Metal chamfering refers to the process of adding an angle at the corner or edge of a part, or reducing a formed 90 degree edge to a lesser degree. Purposes for this type of operation include eliminating sharp or rough edges, providing mating surfaces for joints, and creating bladed edges. This type of operation is also known as beveling and is often created at a 45 degree angle, particularly when the surfaces are at right angles to each other. By contrast, a fillet is the rounding of an internal edge while a radius is the rounding of an external corner.
Chamfers can be either external or internal to an edge. Internal chamfers create strength in the part by forming a natural brace to the angle and providing more material at the point of stress. This type of design feature is often used to increase rigidity of the part and reduce the impact of stress and corrosion, thereby increasing the lifespan of the product.
Metal chamfering can also be used to create design features that are critical to final assembly forming a lead in for the part easing mate-ability. Chamfered angles provide more surface contact for mated joints, as well as drive surfaces for interlocking components.
Accurate Forming provides metal chamfering capabilities that are performed as part of the deep drawn metal stamping process. Using additional dies and surfaces, chamfers can be added to the part design at almost any location simply, efficiently, and at low cost.
By comparison, chamfering processes such as milling or grinding often add secondary steps and increase operator interaction which reduces thru-put and increases the cost per part.
The capability of the deep drawn metal stamping process used by Accurate Forming to create various design geometries provides the customer with a service that is flexible, fast, and always an excellent value.
