4英寸以下成套的水煤气焊管轧辊的圆弧半径R值的变化范围都是很大的,通常在R10～R600mm左右。特别是初轧轧辊的圆弧半径尺寸的加工(见图1)都基本上有这样几个特点,即:(1)轧辊的外径大;(2)轧辊的圆弧半径R值大;(3)轧辊呈多圆弧相切。所以,在普通中、小车床上加工这类轧辊,都是很困难的,即使制作专用工装,亦往往由于工件直径大和机床中心横向位置所限,而难以实施整圆弧的加工,况且工装制造费用也很大。我们采用如图2所示的在卧铣上(X63W,或X63
4 inches below the complete sets of water gas pipe roller arc radius R value range is very large, usually around R10 ~ R600mm. In particular, the initial radius of the rolling roll radius of the size of the processing (see Figure 1) are basically the following characteristics, namely: (1) the outer diameter of the roll; (2) roll radius of the arc R value; ( 3) roller tangent arc. Therefore, it is very difficult to process such rolls in ordinary middle and small lathe beds. Even if special tooling is made, it is difficult to carry out the processing of full arc due to the large diameter of the workpiece and the lateral position of the machine tool center. Moreover, the manufacturing cost of the tooling Also great. We use the horizontal milling shown in Figure 2 (X63W, or X63
