[0002] The existing announcement number is CN 220555000 U, a precision mechanical anti-deformation processing platform. Through the provision of inverted T-slots and bolts, it is convenient for personnel to install multiple support plates or support plates of different processing sizes on the workbench according to actual processing needs. Through the provision of positioning components and positioning holes, it is convenient to insert and position the sheet to be processed through the column before processing, thereby ensuring that when the tool processes the sheet, the deformation of the sheet to be processed can be effectively reduced, ensuring processing efficiency and reducing processing costs. However, the above-mentioned positioning components only limit the processing sheet in the horizontal direction, and do not limit the axial direction of the column, which may cause axial runout during processing, thereby affecting processing accuracy.
