A chamfer as a beveled edge of a hole, frequently cut at a 45° incline to the 'normal' surface to breaks a sharp edge. Compare to chamfer made at a 45° angle to the adjacent principal faces, whereas bevel is a sloping edge between two principle faces. 

​A chamfer as a beveled edge of a hole, frequently cut at a 45° incline to the 'normal' surface to breaks a sharp edge. It is also used when performing a deburring operation; running a small cutting tool around the perimeter of a hole (especially in metalworking) to remove any sharp edges or splinters. In this case, the chamfer is non-functional, it is just a result of the deburring operation. Generally the most common form of chamfer is with 45º.

Compare to chamfer made at a 45° angle to the adjacent principal faces, whereas bevel is a sloping edge between two principle faces. A bevel is nothing more then an angled face. It reduces a square edge on an object to a sloping edge, like a chamfer, but encompasses the entire edge. So it looks like an angled edge, rather then a broken corner. 

Thread tapping production is available in our CNC precision machining processing, including CNC milling or CNC turning parts, metal or plastic hardwares, electronic industry, automobile and motorcycle industry, sanitary equipment, electrical and air power tools, plate for outer case, computer parts, secondary machining process in press machine, etc. Actually, thread tapping is widely used in various industrials. It is also equipped with multi-spindle device, interchangeable disk, index disk in order to increase in tapping capacity.

Sandblasing is to dose abrasive into the stream of high preseure compressed air and gets a acceleration in the outflow from the blasting nozzle to against a metal workpiece surface to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface contaminants. It is widely used in different industries, such as: automotive industry, metal-manufacturing industry, foundry, aviation industry, shipbuilding, production of various welded structures, etc.
