This wire-cutting water nozzle features an integrated, custom-designed 3D-printed structure, optimized for smooth wire threading and superior water-spraying performance. The nozzle inlet incorporates a gradual flared expansion design, with a smooth taper from the outer edge to the inner core, creating a rounded, streamlined flow surface that eliminates sharp edges and steps.

The intermediate transition section employs a curved chamfer to prevent abrasion of the molybdenum wire; meanwhile, the internal water outlet channel is straight and unobstructed, ensuring stable water pressure and minimizing the risk of residue buildup and blockage. The overall mounting dimensions are precisely matched to the machine, allowing the molybdenum wire to be smoothly guided during threading, completely eliminating wire snagging and jamming issues and significantly improving machining efficiency.
