Description
Universal length measuring machine is compact, and it is equipped with high precision reflective grating, suitable for the detection of all kinds of precision machining parts. The measuring spindle designing adopts the optimized square so that it has good stability during measuring. The software has a variety of international standards and 39 other verification standards database, and the report output format can be customized.
Feature
Universal length measuring machine is mainly used for the absolute measurement and comparative measurement of various internal and external dimensions, the measurement of external micrometer calibrators, internal micrometer gauges and self-made micrometer gauges, the measurement of the sizes of clamps, through holes or blind holes and the measurement of the middle diameter of external threads. It is widely used in various fields.
