请教双面研磨机问题

哪位朋友做过双面研磨机工艺?能否想您请教?一般的窗口片从2.0到1.0MM研磨应该把速度和轻压,自重圈数调到多少?还有研磨液该怎么配比,用什么样的砂子会更好?

<P>如果需要1.0的产品,我们一般是不会用2.0的玻璃来做的。最多用1.1或者1.2的坯料来加工。</P>
<P>当然如果数量少的话,也可以用2.0的玻璃慢慢来。速度、轻压、圈数等等需要根据不同的设备和每盘放置的工件数量来确定,也就是说根据工件与磨盘的总的接触面积而定。</P>
<P>研磨液的配比,给你一个参考方案:1公斤磨料+3公斤水+250克防锈剂,浓度不应小于20%。</P>
<P>研磨最好可以分两道,最后一道研磨用细一点的砂,对于抛光来说,可以大大提高抛光效率。</P>

<P>
金刚砂的选择一般越细越好,但是太细了对减薄砂轮的寿命有影响。</P>
<P>一般国内的做法是:【粗磨】--【细磨】--【精磨】三个步骤</P>
<P>设备以及耗材很关键</P>
<P>『1公斤磨料+3公斤水+250克防锈剂,浓度不应小于20%』除了这种外,还有用纯水冷却,根据工艺不同选择。</P>
