带直通孔奥氏体不锈钢圆球,广泛用于各种球阀及其他防锈机械设备。由于球带直通孔,研磨加工不便,多在机床上用专机旋铣加工,此法简便,切出的圆精度较高(可达八级)。对光洁度要求高的球,由于奥氏体钢抛光性好,旋制后可直接抛光,省去磨削工序,降低成本,提高生产率。一、旋球方法和产生圆度误差的因素在机床上精旋圆球,是把毛坯球先钻出精度较高、轴线大体通过球心的通孔,然后将心轴和其上套装弹簧夹头部分一起穿入球直孔中,当弹簧夹头胀开,即可把球坯(工件)与心轴连为一体。在机床拖板(或专机座)上安固定刀座,刀座上安可旋转刀轴,
With through-hole austenitic stainless steel ball, widely used in various ball valves and other rust-proof machinery and equipment. Due to the ball through the hole, grinding process inconvenience, and more in the machine with a plane milling machine, this method is simple, cut out of high precision (up to eight). The requirements of the ball on the finish, due to good austenitic steel polishing, spinning can be directly polished, eliminating the grinding process, reduce costs and increase productivity. Spinning method and the factors that produce roundness error Spinning the ball on the machine is to drill the rough ball first with high precision, the axis passes through the center of the ball through the hole, and then the spindle and the spring clip on the suit Head part together into the ball straight hole, when the spring chuck open, you can blank (workpiece) with the mandrel as a whole. On the machine drag plate (or special plane seat) on the security fixed knife seat, knife seat on the rotary knife axis,
