Chamfering
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.
What is chamfering and
why it is 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. The result is a chamfer. Or in other words, a space is created to accommodate the individual welding layers through which the workpieces are joined together. The chamfer 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 chamfering?
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 chamfering can be done with sulphur- and iron-free Osborn flap discs. Flap discs with a cambered or straight shape are available. The angle on the workpiece determines the shape of the flap wheel.
Especially if a workpiece made of non-ferrous metal is to be chamfered, we recommend an abrasive cloth with a cooling bond. 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.

Cotton Cloth Airflow Buff
The Industry Standard for Universal Polishing This classic ventilated buff is the versatile "all-rounder" for nearly every stage of the polishing process. Its irregular fold structure, secured by a robust metal clinch ring, creates a flexible and highly economical tool that adapts perfectly to any workpiece contour.
Non-woven Abrasive Airflow Buff
High-efficiency non-woven buff with an irregular fold structure for satin and decorative finishing on complex surfaces. Delivers excellent results with low contact pressure and extended service life.
Lipprox® Convolute Wheel
Non woven abrasive web is wound around a core and specially treated, resulting in a consistent hardness and level of abrasion over the life of the product.
Non-Woven Abrasive Rolls (pads)
Provides a uniform, decorative surface finish without altering dimensions
Flap Wheel - Coated Abrasive
Non-woven flaps are arranged radially around a central core, creating a versatile polishing and finishing tool. The hardness of the wheel is determined by the number of flaps used and can be further increased through impregnation. Available in aluminium oxide or silicon carbide abrasive materials and a wide range of grit sizes, these wheels are suitable for various surface finishing applications.
Lipprite® Flap Wheel
Non-woven abrasive flaps radially bonded to a durable phenolic core, designed for consistent satin finishing and surface preparation.
Cotton Cloth Sisal Airway Buffs
This polishing buff can be manufactured with various combinations of sisal and cotton cloth to meet different application requirements. The construction provides excellent compound retention and a high cutting action, enabling efficient material removal and consistent surface preparation.
Cotton Cloth Sisal Pleated L Buff
L-Buffs made from cotton cloth and sisal are designed for pre-polishing and polishing of complex workpieces where a more aggressive cutting action is required. The folded construction delivers higher abrasive performance than conventional polishing buffs while maintaining excellent surface consistency. Its unique design promotes a cooling air effect, enabling efficient material removal and reducing heat build-up on the workpiece.
Wave Ring Cotton Cloth Buff
Due to their regular wave pattern, these buffs provide a long service life, high polishing performance, and an effective cooling effect during operation. Manufactured with either a metal clinch ring or a metal center ring, they are particularly suitable for finishing pots and pans with polishing compounds, delivering consistent and high-quality surface finishes.
Cotton Cloth L Pleated Buff
L-Buffs are designed for the polishing and finishing of complex workpieces. Their unique folded construction combines excellent performance with a cooling air effect, enabling efficient material processing while reducing heat build-up on the workpiece. The folded structure ensures consistent finishing results, high compound retention, and effective performance across large surface areas.
Mini Sisal Cord Buffs
Mini Sisal Cord Buffs are highly flexible and designed to adapt to contoured and irregularly shaped workpieces. They are particularly suitable for polishing stainless steel and effectively remove grinding marks and surface imperfections from previous processing steps.
Mini Cotton Cloth Buff
Mini Cotton Cloth Brushes are highly flexible and adapt perfectly to the contours of the workpiece. Featuring a slight wave and irregular folding, they provide an effective polishing action.
