The steel structure cross beam is simple in structure, high in strength due to the fact that the steel structure cross beam is made of carbon steel and supported by a plurality of triangular rib plate structures, and applicable to numerical gantry boring-milling machines with different sizes.

Description

A steel structure beam of a CNC gantry boring and milling machine

technical field

The utility model relates to the field of numerically controlled gantry boring and milling machines, in particular to a steel structure beam of a numerically controlled gantry boring and milling machine.

Background technique

CNC gantry boring and milling machines are widely used in various machining fields. The beams of current CNC gantry boring and milling machines are generally made of cast iron, but the weight of cast iron is relatively large, and the tensile strength, maximum strength and elastic coefficient of cast iron It is not as good as carbon steel, and the inside of the current beam is generally simply welded with several support plates. The strength of such a beam is not enough for some large-span CNC gantry boring and milling machines.
