Precision D2 Tool Steel Fixture Component: WEDM + Milling Solution for 32-Slot 3C Assembly Fixtures

We successfully manufactured a precision D2 tool steel fixture component featuring 32 precision wire-cut slots for a 3C product assembly line application. This high-wear fixture component demands exceptional dimensional accuracy and wear resistance to maintain positioning consistency across millions of assembly cycles in consumer electronics production.

Project Overview

Key Technical Highlights

• 32-Slot Precision machining: Successfully machined 32 precision slots using wire EDM (WEDM) technology, achieving ±0.015mm slot positioning accuracy across the entire component for consistent assembly line performance.
• Process Innovation:
  • WEDM Optimization: Optimized wire EDM parameters ensure consistent slot dimensions, surface finish, and minimal recast layer for extended fixture life.
  • Pre-Machining Preparation: CNC milling performed prior to heat treatment establishes reference surfaces and removes bulk material, reducing WEDM cycle time.
• Material Performance:
  • Precision heat treatment achieves HRC 58-62 hardness for exceptional wear resistance in high-cycle assembly applications.
  • D2 tool steel provides superior abrasion resistance and dimensional stability under repeated assembly loads.

Quality Verification

Each component underwent comprehensive inspection using CMM measurement for slot positioning accuracy (±0.015mm), complemented by hardness testing to verify HRC 58-62 and visual inspection for wire EDM surface integrity.
