Preparation method of stainless steel clamping ring

The invention provides a preparation method of a stainless steel clamping ring. The method comprises the following steps: (1) placing a stainless steel original ring in a clamping part, and sequentially carrying out rough machining with the cutting depth of 0.1-0.3 mm and finish machining with the cutting depth of 0.1-0.2 mm to obtain a middleware; and (2) sequentially performing primary cleaning and drying, surface coating and secondary cleaning and drying on the middleware in step (1) to obtain the stainless steel clamping ring. According to the preparation method, the stainless steel clamping ring with the thickness of 1-1.5 mm can be prepared, the inner roundness and the outer roundness of the stainless steel clamping ring are both 0.15 mm or below, and the machining precision is improved. 本发明提供一种不锈钢夹环的制备方法，所述制备方法包括如下步骤：(1)将不锈钢原环置于夹持部件中，并依次经吃刀量为0.1～0.3mm的粗加工和吃刀量为0.1～0.2mm精加工，得到中间件；(2)步骤(1)所述中间件依次经一次清洗干燥、表面镀膜和二次清洗干燥，得到所述不锈钢夹环；所述制备方法能够制得厚度为1～1.5mm的不锈钢夹环，其内外圆度均在0.15mm以下，提高了加工的精度。
