机床主要结构特点：

机床结构：机床为数控落地式铣镗床，即床身落地、工作台落地，镗轴、铣套均装在矩形方滑枕内。TK6920数控落地铣镗床主轴箱采用镗杆+铣轴的结构形式。

机床由立柱、床身、拖板、主轴箱等组成；立柱在拖板上随拖板在床身上横向移动，拖板由床身支承；主轴箱沿立柱侧面上下移动；移动式方滑枕安装在主轴箱的闭式方孔内，铣轴安装在方滑枕内带动镗轴作旋转运动，镗轴在铣轴内可轴向移动。

床身、立柱、拖板、主轴箱箱体及滑枕等大件均采用树脂砂造型、高强度无应力铸铁件，德国先进的树脂砂铸造设备，为生产出高质量的铸铁件，提供了可靠的保证。所有大件均经过时效处理，消除内应力后再进行加工。立柱上有两条矩形镶钢导轨，立柱内腔加强筋布置合理，使立柱具有高刚度和高抗震性。

床身由两排地脚螺栓与地基固定，调整方便，牢固可靠。

数控系统采用西门子840D。
