Dimension measurement
Laser interferometers use light waves as carriers. Their light wave wavelengths can be used to directly define meters and can be traced back to national standards. They are recognized as high-precision, high-sensitivity measuring instruments and are widely used in high-end manufacturing. The SJ6000 laser interferometer has the advantages of high measurement accuracy, large measurement range, fast measurement speed, and high resolution at the highest measurement speed. Combined with different optical lens groups, it can achieve high-precision measurement of linear length, angle, straightness, verticality, parallelism, flatness, and other geometric parameters. With the cooperation of the SJ6000 laser interferometer dynamic measurement software, dynamic measurement and performance testing of linearity, angle, and straightness can be realized, and displacement analysis, velocity analysis, acceleration analysis, and FFT analysis can be performed, such as dynamic characteristic analysis of screw rod guides, vibration analysis, and response characteristic analysis of drive systems.
The step instrument is an advanced micro-nano measuring instrument with independent intellectual property rights owned by Zhongtu Instrument. The instrument adopts core technologies such as sub-angstrom resolution displacement sensors, ultra-low noise signal acquisition, ultra-fine motion control, and calibration algorithms, and has excellent performance.
SJ5100 High-Precision Grating Length Measuring Machine
The grating length measuring machine adopts imported high-precision grating measurement system, precision grinding guide rail, high-precision environmental compensation system, two-way constant measuring force system, and high-performance computer control system technology to achieve high-precision measurement of various length parameters. The high-precision grinding guide rail ensures the high stability and linearity of the measurement travel. A German-imported high-precision grating measurement system is used to record the length direction coordinates in contact measurement. The computer synthesizes the data, the measuring force device, and the feedback data of the temperature sensor, and analyzes it according to the relevant definitions and formulas of the measured parameters to calculate the relevant length parameters. The operator installs the workpiece, selects the standard of the workpiece and inputs the specifications of the workpiece on the detection software, moves the headstock to contact the workpiece, adjusts the five-axis workpiece platform and the head and tail seats to find the inflection point, completes the sampling to obtain the current measurement data, the system can display the measurement results in real time, automatically calculates the various parameters of the workpiece (such as detecting the thread gauge, the thread mean diameter can be converted and displayed), and performs qualified judgment on the various parameters of the workpiece according to the standard database built in the system. The entire measurement process takes no more than 3 minutes, and the results and reports are automatically generated after the detection. The instrument measurement principle conforms to JJG 343-2012 Inspection Regulations for Smooth Limit Gauges, JJG 146-2011 Inspection Regulations for Gauge Blocks, JJG 21-2008 Inspection Regulations for Vernier Calipers, JJG 22-2014 Inspection Regulations for Inside Vernier Calipers, JJG 62-2017 Inspection Regulations for Feeler Gauges, JJF 1207-2008 Three-Pin/Pin Gauge Inspection Specifications, JJF 1345-2012 Calibration Specifications for Cylindrical Thread Gauges (tolerance reference GB/T 3934-2003), etc., length inspection regulations.
