I. Product Overview

This CNC electrode assembly is a dedicated set for electrical discharge machining equipment, made from aluminum alloy tube material processed by a CNC lathe. The cylinder, top positioning pin, and sealing groove are all cut and formed in one operation, ensuring no joints or welds, with excellent concentricity. The outer circumference has a standard sealing groove, which can be matched with an O-ring, effectively preventing the penetration of cutting fluid and dust, protecting the internal discharge electrode. The top pin serves as an accurate guidance and positioning function, ensuring smooth mating of male and female components, thereby guaranteeing the precision of mold processing.
Available for processing in various materials such as aluminum alloy, brass, and stainless steel;外形尺寸、内腔深度、导针规格均可按图样定制；can handle small batch trials and long-term large-scale supply; the entire production process is inspected and controlled according to ISO9001 quality standards.

Two, core highlights of the process and craftsmanship

1. Pipe materials are precision turned and shaped in a single process with high concentricity in structure.
   The whole aluminum tube is processed by fully automatic CNC cutting. The cylinder body, positioning needle, and sealing groove are produced as a single unit, without assembly gaps; male and female connectors fit tightly, and there is no vibration or offset during the discharge machining process.
2. Specialized sealing card slot design, waterproof, dustproof, and leakage-proof
   Precision-machined annular slots, with O-type seals assembled for a firm fit, effectively block the entry of working fluid and impurities into the component, preventing electrode oxidation and short circuit failures, thereby extending the service life of the electrodes.
3. Top guide positioning pin, quick alignment assembly
   Front-end conical locating pin, automatically aligns to the center during insertion, simplifies machine tool fixture adjustment process, effectively reduces assembly and adjustment time in batch processing, and improves production efficiency.
4. Deburring and precision finishing on inner and outer walls, assembly smooth without damaging parts
   The inner cavity, outer diameter, and ports of the tube are smooth with no sharp burrs, ensuring that the insertion and removal assembly process will not scratch the sealing rings or the internal electrode body.
