Integrated Secondary Processes

After CNC turning, our EDM (Electrical Discharge Machining) and Wire EDM services refine parts with complex geometries or ultra-hard materials:

Wire EDM for Intricate Features

• Applications: Slots, threads, and micro-holes in tungsten carbide or hardened steels.

• Process: Achieves ±0.002mm tolerances using brass wire and deionized water.

• Case Study: Cut 5,000 tungsten carbide bushings with 0.1mm slots for semiconductor manufacturing equipment.

Sinker EDM for Internal Geometries

• Applications: Internal splines, non-circular holes in hardened 4140 steel.

• Process: Uses graphite electrodes to machine shapes without heat distortion.

• Case Study: Produced 2,500 hardened steel gears with helical splines for robotics actuators, reducing post-processing costs by 30%.

Hybrid Workflows

• Step 1: Rough-turn titanium or Inconel parts to near-net shape.

• Step 2: Apply Wire EDM to finalize internal coolant channels or threads.

• Result: Combines speed (turning) and precision (EDM) for high-performance components.
