工业台钻三维线框模型

纯白背景上完整展示一台工业立式台钻的三维线框技术模型，竖幅构图，前左上方略微俯视透视，单件居中展示；浅灰色块面覆盖细密深色网格线，顶部圆弧长条护罩向上翻开并露出内部多级带轮和传动带，右侧有圆柱形电机外壳与护罩结构，中心为垂直立柱，前方有三根带圆球端头的辐条式进给手柄，主轴下端带钻夹头和钻头，下方为可调方形带槽工作台，底部为带安装孔和加强筋的铸件底座；整体呈单色灰阶、机械制图与网格渲染质感，柔和中性光，画面无人物、无文字，画幅比例约1:2。

A single industrial pillar drill press rendered as a light-gray 3D wireframe and technical mesh model on a pure white background, vertical composition, front-left slightly elevated perspective, full machine centered; thin dark mesh edges over shaded gray surfaces; the rounded elongated top belt guard is hinged open upward, revealing stepped pulleys and a drive belt; a cylindrical motor housing and pulley guard on the right; a central vertical column; a three-spoke feed handle with rounded knobs; a spindle chuck with drill bit at the lower end; an adjustable square slotted worktable; a cast base with mounting holes and ribs; monochrome gray-scale mechanical CAD style, soft neutral lighting, no people, no text, aspect ratio about 1:2.
