Calibration plate is also called: school tube plate, shipbuilding calibration plate , heavy calibration plate , calibration plate specially is used in the welding of large equipment tablet (platform), with reasonable design, stable structure, high precision, wear resistance, etc, which can realize3000 mm- 6000 - mm plate joining together, the product is made by scraping or grinding.Calibration plate is widely used in machining, tool workshop, machine shop, large equipment base, measuring room and precision processing of inspection, measuring and grinding, and the exact measurement,  testing the flatness of workpiece, flatness and Angle tolerance values.

校管平台 除具有普通必备的性能外，还有别具一格的优质特性：

第一、容易得到量块所需的较高光洁度和研合性,工件镜面青亮。

第二、用较简单的方法即可使平台上砂，且上砂快,嵌砂量足，经过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。

第三、校管平台不仅耐用，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。

Calibration plate beside has the general performance, and has also a unique style of high quality features:

    Firstly,It is easy to obtain degree of finish and grinding.

Secondly,the simpler method can make the platforms and the sand,quick sand,sand amount,after using it can still use similar sand,polished finish after improved significantly.

Thirdly, calibration plate is not only durable ,cutting and resistance,after light guide sand ,it  has good machinability,pushing grind smoothly.
