Core Advantages
1.Standardized interface for efficient cross-device calibration:Bottom-compatible with EROWA D72 zero-point positioning interface, allowingquick switching between CNC, EDM, WEDM, CMM, and other equipment.
Achieves"one-time clamping, multi-device calibration," significantly improvingequipment precision management efficiency and avoiding repeated clampingerrors.
2.High rigidity and durability for long-term stability and reliability:Bearing steel/hard alloy material, high hardness, wear resistance, andcorrosion resistance, with a lifespan of over 10 years under normal use. Deepcryogenic treatment eliminates internal stress, ensuring the reference columnremains unchanged and accurate over long-term use.
4.Convenient operation, adaptable to all scenarios: One-click positioning andinstallation, no manual alignment required, operation time ≤10 seconds. Thecylindrical reference surface is compatible with various probes (trigger type /scanning type) to meet different measurement needs.
