AI Technical Summary
When CNC machine tool workbenches are subjected to gravity and processing pressure, they require good pressure bearing capacity, but hollow design to reduce costs will lead to dense or evacuation of support structures, which can easily increase costs or lead to concave phenomena.
A structure including a countertop panel, a T-groove, a support frame, a slider fixed column, a support ring and a reinforcement plate is designed. Through a uniformly distributed support plate and annular structure, the support force and force strength of the workbench are enhanced.
It is achieved to ensure the cost of casting materials while providing sufficient support structure strength to avoid concave when the CNC machine tool table is under high stress.

Technical Field
[0001] The utility model relates to the technical field of metal castings, in particular to a metal casting for a numerically controlled machine tool. Background Art
[0002] Metal castings are metal objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling and subsequent processing such as grinding, the resulting metal object has a certain shape, size and performance;
[0003] In the process of using the metal casting of the worktable in the CNC machine tool, the worktable of the CNC machine tool serves as a fixed platform for placing the workpiece processed by the CNC machine tool. The worktable of the CNC machine tool needs to withstand the gravity of the workpiece placed on the upper side thereof, and at the same time needs to withstand the pressure generated by the CNC machine tool milling cutter processing the workpiece on the worktable. Therefore, the worktable of the CNC machine tool needs to have a relatively good pressure-bearing capacity. In order to reduce the casting material cost of the CNC machine tool worktable, the inner side of the CNC machine tool worktable is mostly hollow, and a good support effect on the plane on the CNC machine tool worktable is achieved through the support structure on the inner side of the worktable. However, a dense arrangement of the support structure on the inner side of the worktable is likely to increase the casting cost of the CNC machine tool worktable. A sparse arrangement of the support structure on the inner side of the worktable is likely to cause the CNC machine tool worktable to be concave when subjected to a large force. Therefore, a CNC machine tool metal casting is proposed to address the above problem. Utility Model Content
