Grinding, it is the process of removing materials with grinding tools.It belongs to the application of precision machining in machinery manufacturing industry widely.Our BBN own to have all kinds of advanced grinding machines,such as flat grinder,universal grinder,NC optical profile grinding machine ,Jig grinder and so on.


Electric resistance welding ERW refers to a group of welding process such as spot and seam welding that produce coalescence of fay surfaces where heat to form the weld is generated by the electrical resistance of material combined with the time and the force used to hold the materials together during welding.


Planing cutting is using planer tool to do the horizontal relative straight reciprocating motion of the workpiece. It is mainly used for the shape of the components processing. The precision of planing can be reached IT 10-IT8, roughness of surface (Ra) up to 6.3-1.6um.


Rolling - With 18 years rapid development, BBN specialized in the rolling plates. BBN owns advance equipment with German origin, which allows rolling of heavy plates and large diameter cylinders and cones. In addition, we have 2 folding presses with a capacity of up to 500 tonnes, 2 tables with cutting capacity of up to 300 mm for carbon steel, 1 furnace for heat treatment, normalizing) and various light machinery appliances.


The punching technology is a kind of metal processing method. It is established on the basis of metal plastic deformation, to put pressure on the sheets by molds and punching equipment, and to make the sheets generate plastic deformation or separation, thus obtaining punching parts with certain shape, size and performance.


Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances.
