研磨平板（研磨平台）是一种为了能够保证工件精度和表面光洁度而利用涂敷或压嵌在研磨平板上的磨料颗粒，通过研磨平板与工件在一定压力下的相对运动对加工表面进行的精整加工而衍生的一种铸铁平板。
研磨平台用途：
　　研磨平板用于量具的制造、修理， 制件研磨，高精度机械零件制作，光学仪器的加工。
　　用研磨工具和研磨剂从工件上研去一层极薄表面层，使工件具有准确的尺寸和形状以及很高的表面质量，这种加工方法叫研磨。研磨属于精加工工序，他在工具、量具和精密机械制造中具有广泛应用。随着机械工业的发展，研磨也由手工操作逐步趋向于机械化。
      研磨平板的要求:研磨平板表面要光滑，无裂痕、斑点等缺陷；材质一般用灰铸铁，它具有润滑性能好、研磨效率高、磨耗相当小等优点。尤其适用于精研。
压砂平板简介：
　　压砂平板是检验各种精密另件的面性（用光隙法），修理各种量块、工卡量具、光学另件及测量精度和另件的工具的平直度的工具。压砂平板做为修理量块的唯一计量器具，它的好坏将直接影响着量块的修理质量。
      压砂平板：压砂平板是工件进行超精研磨时用的平板。研磨方法：研磨前，将细微的研磨剂均匀洒在两平板之间，然后，使平板相互对研，细微粉粒嵌入平板之工作表面，构成具有一定牢固性“多刃研削面”。经过压砂平板研磨后，工件表面的纹路细密，能得到准确的尺寸和很高的表面质量。
    使用压砂平板常见问题：
    切削不均匀：由于研磨剂不均匀，解决方法是将研磨剂涂匀。
    切削规律划伤：由于混进了粗砂粒，解决方法用天然油石打掉粗砂粒。
    表面颜色发黄：由于平板表面已无切削力，方法是重新压砂。
    无规律划伤：由于平板表面有岩屑混入，方法是清洗表面，少涂一滴硬脂后用汽油稀释。
The grinding plate (ground platform) in order to ensure that the workpiece accuracy and surface finish coating or pressure embedded in the grinding plate of abrasive particles, refined by the relative motion of the grinding plate and the workpiece under a certain pressure on the machined surface Finishing and derived from a cast iron plate.
Grinding platform use:
Grinding plate for measuring the manufacture, repair, parts grinding, high precision mechanical parts production, the processing of optical instruments.
Research go to a very thin surface layer from the workpiece on grinding tools and abrasives, the workpiece accurately the size and shape and high surface quality, this processing method is called grinding. Grinding is a finishing process, he has broad applications in the tools, measuring tools and precision machinery manufacturing. With the development of machinery industry, grinding manual gradually tend to mechanization.
      Grinding plate: the grinding plate surface to be smooth, no cracks, spots and other defects; material generally with a gray cast iron, it has good lubricating properties, high grinding efficiency, and wear quite small. Particularly suitable for lapping.
Pressure sand flat panel Profile:
Pressure sand plate test a variety of precision parts of the surface (run out of gap method), and repair the flatness tools of the various gauge block, the card measuring, optical other and the measurement accuracy and other parts of the tool. Pressure sand flat panel as the repair of the amount of only measuring instruments, it is good or bad will have a direct impact on the amount of repair quality.
      Pressure sand flat panel: pressure sand flat-panel ultra-fine grinding, the workpiece with the tablet. Before grinding methods: grinding, fine abrasive evenly spilled between the two plates, then embedded in the work surface of the tablet tablet with each other on the research, the fine silt, constitute a certain firmness of "multi-edge research surfacing. After pressure sand tablet grinding, fine texture of the surface to get the exact size and high surface quality.
    The use of pressure sand flat FAQs:
    Uneven cutting: due to the uneven abrasive, the solution is to abrasive smooth evenly.
    Cutting scratch law: natural Whetstone destroyed coarse sand got into the coarse sand.
    The surface color is yellow: the flat surface is no longer the cutting force, the method is to re-pressure sand.
    Irregular scratches: the method of cleaning the surface of the flat surface debris mixed with gasoline dilution, less coated with a drop of stearin.
