Chamfering is a precision machining operation by means of which a 45° cut is made on the ends or hole of a workpiece in order to eliminate sharp and brittle edges. This operation is one of the most common and widespread and is performed on numerous products from all sectors.
Functions of chamfering
Chamfering is necessary for the production of numerous parts in different sectors. In the manufacture of semi-finished metal products, the presence of the chamfer contributes to the quality of the finished product in several ways, the main ones of which are these:
- Improves quality and safety;
- Increases resistance;
- Facilitates subsequent machining.
Improves quality and safety
The main reason for its popularity is related to its ability to improve workpiece quality by removing all imperfections and burrs formed during previous machining operations. This improves the quality of machining but also makes it less sharp and therefore more safe.
Another reason for choosing to apply a chamfer is related to its ability to give the workpiece important technical characteristics. The elimination of sharp edges gives the workpiece a better elastic effect and better resistance to wear. In fact, the absence of notches provides protection from dents and avoids the concentration of stresses that, in the long run, can cause breaks.
Facilitates subsequent machining
A third reason concerns specific cases where subsequent machining is required. In the case of workpieces that are to be welded, such as the case seen with welded nipples, cutting at 45° gives the surface a more suitable shape to accommodate the welding process, improving and speeding up the process.
Chamfering is a necessary machining operation for the production of mechanical components of all sizes from small fittings such as threaded bushings, pipe nipples, couplings or lugs to large ones such as poles, drive shafts or axles. An efficient solution for the series production of these products is provided by Sinico machines. Over the years of experience we have evolved our machines by integrating beveling into the production cycles.
In the case of simple products, it is inserted for the purpose of finishing the part after the bar cutting phase. On the other hand, for those requiring more machining, beveling, internal or external, is integrated in the most efficient way into the production cycle, optimising the production process.
