High-precision length measuring machine is mainly used for absolute measurement and comparison measurement of the internal and external dimensions of various workpieces. Measurement objects include gauge blocks, smooth plug gauges, smooth ring gauges, threaded plug gauges, threaded ring gauges, outside micrometers, inside micrometers, calibration rods, indicator gauges, and clamps.
->Precision reflection grating system imported from Germany, high measurement accuracy;
->Real-time temperature error compensation, equipped with a temperature sensor, can automatically complete real-time temperature error compensation;
->The base adopts high-quality granite base, which has good rigidity and stability.
->The measuring spindle adopts an optimized square design to ensure the stability of the movement during measurement;
->Complete measurement accessories, wide range of use, can meet different measurement requirements;
->Inflection point icon: the software interface has an inflection point icon, which is very easy to operate；
->Testing of various standard gauges,such as GB, ISO, DIN, JIS, ANSI, BS
->The software has 39 kinds of standard databases including gauge blocks, ring gauges, plug gauges, card gauges, calibration rods, rulers, dials, etc., which meet a variety of verification regulations and standards, and automatically determine the test results according to the regulations and standards;
->The measurement data can be outputted according to the measured name, number, inspector, inspection unit, equipment number, verification date and valid date, etc. The output format is WORD or EXCEL, and the report output format can be customized according to requirements
