Beveling
If two workpieces are to be welded together, the edge of the workpieces must first be broken by a beveled surface. This is done by machining. The result is a chamfer, also known as a bevel.
What is beveling and
why is it important?
If two workpieces are to be welded together, the edge of the workpieces must first be broken by a beveled surface. This is done by machining. Or in other words, a space is created to accommodate the individual welding layers through which the workpieces are joined together. The bevel can have different shapes. The V-joint, the double V-joint, and the Y-joint are the most common shapes.
Which tool is used for beveling?
The position of the weld, the material of the workpiece, and the types of drives available - the choice of the right tool depends on various factors.
If an angle grinder is available, the beveling can be done with sulfur- and iron-free Osborn flap discs. Flap discs with a conical or straight shape are available. The angle on the workpiece determines the shape of the flap wheel.
If a workpiece made of non-ferrous metal is to be beveled, we recommend an abrasive cloth with a cooling bond as it reduces blue tarnish.

If a straight grinder or air grinder is available, chamfering can be done with carbide burrs. The milling head is made of tungsten carbide-cobalt, the shank of tool steel. Different head shapes and toothings ensure that there is the right solution for every application.
For chamfering, burrs with cross serration (Z6) are the best choice. It ensures high stock removal in a short time. If the surface quality is important, a single tooth (Z3) is recommended. In the shipyard sector, the special shipyard toothing is often used. Compared to the Z6 toothing, it has a 30% higher material removal rate.

Conventional Sisal and Cloth/Sisal Buff
Full disc sisal buffs are used for cut down operations of ferrous and non-ferrous metals. They are constructed from top quality sisal, sewn and treated for added cut and life. Cloth/Sisal conventional buffs alternate cloth and sisal ply to create the desired firmness of the buff. The use of the cloth in the buff adds value in compound retention and softens the buff for contoured parts. The combination of cloth and sisal provides cutting action and high color on steel and aluminum parts.
Abrasive Mechanical Flap Wheels
Tightly packed coated abrasive flaps arranged around a mechanical core, make an effective, durable, and versatile polishing tool. Round parts, tubes, pots & pans or even the sole of an iron benefit from this product, with its long life and ability to continually reproduce the same surface when compared to coated abrasive belts. Great for wide face width applications.
Epoxy Flap Wheels
Coated abrasive sheets are arranged in an epoxy bonded core, making an evenly distributed and quieter efficient polishing tool. This versatile wheel is available in multiple grit types and sizes and can be adapted to fit the application. Round parts, flat parts, edges and contours benefit from this product with its ability to continually produce consistent and repeatable results. Effective for applications with narrow face widths.
Conventional Non-Woven Abrasive Disc
Non-woven wheels ideal for cleaning and finishing parts when using portable tools to get down into an area such as a rotary polisher and high speed grinders or stacked together on a shaft where flexibility is required by the operation
Non-Woven Flap Brush
Flexible, conformable wheels that apply uniform satin finishes. The density is dictated by how many flaps are wound around the core, therefore, a high-density for the firm face when working on a flat surface and a medium density for a softer, flexible face when the part is irregular in shape.
Flex Brush
An open mesh construction makes them ideal for applying finishes. Blending Stainless Steel surfaces to a #4 RMS finish is one the most common applicaitons
Garnet Abrasive Wheel
The Garnet Abrasive Wheel is a convolute wheel built by winding layers of a non-woven abrasive around a round core. The abrasive material is created by extruding fiber strands, resin and garnet mineral. With the softer organic minerals, garnet is a good match for woodworking applications, because it produces finer finishes than synthetic minerals. Ideal for the removal of mill/knife marks and chatter. Operating pressure and speeds are low to prevent burning.
Airway Bias Sisal Buff (BS)
A compact buff, purely made of sisal web. It is a hard, aggressive tool. Sisal is a natural material, perfect for the polishing process due its excellent compound retention properties.
Airway Open Double Cloth Bias Sisal (ODCBS)
A flexible and economical cutting tool with irregular folds of sandwiched sisal and cotton cloth quilted together. The quilting of the cloth and sisal provides flexibility in the buffing of contoured parts, and enables the buff to effectively hold compound. These buffs can produce an aggressive cut or color finish and adapt well to any surface.
Airway Open Bias Sisal Buff (OBS)
A flexible and economical cutting tool with irregular folds of sandwiched sisal. These buffs offer a heavy cutting action with the flexibility to use on flat or contoured surfaces.
Airway Cloth and Sisal Wavering Buff
The combination for dense sisal web and cotton cloth, folded in regular waves, results in a very hard cutting buff, ideal for removing oxidation or other first steps in the polishing process. A very useful tool if there is little or no oscillation.
Airway Polycotton Buff
Similar to the standard ventilated buffs this buff is flexible and versatile. This type of buff is constructed using the highest quality polycottons and is biased to reduce fraying and increase life. Various qualities of gray cloth can be selected depending on the results required. The irregular folds fixed to a metal clinch ring form a dense and economical buff for coloring.
