Instrument parameters

Measurement function

Workpiece eccentricity compensation: The reference axis of the clamped workpiece does not coincide with the eccentricity of the instrument's rotation axis. The Jinliang software system calculates the eccentricity and deflection errors for sample detection, and then performs precise compensation for the eccentricity and deflection errors during measurement and measurement results. This technology improves the precision measurement accuracy of gears with large center hole deviation or without center hole and internal gears. In the domestic gear measurement industry, Jinliang has taken the lead in breaking through this technology and achieved the latest linear correction of positive and side busbars, compensating for instrument loss errors, improving the later use accuracy and measurement accuracy of the instrument, truly achieving superior and reliable high-end quality

Technical characteristics

A stable and efficient host system, including mechanical systems: the main spindle (worktable C-axis) is a DDR motor servo system, combined with high-resolution closed circular grating and high-precision dense ball axis system, which makes the load-bearing capacity strong and smooth during movement; Three linear axis DDR linear motor drive systems, high-precision registration linear guide rails and rolling linear ultra high precision cage motion units, combined with high-precision and high-resolution gratings

Imported 3D digital probe sensor: The 3D scanning digital probe is sourced from the RENISHAW brand in the UK, with the model number "SP80H". The SP80H shaft mounted scanning probe adopts digital scale and reading head technology, combined with innovative separation optical measurement principles, which can provide excellent scanning performance even with long measuring needles

Repeatable needle exchange for convenient, fast, and flexible detection of workpieces

SP80H has mechanical positioning and can be used as a probe exchange to repeatedly reposition the probe, providing a combination of probes for each feature measurement without the need for recalibration. Installing SP80H can turn on/off the measuring head, without the need to return to zero when the system is powered on and restarted
