Currently, these processes are typically performed on different specialized equipment; for example, milling is done on one machine, while engraving is done on another. This decentralized processing model has several drawbacks: First, the workpiece needs to be transferred, positioned, and clamped between different machines, resulting in low production efficiency and high labor intensity for operators; second, multiple clamping inevitably introduces positioning errors, affecting the processing accuracy and consistency of the product, leading to a high scrap rate; finally, it requires the purchase and maintenance of multiple machines, resulting in a large footprint and high overall costs.

[0016] This utility model has the following positive effects: (1) By integrating the milling cutter mechanism, through hole chamfering mechanism, milling plane mechanism and engraving mechanism into an XY axis servo slide, and working in coordination with the spindle clamping mechanism, this utility model realizes the continuous and automated completion of multiple processing steps of the conductive nozzle on one machine. This effectively solves the problems of dispersed processes, low efficiency and poor precision in the prior art, significantly improves production efficiency, reduces equipment footprint and manual intervention, and ensures the consistency of product processing.

[0017] (2) The milling mechanism in this utility model uses a first milling cutter and a second milling cutter arranged opposite each other, which can simultaneously mill the upper and lower planes of the conductive nozzle.
