直径在26mm以上的钢球毛坯,在去除环带后,都需进行初磨加工,以磨去大部份加工留量。 一、初磨设备及加工方法 1.初磨设备 钢球初磨加工用的设备型号为3M4550。其主要技术参数如下:加工钢球的最大直径50mm(经改进后可加工到80mm);砂轮直径600mm;砂轮转数1000r/min;主电动机功率75kW;机床加工精度为不圆度0.08mm,同盘球直径公差0.16、光洁度5;机床重量7.5Mg;机床外形尺寸(长×宽×高)1915×2193×2910mm。
Ball blanks with a diameter above 26mm require initial grinding to remove most of the machining allowance after removing the annulus. First, the initial grinding equipment and processing methods 1 initial grinding equipment ball grinding process with the initial equipment model 3M4550. Its main technical parameters are as follows: the maximum diameter of the steel ball processing 50mm (improved to 80mm); wheel diameter 600mm; wheel speed 1000r / min; main motor power 75kW; machine tool processing accuracy of non-roundness 0.08mm, with Ball diameter tolerance 0.16, finish 5; Machine weight 7.5Mg; Machine Dimensions (L × W × H) 1915 × 2193 × 2910mm.
