Since 1964, Yasda has specialized in machining high-precision components for machine tools and industrial equipment, establishing a long-standing reputation in ultra-precision manufacturing.

In precision parts machining, achieving consistent accuracy across complex geometries remains a fundamental challenge. Many components require both turning and milling with tight concentricity and positional accuracy, which are difficult to maintain across multiple setups. Frequent workpiece changes can introduce positioning variation and increase adjustment time. Maintaining stable accuracy during high-speed machining further complicates production, especially when balancing productivity and precision. As a result, ensuring repeatable performance while minimizing rework and supporting efficient production remains a key concern.

Yasda’s machining solutions address these challenges by enabling highly stable, precise, and repeatable performance across demanding precision part applications.

  • High-precision turn boring capability
    Yasda’s in-house designed rotary table enables turn boring with concentricity below 10 μm, delivering exceptional accuracy in combined turning and milling operations.
  • Outstanding repeatability in pallet change systems
    Yasda’s original curvic coupling pallet chucking system achieves repeatability within a few microns, significantly reducing the need for in-machine offset measurement and supporting stable automation with PLS and FMS.
  • High-power and high-accuracy linear motion system
    Twin ball screws on linear axes provide high-speed motion and increased cutting power while maintaining excellent positioning accuracy.

Yasda’s advantage in ultra-precision machining lies in its focus on long-term stability rather than short-term peak performance. Today, Yasda’s reliability is widely recognized, with approximately 70–80% of Japanese machine tool builders relying on Yasda machines for their own precision manufacturing. Particularly, the YBM horizontal series machines (7T, 8T, 10T, 15T, 7Ti, 8T-TT, 10T-TT) have been a great aid to our precision parts customers.
