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.
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.
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.

Osborn’s flexible ATB Fascut™ Wheel Brushes feature long trim, flexible Round Crimped Silicon Carbide or Round Ceramic nylon abrasive filaments. Designed with moderate density, this brush is ideal for applications requiring a high degree of conformability. High-quality materials and construction offer the industry’s longest brush life.
Osborn’s aggressive ATB Fascut™ Wheel Brush is designed with short trim, premium nylon filament that is impregnated with abrasive material. Features high density, uniformly distributed Round Crimped Silicon Carbide or Round Ceramic filaments for increased aggression, minimum cycle time, and the industry’s longest brush life.
Versatile Osborn ATB™ Miniature Wheel Brushes are designed for uniform performance even when used on extremely hard materials. Each nylon filament is impregnated with choice of tough abrasive for precision ultra-fine deburring and edge contouring.
Designed to tackle the most demanding of applications, Osborn’s ATB Uni-Lok® Max Density Disc Brushes deliver maximum aggression and reliable, uniform performance. Brushes feature max density, premium quality Round Crimped abrasive nylon filament, making them capable of processing large burrs on stainless steel and hardened alloys without altering the part’s dimension. Expertly designed and tested for minimal cycle time and exceptional brush life.
Osborn’s ATB Uni-Lok® Turbo Disc Brush features Round Crimped abrasive filaments in a unique turbo design to effectively tackle moderate to severe burrs or tasks where conformability is required. When used in dry applications, turbo design draws air into the brush face to run cooler. When used in wet applications, the turbo design allows more coolant to flow within the brushing surface.
Osborn’s ATB Uni-Lok® Quick Change Brushes feature a permanently mounted ¼” shank for quick, convenient attachment to CNC machines, automatic equipment, portable tools, and robotic cells. These small diameter brushes feature premium-quality nylon filament with choice of Round Crimped Silicon Carbide or Round Ceramic abrasive to serve a variety of deburring needs. The unique composite design allows for “touching” of surrounding raised surfaces without harming the part or the brush. Designed and tested for longevity and uniformity.
Constructed with a durable polypropylene base and a dense configuration of strategically located tufts, Osborn ATB Uni-Lok® Tuftmatic™ Disc Brushes offer thorough, uniform performance in both dry and wet applications. Each tuft features high-quality nylon filaments impregnated with Silicon Carbide, and is configured to allow abrasive filaments to flow evenly and consistently over the most intricate flat-faced parts. Compatible with Osborn’s Uni-Lok® adapter system and designed for maximum effectiveness.
Designed with a round trim and densely packed nylon filaments, this Osborn ATB™ Cup Brush offers optimal performance on irregular surfaces. Premium quality nylon filaments filled with Silicon Carbide abrasive to increase effectiveness and brush life.
The industry-best quality and performance of an Osborn ATB™ End Brush combined with a removable plastic bridle offers increased rigidity and aggression. Bridle keeps premium nylon filaments with choice of Silicon Carbide (for cleaning and finishing) or Ceramic (for tough deburring applications) abrasive from flaring for increased aggression.
Osborn ATB™ Miniature End Brushes feature a small diameter for light duty cleaning, deburring, and surface finishing tasks. Brushes are constructed with premium nylon filaments with choice of Aluminum Oxide or Alumina Silicate abrasive.
