SJ5100-Prec300 high-precision grating length measuring instrument

The SJ5100 series high-precision grating length measuring machine adopts imported high-precision grating measuring system, high-precision grinding linear guide rail, high-precision temperature compensation system, two-way constant 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 ultra-high linearity of the measuring head movement. An imported high-precision grating measuring system records the length direction coordinates. The computer synthesizes the data after correcting the grating data with the feedback data from the force measuring device and temperature sensor and the Abbe error data (due to the high linearity of the guide rail, the instrument error caused by Abbe correction is minimal). Relevant length parameters are calculated based on the relevant definitions and formulas of the measured part 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 head to contact the workpiece, adjusts the five-axis worktable to find the inflection point, completes sampling to obtain the measurement data. The system can display the measurement results in real time, automatically calculate the various parameters of the workpiece (such as automatically calculating the pitch diameter of the thread gauge), and make a pass/fail judgment of the various parameters of the workpiece based on the standard database built into the system. The entire measurement process takes no more than 3 minutes, and a result and record report is automatically generated at the end. The standard system software is a simplified Chinese operating system (English, Russian, and other languages can be selected), and the operation is convenient and simple.
