Following the recent growth of industries—such as medical, IT, automotive, connectors, optical, plastic injection—mold forms are becoming smaller and much more precise.

Micro mold machining presents growing challenges as components become more intricate, making it difficult to achieve both superior surface quality and precise dimensional accuracy while maintaining consistency. In addition, machining high-hardness materials often requires multiple processes, leading to variability between stages and overall instability in quality. The use of separate machines for each process further introduces risks such as setup errors and positional misalignment, which can compromise accuracy. As a result, maintaining high precision while ensuring consistent, repeatable quality in production remains a significant challenge.

Yasda’s machine structure is designed for long-term stability, enabling consistent accuracy even after years of operation.

  • Ultra-precision surface and pitch accuracy
    Achieves surface finishes below Ra 10 nm and pitch accuracy within ±1 μm, ensuring exceptional consistency across complex micro-scale geometries.
  • Hard milling of high-hardness materials
    Capable of directly machining materials hardened to 60 HRC or higher, significantly reducing reliance on EDM and manual polishing while improving overall process efficiency.
  • Integrated jig grinding and graphite milling capability
    Supports oscillation grinding (jig grinding) within the machining center, along with wet graphite milling, enabling multiple high-precision processes to be completed in a single setup.

These technologies are implemented in Yasda’s YMC430 Micro Machining Center, developed specifically for ultra-precision micro milling, as well as the larger YMC650, which expands machining capability for larger molds and complex multi-axis applications.
