Precision 45# Steel Fixture Cover Plate: High-Quality Milling Solution for 3C Assembly Tooling

We successfully manufactured a precision 45# steel fixture cover plate for a 3C product assembly line tooling application. This protective and positioning cover plate serves as an integral component of the assembly fixture system, requiring consistent flatness and dimensional accuracy to ensure reliable fixture performance in high-volume production environments.

Project Overview

Key Technical Highlights

• Precision Flatness Control: Achieved flatness ≤0.01mm on critical sealing and mating surfaces through optimized milling strategies and controlled cutting parameters, ensuring consistent fixture closure and positioning accuracy.
• Process Innovation:
  • Multi-Stage Milling Strategy: Roughing, semi-finishing, and precision finishing passes with optimized toolpaths minimize thermal distortion and stress-induced deformation.
  • Low-Stress Fixturing: Custom workholding solutions minimize clamping distortion during machining, preserving geometric integrity across all critical surfaces.
• Surface Quality:
  • Controlled finishing passes deliver Ra≤1.6μm surface finish on all functional surfaces.
  • Burr-free edge preparation ensures clean assembly interfaces and safe handling.

Quality Verification

Each component underwent comprehensive inspection using CMM measurement for flatness (≤0.01mm) and dimensional accuracy (±0.02mm), supplemented by surface roughness verification (Ra≤1.6μm) and visual inspection.
