平板是用于工件检验和划线的平面基准器具。这一定义表明了平板的功能、性质、用途。
1、平板是以固定形式复现量值的器具，他是实物量具。
2、平板工作面常作为平面基准，用来校对和调整其他测量器具或作为标准与被测件进行比较，专门用于形位误差的测量。因为他是形位误差的测量器具。
3、平板命名的同时指出了具体用途——用于工具的检测和划线。较大规格的的平板安装在专用支架上时，统称为平台。
平板的种类按其材质分为钢制平板、铸铁平板和岩石平板；按其结构，铸铁平板分为筋板式和箱体式；岩石平板分为有凸缘式和无凸缘式；按其用途分为检验平板、划线平板和压砂平板；按其准确度级别分为00，0，1，2，3级平板，其中2级以上为检验平板，3级为划线平板。这样的划分进一步保证了高精度平板的工艺性能和内在质量。
平板在检测中一般用作基准定位面。检验平板是用于涂色法检验工件表面平面度，或作为检测工作的辅助工具。划线平板适用于划线工作。钢制平板一般用作冷作放样或样板修整，研磨平板作为研磨工具加工超精表面。
A Brief Description of the Types and Uses
of T-grooved Plates
Flat plate is a plane benchmark used for
workpiece inspection and marking. This definition indicates the function,
nature and use of the plate.
1. The flat plate is an instrument that
reproduces the value of a quantity in a fixed form. It is a kind of measuring
instrument.
2. Flat face is often used as plane datum
to calibrate and adjust other measuring instruments or to compare with the
measured parts as a standard, which is specially used for the measurement of
form and position errors. Because he is a measuring instrument for form and
position errors.
3. While naming the tablet, it also points
out the specific use for tool detection and marking. When a larger plate is
mounted on a special bracket, it is collectively referred to as a platform.
The types of slabs are divided into steel
slabs, cast iron slabs and rock slabs according to their material quality;
according to their structure, cast iron slabs are divided into ribbed slabs and
box type; rock slabs are divided into flanged and non-flanged types; according
to their use, they are divided into inspection slabs, scribed slabs and
sand-pressing slabs; and according to their accuracy level, they are divided
into 00, 0, 1, 2 and 3 levels. Plates, of which more than 2 are inspection
plates and 3 are scribed plates. This division further ensures the
technological performance and intrinsic quality of high precision flat plate.
Flat plate is generally used as a reference
plane in detection. Inspection plate is used to inspect the flatness of
workpiece surface by coloring method or as an auxiliary tool for inspecting
work. The marking plate is suitable for marking work. Steel plate is generally
used for cold lofting or sample dressing, and grinding plate is used as
grinding tool to process super-precision surface.
