2、 Mechanical structure

This testing machine is fixed to the crossbeam and worktable by a column and two precision ball screws. It uses an AC servo motor and driver to drive two pairs of high-precision, gapless precision screws through a synchronous toothed belt to move the crossbeam up and down. It has the characteristics of reasonable structure, high rigidity, smooth loading, and good stability performance.
