二、主機結構

II.        Main engine structure

由上橫梁、中橫梁、下橫梁及底面板通過兩對滾珠絲杠和立柱構成框架結構。由全數字交流伺服電機驅動減速機及同步齒型帶，帶動兩對高精度無間隙的精密滾珠絲杠轉動，驅動橫梁上下移動。

The engine structure is formed by the upper beam, the middle beam, the lower beam and the bottom panel with two pairs of ball screw-rod and a vertical column. The all-digital AC motor drives the reducer and the synchronic gear belt, so as to turn two pairs of high-precision and seamless ball screw-rod, and to make the beam move up and down.
