详细信息

Inspection surface plate is usedas the main datum for measurement of the machinery parts’ geometrictolerance,such as flatness, parallelism, straightness and more. It is also canbe used for precision inspection, marking out (layout), and tooling setup. TheInspection surface plate is often used as the reference plane and baseline forall measurements to the workpiece and often used with straight Edge, SquareBlocks, V Blocks, Angle Plates, Parallel. etc.

检验平板材质：高强度铸铁HT200-300。校验平板经过人工热时效处理后,完全去除内应力，精度稳定，耐磨性能好。

工作面硬度：HB170-240。

Material:

High-strength cast ironHt200-300. After artificial heat aging treatment, the internal stress wastotally eliminated, so the surface plate have stable accuracy and good wear-resistingperformance.

检验平板流水作业 1、检验平板毛坯：按技术要求制图纸、按图纸制作木型、配料、造型、烘干、浇铸、落沙、清理、检验毛坯的各部位；

2、检验平板毛坯回火，达到消除铸造内应力的目的。

3、检验平板上机床、按图纸要求加工、送检验科检验；

4、检验平板粗加工后回火，达到消除加工内应力的目的。

5、检验平板工件调平、人工刮研、检验科检验；

6、检验平板的外观处理、喷漆、包装、入库

Producing Procedure ofInspection Surface Plate:

1. Rough casting:

Make drawings according to the technicalrequirements-Making mold as per the drawings-Prepare material-Modelling-Fillingsand-Drying-Casting-Surface cleaning -Casting parts testing.

First time Heat treating toeliminate the internal stress

3. Rough machining:

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

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

5. Precision finishing:

Leveling -Scraping- Finalinspection and testing.

6 .Final finish:

Painting- Packing-deliver towarehouse.

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