Exakt Fijnmechanika: Excellence in the Finest Details, Jointly Bridging the Gap in Precision Assembly

In the early 1960s, the precision instrument industry in the Netherlands was quietly emerging. Though a young company, Exakt Fijnmechanika in Eindhoven had already demonstrated extraordinary potential in complex optical instrument components. However, a seemingly simple challenge loomed as an insurmountable gap: how to maintain stable assembly precision of metal and glass parts with different coefficients of thermal expansion amid dynamic temperature changes.

At that time, the high-precision measuring instrument Exakt built for an emerging research institute performed flawlessly in the laboratory’s constant temperature environment. But in the customer’s actual use, micron-level displacement deviations occurred due to ambient temperature fluctuations. This subtle deviation was enough to render the instrument’s measurement data scientifically worthless. For Exakt, which regarded precision as its lifeblood, this was not just a technical setback but a test of its professional credibility.

Trapped in repeated unsuccessful debugging, the Exakt team invited HMS engineers. Instead of rushing to offer off-the-shelf solutions, we conducted an in-depth analysis of the entire process from material properties to assembly techniques. We realized the root cause was not insufficient processing precision, but a lack of systematic understanding of "dynamic precision." The core value HMS brought was introducing a brand-new assembly concept based on materials science and thermodynamic analysis — through carefully designed compensating microstructural components and specialized adhesives, actively guiding and offsetting stress changes caused by thermal expansion and contraction.

This cooperation not only solved Exakt’s urgent problem but also helped it establish a design and assembly methodology "for real working conditions." Since then, the product reliability of Exakt Fijnmechanika has achieved a qualitative leap, laying a solid foundation for its future status as the preferred partner of top European research institutions.

HMS’s Insight: The highest level of precision lies not only in static perfection but also in consistent stability under dynamic environments.

A true partner can identify the fundamental crux beneath the surface, transforming the customer’s challenges into opportunities for joint evolution and defining new standards.

When your products face the challenge of moving from the laboratory to the real world, what kind of partner do you need? We look forward to exploring new dimensions of reliability with you.
