Grinding Techniques – a Tyrolit company, has launched the Superflex range of non-woven abrasive products, ideal for use with orbital sanders or hand-guided grinding. The range is available in many different shapes, sizes and materials dependent on application and whether used by hand or machine.

Non-woven abrasives are a three-dimensional web of fibres with globules of resin and abrasives embedded into the network of fibres. Typically, the fibres are nylon or another synthetic material. The abrasive types can range from silicon carbide to aluminium oxide or ceramic alumina.

Some of the main benefits and advantages of non-woven abrasives is that they are waterproof, rinsible and resilient due to their open-mesh construction. Used wet or dry, non-woven abrasive products enable the user to achieve a consistent, uniform finish, and conformability to irregular surfaces, with minimal material removal, smearing and discoloration of the workpiece.

The non-woven hand pads and rolls are mainly used for cleaning and processing surfaces using orbital sanders or hand-guided grinding. A wide range of specifications offer the user a variety of surface finishing options. The range extends from coarse specifications for cleaning weld seams through to very-fine polishing applications. A consistent finish with proven longevity is guaranteed thanks to the abrasive grain that is impregnated into the entire fleece of the product and not only located on the surface. Flexibility is also ensured by the abrasive fabric that adapts perfectly to the geometry of the workpiece surface.

Should your application require a portable power tool to achieve your desirable finish more timeously, Grinding Techniques offers numerous non-woven products suitable for a 115mm right angle grinder. This product offering includes but is not limited to Superflex Non-Woven Flap discs, Premium Pre-Polish, Polishing discs and Rough Cleaning discs.

One of the most common challenges when it comes to surface preparation or polishing is getting all the components matched to one another. With Superflex everything you need is available from one source of supply and perfectly matched. With our range of products, you can achieve a mirror finish in only three steps without unwanted burning or discoloration normally caused by overheating.

Superflex Non-Woven Flap discs can be used for various applications in the mining industry on different materials. It removes and blends all rough scratch marks on surfaces. The multi-dimensional flap design reduces clogging and prevents unwanted material discoloration.

To prepare surfaces for polishing, you require a sturdy, high quality product. The Superflex Premium Pre-Polish disc consists of several layers of abrasive fabric ensuring longevity and sturdiness. This allows the disc also to be used for smaller deburring jobs. The ideal operating speed for non-woven abrasive products is typically 60% of the total speed of a 115mm angle grinder but the product has been developed to achieve good results even on non-adjustable speed angle grinders.

Compared to conventional felt discs the Superflex Premium Polish disc is constructed from highly flexible flaps for optimal heat distribution and cool grinding. In doing that the Premium Polish disc avoids undesired discoloration, when used in conjunction with a polishing paste, a perfect mirror finish is achieved on your workpiece. This disc has also specifically been developed to achieve exceptional results even on non-adjustable angle grinders.

When it comes to removing rust, paint, and varnish with the least possible effort or preparing surfaces for welding, soldering, or anodising, the Superflex Rough Cleaning disc constructed from highly porous nylon fibers, and evenly treated with aggressive abrasives, is able to stand up to any challenge. This disc resists loading or smearing and offers guaranteed longevity with an even scratch pattern, and low heat generation with quiet, stress-free working.

Apart from this, Grinding Techniques also offers an extensive range of Convolute and Unitised Wheels manufactured with the latest technology to provide the desired finish combined with a high tear resistance and exceptional longevity. The main applications for these products are deburring, blending and finishing of a variety of materials like metals, plastic and composite materials.

Although Unitised and Convolute wheels are similar types of products, they each have important differences, Unitised being smaller in diameter, usually 150mm or less, making them ideal for use on portable power tools, where Convolute wheels, usually 150mm in diameter, or larger, are ideal for stationary or robotic machines. All products are available in several different densities, grit types and grades.
