T型槽平板的一般验收条件

1、观察T型槽平板工作面不得有严重影响外观和使用的砂孔、气孔、裂纹、缩松、划痕、碰伤、锈点等缺陷。
2、合格的T型槽平板的表面应清除型砂且平整，涂漆牢固。
3、精度等级为0级-3级的T型槽平板工作面上，直径小于15mm的砂孔允许用相同材料堵塞，其硬度应小于周围材料的硬度。工作面堵塞的砂孔应不多于4个，且砂孔之间的间距应不小于80mm。
4、T型槽平板应采用优质细密的灰口铸铁或合金等材料制造，其工作面硬度应达到170-220HB。
5、T型槽平板工作面通常应采用刮削工艺。对采用刮削加工的3级T型槽平台工作面，其表面粗糙度Ra的最大允许值为5um。
6、采用刮削工艺应进行涂色对研检验。对研后显示的接触点面积的比率见表3的规定：或者按25mm×25mm正方形面积的接触点数见表3的规定，且任意25mm×25mm中的接触点数之间应不大于5点。
T型槽平板的一般验收条件

1）毛坯:按技能需求制图纸、按图纸制造木型、配料、外型、烘干、浇铸、落沙、整理、检验毛坯的各部位。

2）机械加工:外观检验并划线、加工、检验。

3）工件调平、人工刮研、检验科检验。

4）外观处理、喷漆、包装、入库。

1. Observe that the T-slot plate working surface must not have defects such as sand holes, pores, cracks, shrinkage, scratches, bumps, rust spots, etc. that seriously affect the appearance and use.
2. The surface of the qualified T-slot plate should be cleaned of sand and flat, and painted firmly.
3. The sand hole with a diameter of less than 15mm is allowed to be blocked with the same material, and the hardness should be less than the hardness of the surrounding material. There should be no more than 4 sand holes in the working face, and the spacing between the sand holes should be no less than 80mm.
4, T-slot plate should be made of high-quality fine gray cast iron or alloy, and its working surface hardness should reach 170-220HB.
5, T-slot plate working surface should generally use the scraping process. For the working surface of the 3-stage T-groove platform with scraping, the maximum allowable surface roughness Ra is 5um.
6, the use of the scraping process should be carried out color test. The ratio of the contact point area displayed after grinding is as specified in Table 3: or the number of contact points in a square area of 25 mm × 25 mm is shown in Table 3, and the number of contact points in any 25 mm × 25 mm should be no more than 5 points.
General acceptance conditions for T-slot plates
1) Blank: According to the skill requirements, make drawings, make wood type, batching, appearance, drying, casting, sanding, finishing and inspection of various parts of the blank according to the drawings.
2) Machining: Appearance inspection and scribing, processing, inspection.
3) Workpiece leveling, manual scraping, and inspection of the inspection department.
4) Appearance treatment, painting, packaging, storage.
