Following global developments and the growth of production in industries such as high-performance motors and plastic containers, the accuracy requirements for mold bases have increased significantly.

In mold base machining, maintaining precise alignment and consistency across large workpieces remains a critical challenge. As the size of the base increases, achieving uniform accuracy over long distances becomes increasingly difficult due to machine behavior, setup variation, and environmental factors. In addition, ensuring consistent finish removal without overcutting or leaving excess material requires highly stable machining conditions and repeatability. Variations in flatness, angle, and positioning can lead to assembly issues and require time-consuming manual adjustments. Furthermore, workpiece setup and measurement processes often add significant time and complexity to production. As a result, improving accuracy while reducing setup time and minimizing manual intervention remains a key challenge in mold base manufacturing.

Yasda’s machining solutions address these challenges by delivering stable, high-precision performance with advanced measurement and control capabilities.

  • High-precision hole pitch accuracy over long strokes
    Achieves pitch accuracy of holes within ±2 μm over a 1 m stroke and ±3 μm over a maximum 3 m stroke (ISO230-2, 2014), enabling highly accurate mold bases with improved service life.
  • Ultra-precise finish milling repeatability
    Provides 1–2 μm level repeatability in finish milling, allowing precise material removal and reducing the need for re-machining after measurement, improving automation efficiency and ROI.
  • Advanced measurement and setup optimization software
    Equipped with the latest software options to measure angle and flatness with high precision, significantly reducing workpiece setup time and improving overall machining efficiency.

Yasda developed the YBM1218V Precision Machine Tool in 1998 to provide the highest finish accuracy for mold base machining. Designed to reduce or eliminate jig grinding and manual polishing processes, it has helped reduce manual finishing work by more than 50%. The first YBM1218V installed at Yasda’s factory in Japan continues to operate today, maintaining machining accuracy within a few microns.
