Comparison between Tokyo Seimitsu and Coord 3

While both Tokyo Seimitsu and Coord 3 manufacture high-quality coordinate measuring machines, their design philosophies and market focuses differ significantly. Tokyo Seimitsu emphasizes precision and environmental control, making its machines ideal for semiconductor, aerospace, and medical industries where ultra-tight tolerances and traceability are required. Coord 3, on the other hand, provides more adaptable solutions for varied industrial applications, from automotive to heavy engineering.

In terms of precision, Tokyo Seimitsu models like the ZEISS XENOS offer superior accuracy, often below the sub-micron level, coupled with vibration isolation and thermal control. Coord 3 machines are slightly less precise but compensate with flexibility and scalability, such as the MCT PLUS’s ability to handle very large parts.

Sensor compatibility also varies. Coord 3 supports a broad range of tactile and optical sensors, integrating seamlessly with automation and PC-DMIS environments. Tokyo Seimitsu, while primarily focused on Zeiss’s ecosystem, delivers deeper integration and consistency in scanning applications due to its close alignment with CALYPSO software and Zeiss probes.

Software-wise, Tokyo Seimitsu relies on CALYPSO, known for structured programming and parametric inspection strategies. Coord 3’s use of PC-DMIS provides a more familiar interface for users in globally distributed manufacturing environments, supporting advanced automation and CAD-based inspection routines.

Structurally, Tokyo Seimitsu CMMs are often built on granite bases with air bearings and are suited for cleanrooms or lab-based measurement, ensuring long-term stability. Coord 3 offers more rugged machines that can handle the thermal and mechanical stresses of a production environment without sacrificing measurement integrity.

Regarding service and support, Tokyo Seimitsu offers exceptional localized service in Japan and parts of Asia, providing quick response times and technical depth. Coord 3, leveraging its global reach and partnerships, offers widespread service and integration options for multinational operations.

Overall, Tokyo Seimitsu shines in environments demanding utmost precision and environmental control, while Coord 3 excels in flexibility, scalability, and shop-floor compatibility. The right choice depends on your production context, measurement needs, and operational footprint.

Ideal Users for Each Brand

Tokyo Seimitsu is best suited for users requiring sub-micron precision in cleanroom or laboratory environments—such as manufacturers in the semiconductor, medical, or aerospace sectors. Their systems provide unmatched stability and integration with Zeiss technologies.

Coord 3 is ideal for manufacturers seeking flexibility, scalability, and compatibility with PC-DMIS environments—particularly in automotive, general manufacturing, or large-part inspection where rugged design and operational versatility are important.

Conclusion

Both Tokyo Seimitsu and Coord 3 offer powerful solutions in the CMM market, each catering to different priorities. Tokyo Seimitsu stands out in ultra-precise, controlled environments, while Coord 3 delivers scalable, versatile systems ready for a variety of industrial challenges. By understanding their core strengths, businesses can make informed decisions to enhance their quality control processes and production efficiency.
