檢驗平板是檢驗機械零件,平面度,平行度,直線度等形位公差的測量基準, 檢驗平板也可用于一般零件及精密零件的劃線,研磨工藝加工和測量等.檢驗平板是鑄鐵平板的一種，用于各種校驗工作，精密測量用的基準平面；用于機床機械檢驗測量基準；檢查零件的尺寸精度或形為偏差，并作緊密劃線，在機械制造中也是不可缺少的基本工具。檢驗平板是精密測量校正用的基準工作平面,與平尺、方箱、V型架（鐵）、彎板、直角尺、圓柱角尺等工具配合使用。

Inspection surface plate is used as the main datum for measurement of the machinery parts’ geometric tolerance,such as flatness, parallelism, straightness and more. It is also can be used for precision inspection, marking out (layout), and tooling setup. The Inspection surface plate is often used as the reference plane and baseline for all measurements to the workpiece and often used with straight Edge, Square Blocks, V Blocks, Angle Plates, Parallel. etc.

檢驗平板材質：高強度鑄鐵HT200-300。校驗平板經過人工熱時效處理后,完全去除內應力，精度穩定，耐磨性能好。

工作面硬度：HB170-240。

Material:

High-strength cast iron Ht200-300. After artificial heat aging treatment, the internal stress was totally eliminated, so the surface plate have stable accuracy and good wear-resisting performance.

檢驗平板流水作業 1、檢驗平板毛坯：按技術要求制圖紙、按圖紙制作木型、配料、造型、烘干、澆鑄、落沙、清理、檢驗毛坯的各部位；

2、檢驗平板毛坯回火，達到消除鑄造內應力的目的。

3、檢驗平板上機床、按圖紙要求加工、送檢驗科檢驗；

4、檢驗平板粗加工后回火，達到消除加工內應力的目的。

5、檢驗平板工件調平、人工刮研、檢驗科檢驗；

6、檢驗平板的外觀處理、噴漆、包裝、入庫

Producing Procedure of Inspection Surface Plate:

1. Rough casting:

Make drawings according to the technical requirements-Making mold as per the drawings-Prepare material-Modelling-Filling sand-Drying-Casting-Surface cleaning -Casting parts testing.

First time Heat treating to eliminate the internal stress

3. Rough machining:

Machining as per the drawing- Casting Parts’ inspection and test.

4. Second time Heat treating and aging treatment, to eliminate the internal stress

5. Precision finishing:

Leveling -Scraping- Final inspection and testing.

6 .Final finish:

Painting- Packing-deliver to warehouse.

The accuracy of the Cast Iron Surface Plate refers to the deviation from flatness of the working surface and it shall be classified as Grade 0,1,2,3.
