  Slow Wire EDM (Electrical Discharge Machining)

   

  Premium wire EDM systems from AgieCharmilles and Sodick achieve 0.002mm accuracy with surface finish Ra 0.05μm. This technology is critical for machining fine micro-holes down to 0.03mm diameter, narrow slots, and sharp internal corners that milling cannot reach. For thin-walled float components, this precision prevents deformation during ejection and ensures consistent wall thickness throughout production.

   

  Customer Value Translation: For level switches requiring precise sensor mounting holes or float valve stems with tight clearance requirements, this capability ensures every feature meets print dimensions from the very first shot—eliminating costly rework and assembly fit issues.

   

  Sink EDM (Die-Sinking)

   

  Sink EDM capabilities from AgieCharmilles and Makino deliver ±0.002mm accuracy with mirror surface finishes (Ra < 0.1μm). Deep cavities, narrow slits, and complex geometric features are machined with micron-level precision—essential for high-performance sensor parts requiring tight tolerances on internal surfaces.

   

  Precision Grinding

   

  Surface grinding from OKAMOTO and profile grinding from WAIDA achieve ±0.001mm accuracy. This is critical for finishing hardened steel mold components, ensuring perfectly flat parting surfaces and precise slide fits that eliminate flash and maintain dimensional consistency across millions of cycles.

• Large-Gantry CNC Milling

   

  Supports mold bases up to 2,000mm × 1,200mm, enabling large multi-cavity float valve frames in a single mold base—no splitting required—reducing per-part molding cost by 15–25%.
