Gantry milling machine developed as a customized solution for a railway sector client, specifically designed for machining large-format parts used in tracks and turnouts.<\/p>\n

This machine primarily works with manganese steel<\/strong>, a high-hardness material commonly used in these types of applications.<\/p>\n

It features a configuration with 3 continuous motion axes (X, Y, Z) and an automatically positionable A axis<\/strong>, enabling machining on both flat and inclined planes. Additionally, it is equipped with a dual-pallet table system<\/strong> that allows tandem operation, optimizing loading and unloading times and increasing productivity in repetitive tasks. <\/p>\n

It also includes an automatic tool changer<\/strong> and a chip collection<\/strong> system, ensuring process efficiency and continuous cleanliness during machining.<\/p>\n
