要在和铣床工作台行程一样长的3.2mm厚的铝板两端加工出台阶,台阶深度为1.524±(?),两台阶间板的宽度必须保持在±0.127mm内。由于深度以上面为基准,板又薄又长,装夹比较复杂。若设计一个如图所示附件,既能调整所切深度,又能提供夹紧压力,以便一次走刀即可加工完。桥式支架上装有滚珠 The steps are to be machined at both ends of a 3.2mm thick aluminum plate of the same length as the milling table with a step depth of 1.524 ± (?). The width of the two step plates must be kept within ± 0.127mm. As the depth of the above as a benchmark, the board is thin and long, more complicated folder. If the design of an attachment as shown, both to adjust the depth of cut, but also provide clamping pressure, in order to pass the knife can be processed. Bridge bracket with balls
