北重提供各种研磨平板，铸铁研磨平板的特点及用途：
研磨平板 特性：
1.操作简单，上砂快，嵌砂量足，使用后仍十分容易上同类型砂，经过打磨后,光洁度显著提高.
2.容易得到量块所需的较高光洁度和研合性,工件镜面青亮.
3.平板耐用,切削足而持久,轻度导砂后仍有良好的切削性,推研时感觉流畅.
Features of Lapping Surface Plate:
Easy and quick in embedding emery,
which can ensure the surface is embedded with sufficient amount of emery and
can be easily embedded the same type emery powder after using and smooth finish
will be significant improved after further grinding.
Easy to achieve high
degree of finish and grinding property that required by gauge block.
The surface plate is featured
with good and persistent machinability and has a long service life.
研磨平板的研磨方法
Lapping Method.
用研磨工具和研磨剂，从铸铁平板工作面上去掉一层极薄表面层的精加工方法称作研磨加工，研磨加工一般可分为湿研、干研和半干研三种加工方式，通常用于铸铁平板表面处理的研磨方法是干研（即嵌砂研磨）。嵌砂研磨又可以分为三板互研法和二板互研法两种研磨方法。
Lapping finish is a precision
machining process, in which a thin layer will be removed from the working surface
of the cast iron plate by using grinding tools and abrasives. According to the
process method, lapping method can be divided into wet lapping, dry lapping and
semi-dry lapping. Dry lapping, also know as embedded emery lapping, is the
common used finishing method for cast iron surface plate. |
