The CNC fixed beam gantry rail milling machine is a specialized machine tool developed and designed to meet the needs of railway machinery manufacturing for processing railway rail parts. It combines the structural characteristics of modern gantry milling machines and modern machine tool technology to process high carbon steel rails.

The CNC fixed beam gantry rail milling machine can be equipped with one or two sliding pillow type main milling heads for the crossbeam according to the width of the worktable, and has three or five feed axes (worktable X axis; Boring and milling head-Y, Y1 axes; The sliding sleeper-Z/Z1 axis can achieve three-axis linkage. All major components of the CNC fixed beam gantry steel rail milling machine are made of cast iron molded with resin sand. The spindle can automatically pull the blade and achieve 90 degree automatic orientation. The slider has a hydraulic balance device, the crossbeam has a roller embedded steel guide rail unloading device, and the worktable bed body guide rail adopts a closed static pressure guide rail with small flow multi head constant flow oil supply.
