. Impregnations generally cause a further reduction in the flexibility and a simultaneous improvement in water or chemical resistance.


The product properties of SVL tools are defined by the selection of the material (grain and grain size), number of lamellae (density) and impregnation.

If a flexible tool is required, then the number of lamellae is lower than is the case for harder tools. More flexible SVL tools can compensate for slight differences in height of the workpiece being treated.

The higher the number of lamellae is, the harder the tool will be, which will lead to a lower level of flexibility and an increased service life and aggressiveness.

SVL tools are suitable for both dry and wet treatment.
