Operation Process

The operator installs the test piece, selects the standard of the test piece and inputs its specifications in the detection software, then moves the headstock to contact the test piece, adjusts the five-axis worktable to find the inflection point, completes sampling to obtain measurement data. The system can display measurement results in real-time, automatically calculate various parameters of the test piece (e.g., automatically calculate the pitch diameter when inspecting thread gauges), and perform pass/fail judgment based on the system's built-in standard database. Results and record reports are automatically generated upon completion.

Performance Features
