The bearing weight of cast iron bed plate is closely related to its design and actual production and processing. The bearing weight of the bed plate is also related to its length, width and height, the surface accuracy of the bed plate, weight, and material.
For example, a 4000mm*2000mm cast iron bed plate can place a workpiece weighing 64 tons. The load-bearing of this plate can be simply regarded as 64 tons ÷ (4 meters * 2 meters) = 8 tons per square meter. In order to facilitate understanding, we can regard it as the pressure that the cast iron bed plate can withstand after the workpiece is placed on the workpiece without affecting the normal use. The load-bearing of the cast iron bed plate refers to the deformation and deflection after the weight per unit area of the cast iron plate is borne.
The cast iron bed plate shall be periodically subject to periodic verification, generally one year, and the verification period shall be determined according to the detailed conditions of use.
