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.

Airway Cloth and Sisal Finger Buff
Woven cloth and sisal buffs are more aggressive than cloth only finger buffs and slightly firmer. These buffs are used for cut down and color on all metals where deep penetration is needed as in lapping or mush buffing in tough to reach locations.
Cloth Meter Buff
Regular folds with cotton cloth, make this large diameter cloth meter buff an aggressive tool with good compound retention and extended life with controlled indexing. Manufactured in large diameters of 28" to 40". Perfect for buffing with low RPM's to achieve maximum surface speed.
Cloth and Sisal Meter Buff
Regular folds with a sandwich of sisal web and cotton cloth, make this large diameter cloth and sisal meter buff an aggressive tool with good compound retention and extended life with controlled indexing. Manufactured in large diameters of 28" to 40". Perfect for buffing with low RPM's to achieve maximum surface speed. Perfect for robotic polishing cells.
Non-Woven Airway Abrasive Buffs
Usually, 2 to 4 layers of non-woven are fixed to a metal clinch ring. The irregular folds offer a versatile satin finishing tool that performs best when minimal pressure is applied, this in turn increases the surface life of the Airflow. This is a highly economical buff.
Interleaf Flap Brush
Medium Density wheels in either Aluminum Oxide Fine or Very Fine grit size is used to relieve black nickel or oxide off brass in an antiquing process. Coated abrasive sheets are positioned between non-woven material for increased flexibility and cutting. Excellent for prep work before staining, sealing, or priming on raw hardwood moldings.
Diamond Cut Contact Wheel
This wheel is used with coated abrasive sanding belt operations as the carrier of abrasive belts and does not touch the product. Made from rubber sections versus cloth makes this contact wheel a durable and cooler wheel to carry belts. Pressed discs are provided to protect sections, maintain structure, providing firmness and keeping the edges from breaking down. The material allows flexibility when needed for contoured edges and parts as they pass across the abrasive belt surface. Used in automated and manual polishing coated abrasive belting applications. The contact wheel is available in multiple configurations and densities.
Airway Cloth Hot Pleated Buff
These buffs have a soft face with some flexibility and are effective tools for contact buffing and provide excellent cut and color options. The pleats are designed to allow for maximum face coverage and flex during mush buffing. The pre-pleating of the cloth causes edge surface to have a random configuration and the plies do not all lay together. This will help eliminate streaking when no oscillation is possible. This buff makes up a softer wheel to reach into recesses and contours.
Airway Cloth Sew Pleated Buff
These buffs have a soft buff face with excellent cushion and are ideal for mush buffing highly complex and contoured parts as they rotate thru the buff. The flat, regular pleats offer an excellent surface for retention of Osborn liquid and solid compounds.
Airway Cloth Seamless Buff
The standard ventilated airway buff with no seams in the form, suitable for almost every step in the polishing process. Many qualities of cloth can be selected for high color polishing on flat or contoured surfaces. The irregular folds fixed to a metal clinch ring form a flexible and economical buff with even wear without excess trimming needed. Buffs can be used individually or mounted on a wide shaft, depending on the equipment available.
Sandshaper Airway Buffs
The coated abrasive flaps of this buff allow for great side to side flexibility along the work face, making them ideal for operations where they are stacked together. This creates an inexpensive flexible finishing buff wheel as wide as you like.
Airway Mill Treated Polycotton Buff
This type of buff is constructed using the highest quality material and is biased to reduce fraying and increase life . The steel center and rigid construction allow for greater pressure and faster cutting speed. Mill treated polycotton buffs offer a heavier, more flexible and resilient cut & color option.
Red Bar High Color Compound
A full range of solid polishing compounds that can be used individually or in combination to achieve a desired result. All compounds are supplied in many variations and sizes for manual and robotic operations. There is no one size fits all, Osborn prides itself on recommending the best, most efficient solution for every application.
