The working fluid is injected into the liquid storage tank 3. The workpiece can then be processed by the processing equipment body 2. Subsequently, the working fluid in the liquid storage tank 3 is extracted by a water pump. The debris on the detachable worktable assembly 4 is cleaned by quickly disassembling the detachable worktable assembly 4.

[0036] The workbench body 401 can slide stably inside the liquid storage tank 3 through the surrounding sealing rings 402, thereby preventing leakage of the working fluid in the liquid storage tank 3. The positioning sliders 404 at both ends of the slide rail 403 inside the workbench body 401 are placed into the inner sides of the convex groove of the mounting plate 407. At this time, the spring 406 squeezes and pushes the two sets of positioning sliders 404 to move, thereby providing the locking block of the positioning slider 404 to engage with the inner wall of the convex groove of the mounting plate 407. The guide rod 405 on the positioning slider 404 can provide the spring 406 to stably squeeze and push, providing a quick connection between the workbench body 401 and the mounting plate 407. Afterwards, the positioning slider 404 no longer continues to be in the convex groove of the mounting plate 407, so that the workbench body 401 can be quickly removed, making it easy to clean up the debris on top.

[0037] When the height of the workbench body 401 needs to be adjusted, the cylinder 503 is activated to drive the push rod 505 to produce a horizontal displacement. At this time, the push rod 505 can move horizontally stably on the track 504. The push rod 505 is located in the sliding hole 506 of the mounting plate 407. When the push rod 505 moves horizontally, it will provide the mounting plate 407 with a vertical displacement.
