Computer numerical control machining center for cutting workpiece, has screw rod with two opposing thread sections arranged in support along Z-coordinate axis, and work platform and tool holder assemblies alternately arranged on support

摘要

The center has a support (2) extending vertically from a base frame (1) along Z-coordinate axis, and a screw rod (22) with two opposing thread sections arranged in the support along the coordinate axis. A work platform assembly (3) and a tool holder assembly (4) are alternately arranged on the support along the coordinate axis, and the base frame includes two vertical rails (21) that are parallel to each other. The support extends horizontally in the base frame along the coordinate axis. The work platform assembly comprises a Z-axis upper seat (41) and a Z-axis lower seat (31).
