Abstract

A numerally controlled machine-tool for machining the magnetically levitating rail is composed of main body with 36 m in length, vertical column, mainshaft box, control system and manipulating station. It features its other units including three drive mechanisms for X, A and B axises, a slide seat of vertical column, a rotary seat of vertical volumn and a slide saddle moving along vertical column. The said mainshaft box is arranged to slide saddle. The said control system and manipulating station are connected to slide seat. Its advantage is high precision in whole length range of workpiece.

Description

Technical field:

[0001] The invention belongs to metal cutting machine tools, in particular to a metal cutting numerical control machine tool suitable for super-long and super-heavy components such as magnetic levitation track beams. Background technique:

[0002] The prior art closest to the present invention is a floor-type CNC milling and boring machine. The layout and movement mode of the existing floor-type CNC milling and boring machine are that the column moves laterally on the bed to form the X-axis; the ram headstock moves up and down on the column to form Z axis; the longitudinal movement of the ram and the main shaft constitutes the Y axis. This layout and movement mode only has a linear axis, no rotary axis, and the moving range of the X axis is within 15 meters. This kind of floor CNC milling and boring machine generally adjusts the workpiece or uses a rotary table to adjust the machined surface of the workpiece to be perpendicular to the axis of rotation of the...
