Process of manufacturing vacuum tips particularly for vacuum handling systems

摘要

The object of the invention relates to the technical sector of microelectronics. According to the process, one starts off with a hollow stainless steel tube (1) of determined diameter; the tube (1) is shrunk for a certain length (1a) and flattened, the remaining part is flattened to form two opposite flat non close joining faces (1b) and (1c); a slot (1b1) is machined in one of the flattened faces (1b) and a hole (1c1) in the other face (1c); a blade (2) provided with an axial notch (2a) on one of its edges is inserted between the two faces (1b) and (1c); through the hole (1c1) formed in one of the faces, a powder is inserted, designed to carry out microbrazing after heating; the assembly is placed in to a furnace to insure bracing of the blade (2) with the flattened parts and simultaneously filling by microbrazing remaining cavities between the blades and the flattened parts; the ends of the flattened gripping parts are rounded off; the flattened gripping areas are ground.
