If molybdenum wire installation is too loose, the molybdenum wire shake badly, not only cause broken wires, and because of molybdenum wire jitter directly affects the surface roughness. But molybdenum wire can not be installed too tight, too tight internal stress increases, can also cause broken wires, so molybdenum wire during the cutting process, which should be appropriate to the degree of tightness, the newly installed molybdenum wire, the first tight silk reprocessing, not too much force when tightening wire.
Molybdenum wire in the processing period of time, due to its tensile and loose. When the elongation is large, will exacerbate molybdenum wire molybdenum wire vibration or appear to overlap in the wire cylinder reservoir. So go wire instability caused by broken wires. Should always check the tightness of molybdenum wire, if there is slack, a timely taut.
Molybdenum wire installation. According to the provisions of molybdenum wire wound toward the wire tube in the reservoir, while the fixed ends. Around the wire, the ends of each wire cylinder reservoir generally remain 10mm, around the middle of nonoverlapping full width of not less than half the length of wire cylinder reservoir to avoid leaving parts motor commutation frequently accelerated damage, but also to prevent frequent participation in cutting molybdenum wire the broken wire.
Machine molybdenum wire cited references have blocked silk rods, wire rod block is made of two rubies guide column, unlike the guide pulley block wire rod rolling motion as to make them directly in contact with the molybdenum wire for sliding friction. So wear out quickly, using molybdenum wire in contact with the cylinder near where it will form a groove, must be checked and make flips and replaced, otherwise there will be folding wire broken wire.
