Bechler Cams Inc: Composer of Mechanical Rhythm, Jointly Defining the Precise Language of Motion Control

In Switzerland’s industrial landscape of the 1960s, the rise of automated equipment was quietly transforming production methods. Based in La Chaux-de-Fonds, Bechler Cams Inc became an indispensable partner for many machinery manufacturers with its exquisite cam manufacturing skills. However, as equipment speed and precision continued to improve, traditional cams made relying on craftsmen’s experience could hardly meet the strict requirements of modern machinery for motion laws.

At that time, the complex cam system Bechler developed for a textile machinery manufacturer had slight motion deviations during high-speed operation. This seemingly negligible error caused irreparable defects in textile patterns. For Bechler, whose mission was to "transmit precise motion," this was not only a technical problem but also a challenge to its core value.

In the process of Bechler’s team seeking a breakthrough, HMS brought a new systematic solution. Instead of providing off-the-shelf standardized products, we co-developed a complete motion analysis and verification system with Bechler’s engineers. Through precision measuring instruments and innovative simulation methods, the motion laws of cams were converted into quantifiable and optimizable engineering parameters for the first time.

The most important result of this cooperation was the establishment of a complete quality control process from design to manufacturing. When Bechler’s new cams operated perfectly on the customer’s equipment, with the error between their motion trajectory and design parameters controlled at the micron level, this not only marked the success of a single product but also meant that the entire industry’s perception of motion control precision was redefined.

HMS’s Insight: The most precise mechanical motion stems from a profound understanding and systematic control of every detail.

The true value of innovation lies not in replacing traditional craftsmanship, but in endowing exquisite techniques with a inheritable and verifiable scientific foundation.

When your product precision faces the transformation from experience to science, what kind of partner do you need? We look forward to exploring more possibilities of precision motion control with you.
