Tri-dimensional oral prosthesis in vitro grinding and repairing emulated testing machine

[0024] The present invention is a kind of three-dimensional dental prosthesis in vitro grinding repair testing machine, this testing machine ( figure 1 ) includes four columns 1, which are rigidly connected with the lower base plate 17 and the upper top plate 11, and they form a frame. The size of the rack is small, its length, width and height are: 300×250×250mm. The upper top plate and the lower bottom plate have a high degree of parallelism, thus ensuring that the 3D CNC workbench can run precisely according to the established requirements. 3D CNC coordinate table ( figure 2) consists of three numerically controlled workbenches with the same structure: a workbench 6 capable of moving left and right in the X direction, a workbench 7 capable of moving forward and backward in the Y direction, and a numerical control workbench 9 capable of moving up and down in the Z direction, and the axes of the three workbenches are in the The space is distributed vertically. Each workbe...
