JD700-HA
High Accuracy Universal Length Measuring Machine
Characteristics
Adopts imported high accuracy reflection grating scale system from Germany, length value measured can be showed on computer to realize on time grating reading display.
Temperature errors can be compensated on time, equipped with temperature sensors, software can realize real time temperature error compensation automatically.
High quality granite base, with strong stiffness and stability without deformation.
Equipped with complete accessories to satisfy various measurement applications and requirements.
Square main measuring axis is designed to guarantee stability during movement when measurement was made.
Data collection function: Collect coordinate points of workpiece and carry out corresponding processing.
Measurement function:Absolute measurement on outside dimension and inside dimension, inner dimension, screw measurement.
Automatic temperature compensation, with machine temperature and workpiece temperature real-time display.
Reminder function:Measurement procedure will be showed on time.
Special chart display window for inflection point in software interface, easy to operate.
Measured data can be export to AutoCAD, Word etc or go directly to print test report.
Machine 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.
