Abstract
According to the technology for manufacturing the thick-edge pot body through heating, a spinning wheel is used for machining a wafer base material, the spinning wheel comprises a connecting disc, an annular concave position, a first convex position step and a second convex position step, the annular concave position is located between the connecting disc and the first convex position step, and the second convex position step is connected to the first convex position step; the diameter of the outermost edge of the first convex step is larger than that of the outermost edge of the second convex step; the technology for manufacturing the thick-edge pot body through heating comprises the following steps of spinning preparation, heating treatment, edge thickening, thin-wall spinning, thick edge forming and thick edge shaping. According to the invention, the problem that a pot body with a thick edge cannot be processed from a wafer base material with relatively high strength is solved.
