High AccuracyMetrology Institute Use Iso 17025 Gauge Length Measuring and Calibration Instruments

Thanks to precision glass-scale, precision guide rail and precision temperature compensation unit, cooperating with different probes and workholders, SJ5100 achieves high-precision measurement of various dimensional gauges. Moreover, because straightness of precision guide rail is every small, its repeatability is excellent by applying by bidirectional constant measuring force technology. After the software records the coordinates from precision glass-scale and introduces the feedback data of measuring force device and temperature sensor, the dimensional parameters are calculated according to the relevant definitions and formulas from selected norm. The whole measurement process can be completed in 3minutes.

1.Absolute measurement:
Thanks to precision glass-scale for positioning of measuring spindle, SJ5100 can implement the precision absolute measurement over the entire range.

2.High precision and High stability:
(1) Precision glass-scale; Resolution: 0.01μm.
(2) Precision grinding guide rail with excellent straightness lays foundation for accuracy and stability of measurements.
(3) Measuring values are acquired truly and accurately by using high-rigid and deformation-free measuring slider.
(4) Thanks to marble base, the machine is protected against external vibration interference, which ensures stable and reliable working.
(5) The headstock is very stable during travel by using compact friction driving structure.

3.Bidirectional constant measuring force:
(1) Bidirectional constant measuring force system reduces the influence of measuring force on measured values, which helps to improve the accuracy of measurements.
(2) Manual continuously-adjustable measuring force.
(3) The smart sensing system of measuring force eliminates error caused by un-horizontal position of the machine and surrounding environment vibration automatically.

4. Intelligent management and measurement software system:
(1) More than 15 years of practical experience in the design of measurement software; User-friendly software is designed for customers to operate the system fast.
(2) Operation of the machine is simple, so the operator can be trained to use it shortly.
(3) With built-in a variety of norms, the powerful software can process the measured data and generate various test reports automatically.
(4) Can calculate various dimensional parameters for different gauges according to selected norm.
(5) The operator can find the inflection point of workpiece fast and simply though the guide function of software.

5.High-performance five-axis object table:
(1) High-performance cross-roller for rails of X, Y, Z axis: very small friction, excellent stability and large loading capacity.
(2) Function of fine adjustment of Y-axis travel & tilt & horizontal rotation is designed for the operator to find the inflection
point of each axis easily.
(3) The software can collects data automatically from Z-axis digital dial indicator(standard) and Y-axis digital dial
indicator(optional), which is used for measurements of taper thread gauges and taper plain gauges.

6.High-performance inside size measuring unit:
With this unit, SJ5100 can calibrate small ring gauges(the min thread ring gauge is as small as M3; plain ring gauge is as small as diameter ≥0.5mm). Adjustable measuring force is 0.3N~10N; Repeatability of plain ring gauge’s measurements is less than 0.1μm.

*Note:
Optimum working temperature is 20℃.
