• High-precision granite base and column

The machine uses a high-precision granite base and column, which offers superior thermal stability and mechanical performance compared to steel and aluminium columns.

• High-resolution grating system

Combined with high-precision linear guides and a high-resolution (0.0001mm) optical scale readout, it enables high-precision and rapid thread measurement.

Large-field high-resolution telecentric industrial lenses and matrix cameras:

• Equipped with a 25-megapixel high-resolution CCD camera, it delivers bright and sharp imaging.
• Paired with a large-field telecentric transmitted light source and bi-telecentric lenses, together with a precision motion control system, it performs optical scanning on thread profiles.

Yuanyue Measurement and Control's exclusive dedicated thread measurement software can measure the key geometric parameters of almost all threads in a very short time, including but not limited to:

• Pitch

• large diameter

• Pathway

• Medium diameter

• Tall teeth

• Root Radius

• Elevation angle

• Helix angle

• Tooth angle

• Right corner

• Left corner

• Roundness / Cylindricity

• Wide measurement range, comprehensive functions

Typically covering a wide range of thread sizes, such as external threads: M1 ~ M100 or even larger, and can be customised according to customer requirements. It can not only measure a single parameter but also conduct comprehensive evaluation, complying with modern geometric tolerance standards.

• Measurement is fast and efficient

 With a single setup, all parameter measurements can be completed in seconds, far surpassing traditional contact thread gauges.

•  Automatic measurement, data traceable

Automatically recognise thread profiles, compare them with standards (ISO, DIN, GB, etc.) or customised tolerance zones, automatically determine OK/NG; automatically generate detailed measurement reports (PDF, Excel), supporting SPC statistical analysis.

All measurement data is electronically stored for easy quality traceability and analysis.

•  Non-contact measurement

It does not cause scratches or pressure deformation on the thread surface, making it especially suitable for soft, coated, polished, and high-gloss threads.

•  High precision

The measurement accuracy reaches the micron level, meeting the requirements of high-precision manufacturing.

•  Intelligent solutions

Specialised non-contact laser probes can be selected according to customer requirements to measure the inner inclination angle of fastening flanges and the root fillet radius.

It can integrate robots for automatic loading and unloading, forming a fully automatic thread measurement station.
