Carbide burrs, also referred to as carbide rotary burrs are used with high-speed electric mills or die grinders to process metal, wood, plastics, etc. Carbide rotary burrs are trusted in machinery, automobile, shipbuilding, chemical industry, craft carving, and other industries. Choosing the proper carbide burr on your project is important. There are lots of strategies to selecting a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The form with the carbide rotary burr ought to be based on the contour from the workpiece. When processing the inner arc surface, a semi-circular burr or round burr (small diameter workpiece) ought to be used; when processing the inner corner surface, triangular burrs needs to be selected; when processing the interior right angle surface, a flat burr and square burr may be selected. Once the flat burr can be used to cut the inner right angle surface, it is vital to generate a narrow surface (smooth edge) without teeth all-around one of the inner right angle surfaces, in an attempt to avoid damaging the best angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth ought to be determined in accordance with the allowance size the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr is acceptable for machining workpieces with large allowance, low dimensional accuracy, large form and position tolerance, large surface roughness value, and soft material; otherwise, fine-tooth carbide burr ought to be selected. When used, it ought to be chosen as outlined by machining allowance, dimensional accuracy, and surface roughness essential for workpiece.
Sizes of carbide burrs
The size and specification of cemented carbide rotary burr should be selected according to the size of the workpiece and machining allowance. When the machining dimension is large and the allowance is big, cemented carbide rotary burr using a large size should be selected, or possibly a tungsten carbide rotary burr using a small size must be selected instead.
