Precision at the Lowest Torque Levels: Setting New Standards for Assembly and Quality Assurance in the Watch Industry
In the watchmaking industry, even the smallest torques determine functionality, quality, and reproducibility. This is precisely where the μTDH low-torque screwdriving system comes in: It operates at torques up to 8 Ncm while providing full angular control. For assembly and quality control managers, the system creates the conditions necessary to carry out sensitive screwdriving processes reliably, traceably, and with full documentation.
The sensor-controlled and monitored screwdriving system is specifically designed for applications with the highest precision requirements. A key USP is the unique static torque sensor, which enables highly precise measurement of even the smallest torque values. Combined with a high measurement accuracy of 3%, the system is therefore suitable not only for series production but also for analysis and measurement tasks in quality assurance.
For practical use in watch manufacturing, the handheld μTDH offers additional key advantages: A replaceable vacuum head and blade holder ensure high flexibility when working with different screw types and applications. The flexible hose connection with vacuum suction through the handpiece enables particularly comfortable picking and precise placement of the smallest screws. This simplifies handling, improves ergonomics, and simultaneously increases process reliability in demanding assembly environments.
A key advantage for quality control is seamless data collection. All bolting data, including graphs, is documented using the intuitive nquirer-TD parameterization software. Interfaces also enable integration with customer-specific, higher-level systems. This ensures end-to-end traceability of all relevant process data.
For applications in automated assembly processes, the μTDS series of built-in spindles is also available. Designed for high fastening cycles and maximum service life, they bring the system’s precision to industrial automation.
Whether handheld or automated, the μTDH and μTDS set new standards for precise screwdriving in the ultra-low torque range and offer the watch industry clear advantages in terms of assembly quality, process control, and documented quality assurance.
