Application:
This length measuring machine is mainly used to calibrate grade 4 and grade 5 gauge blocks, smooth plug gauges, smooth ring gauges, plug thread gauges, thread ring gauges, master bars of outside micrometers, internal micrometers and self made length bars and various dial gauges, also used to calibrate snap gauges, inside dimension measurement of through holes and blind holes, mid diameter of outside thread etc. This machine is widely used in manufacturing industry, R&D lab and unit, national measuring & metrology departments and labs at all levels.
External dimensions
The measurement of the parallel plane for the measured piece, such as: measuring blocks;
The measurement of the spherical dome for the measured piece, such as: length bars, steel balls;
The measurement of the cylindroid for the measured piece, such as: circular cylinders.
Internal dimensions
The measurement of the parallel plane for the measured piece, such as: snap-gauge;
The measurement of the aperture, such as: ring-gauges.
Screw thread
The measurement of external and internal effective diameter of threads.
Comparative measurement
The large-or-small movable measuring hooks are used to conduct comparative measurements for internal and external dimensions.
