The core of competitive edge in precision manufacturing lies in imperceptible micrometer‑scale deviations. Inadequate control of dimensional accuracy can easily lead to assembly failures and mass scrap; a stable, reliable length‑measurement system is an indispensable source of confidence in the quality‑inspection process.

The Yechi Instrument fully automatic high-precision length measuring machine, based on the Abbe measurement principle and equipped with a high‑accuracy grating measurement system, delivers stable, intelligent, and versatile metrological performance, making it the preferred choice for metrology laboratories and precision manufacturing facilities.

1 Powerful functionality that meets a wide range of measurement needs.

The equipment supports fully automated internal and external dimension inspection and can calibrate a wide range of gauges, including gauge blocks, smooth ring plug gauges, thread gauges, calipers, and master bars. It is also compatible with precision workpieces such as shafts, gears, and bearings for dimensional measurement. The entire process operates in an automated mode: automatic positioning, continuous data acquisition, real-time computation, and automatic generation of standardized inspection reports upon completion. All data are comprehensively retained throughout the process, meeting enterprise quality traceability requirements and ISO‑compliant audit standards.

• Measurement accuracy is stable and reliable. A monolithic natural marble base offers excellent resistance to deformation and superior shock absorption; paired with precision linear guides, it enables absolute measurement throughout the entire travel range, minimizing transmission errors introduced by gauge block calibration and accurately capturing dimensional changes at the micrometer level.
• Fully automated operation, reducing human interference. It eliminates the challenges of manual, repetitive alignment and hand‑reading, effectively mitigating data bias caused by variations in operator skill and significantly boosting batch‑inspection efficiency.
• The force measurement is continuously adjustable, accommodating a wide variety of workpieces. A controllable force‑measurement system can both measure hard standard gauges and protect thin‑walled, easily deformed workpieces, preventing the probe from crushing or damaging the sample.
• Simple to operate, with a low learning curve. Visualization measurement software with a clean, intuitive interface; it comes preloaded with a variety of standard databases, allowing you to start measurements with simple configuration—no lengthy specialized training required.

Application areas

• Metrology Institute: Periodic verification and calibration of various standard gauges and measuring instruments;
• Precision machinery: dimensional inspection of bearings, gears, and non-standard shaft components.
• Tool and gauge industry: factory inspection of thread gauges, pin gauges, and plug gauges;
• Production and quality control of high-precision components for aerospace, instrumentation, and other industries.

From calibration against measurement standards to random sampling inspections of production‑line components, a single device seamlessly supports multiple measurement scenarios, helping companies reduce inspection costs and rigorously maintain product yield.

In an era of ever‑stricter manufacturing precision, reliable data is the ultimate testament to quality. Yezhi Instruments’ fully automated, high‑precision length‑measurement machines uphold every dimensional tolerance, ensuring seamless support for precision manufacturing.
