A tiny thread hides a major hidden risk? This machine solves all thread‑precision challenges.

Many people view threads as mere inconspicuous little features in mechanical assemblies. Yet in the field of precision manufacturing, even micrometer‑scale deviations in thread geometry can lead to equipment loosening, sealing failures, and outright scrapping of entire machines.

Traditional thread inspection has long suffered from key shortcomings: manual segmented measurements, incomplete parameter acquisition, inconsistent readings due to human variability, and difficulty in calibrating non‑standard thread profiles. Even parts that appear to meet specifications often exhibit hidden issues such as poor assembly fit and unstable dimensional accuracy.

The Yechi Instrument Thread Comprehensive Measuring Machine was specifically designed to address the industry’s longstanding challenges of inaccurate, incomplete, and inefficient thread measurement, enabling micron‑level thread precision that is quantifiable, traceable, and virtually error‑free.

Unlike traditional single‑parameter sampling inspections, this equipment supports one‑click, full‑field scanning and measurement, accurately capturing all critical thread parameters in a single pass—major diameter, minor diameter, pitch, thread angle, profile deviation, taper, and more—fully reconstructing the thread’s true dimensional accuracy and eliminating missed or erroneous inspections.

Highly compatible, it effortlessly accommodates standard and non‑standard threads—including cylindrical, tapered, and trapezoidal types—and can precisely inspect both internal and external threaded components, as well as thread ring gauges and plug gauges, truly enabling a single instrument to measure all thread types.

Intelligent automated inspection—say goodbye to human error.

The device is equipped with a high-precision scanning system and intelligent measurement‑control software, enabling fully automated alignment, data acquisition, and computation throughout the entire process. It eliminates the need for manual recalibration and segmented measurements, thereby minimizing errors introduced by human reading and operation, and maximizing the repeatability and stability of the measurement data.

Upon completion of the measurement, a visual contour curve and a standardized calibration report are automatically generated, with full traceability of all data. The system fully complies with national standards and international metrological standards, effortlessly meeting requirements for metrological compliance and measurement‑value traceability.

Multi‑scenario adaptability, fortifying the defense line of precision manufacturing accuracy.

It can efficiently adapt to a wide range of applications, from gauge periodic verification and metrological traceability at national metrology institutes and third-party calibration organizations, to high-end manufacturing sectors such as aerospace, automotive components, precision molds, and hydraulic machinery.

We precisely control the machining accuracy of every thread, addressing at the source issues such as thread‑fit deviations, equipment loosening and leakage, and low first‑pass yield, while leveraging precision metrology to safeguard the overall product quality and stability.
