Manufacturing method of supporting base for separation of effective compositions of plant herbs

The invention relates to a manufacturing method of a supporting base for separation of effective compositions of plant herbs. The manufacturing method comprises the following steps of casting, whereinaccording to the size of a supporting base finished product, 10-12 mm of machining allowances are reserved in both sides, a casting head is reserved at the small end, and a supporting base blank is completed through one-time casting; detection, wherein dye checking or X-ray crack detection is conducted; pellet blasting; benching, wherein a height machining line and a circumference machining lineare drawn with the large-end stepped end face of the supporting base and the external circle at the root of the step as the reference plane; rough machining; low-temperature aging treatment; detection; dye checking; semifinishing; low-temperature aging treatment; finish machining; finish turning, wherein the external circle plane of a slider is machined to the size; right boring, wherein the two stepped holes must be clamp
