[0002] The transmission mechanism of traditional machine tools (such as XYZ and other moving axes) is generally protected by an accordion-type telescopic protection structure or a multi-layer steel plate telescopic protection structure. However, for some processing and cutting very fine, such as brittle and hard materials with powdery chips. When using a multi-layer steel plate telescopic structure as protection, there are small gaps between each layer of steel plates, and powders can easily enter the transmission parts from the gaps, causing damage to the transmission parts. As for the accordion-type telescopic protection, there are many wrinkles on the top surface. After long-term use, powders and other chips will accumulate in the wrinkles, causing the telescopic protection to be easily hindered from compression or perforated when it is retracted.

[0034] Specifically, see Figure 1 and Figure 2 The transmission table 220 is arranged on the upper side of the active table 210, and the machine tool workpiece is fixed on the upper plane of the transmission table 220. The active table 210 drives the transmission table 220 and the workpiece to move along the machine tool bed 400 to process the workpiece. Among them, the active table 210 is arranged below the protective steel plate 110, and the front and rear sides of the active table 210 protrude from the front and rear sides of the protective steel plate 110 respectively.
