铸铁平台的刮研技术介绍

1、刮花

刮花的作用一是美观，二是有积存润滑油的功能。一般常见的 花纹有：斜花纹、燕形花纹和鱼鳞花纹等。另外，还可通过观察原花纹的完整和消失的情况来判断平面工作后的磨损程度。

2、粗刮

若工件表面比较粗糙、加工痕迹较深或表面严重生锈、不平或扭曲、刮削余量在0.005mm以上时，应先粗刮。粗刮的特点是采用长刮刀，行程较长（10mm~15mm之间），刀痕较宽（10mm），刮刀痕迹顺向，成片不重复。机械加工的刀痕挂除后，即可研点，并按显出的高点刮削。当铸铁平台表面研点每25mm×25mm上为4~6点并留有细刮加工余量时，可开始细刮。

3、细刮 
细刮就是将粗刮后的高点刮去，其特点是采用短刮法（刀痕宽约6mm，长5mm~10mm），研点分散快。细刮时要朝着一定方向刮，刮完一遍，刮第二遍时要成45度或60度方向交叉刮出网纹。当平均研点每25mm×25mm上为10~14点时，即可结束细刮。

4、精刮 
在细刮的基础上进行精刮，采用小刮刀或带圆弧的精刮刀，刀痕宽约4mm，平均研点每25m×25m上应为20~25点，常用于检验工具、精密导轨和紧密工具接触面的刮削。

铸铁平台是检查机器零件平面度，直线度等形位公差的测量基准，也可用于零件划线研磨加工，安装设备等用途。是检验机械零件平面、平行度、直线度等形位公差的测量基准，也可用于一般零件及精密零件的划线、铆焊研磨工艺加工及测量等。 

Introduction to scraping technology of cast iron platform

1, scratching

The effect of scratching is aesthetics, and the second is the function of accumulating lubricating oil. Common patterns include: diagonal patterns, swallow patterns, and fish scales. In addition, the degree of wear after the plane work can also be judged by observing the integrity and disappearance of the original pattern.

2, rough scraping

If the surface of the workpiece is rough, the processing marks are deep or the surface is severely rusted, uneven or distorted, and the scraping allowance is above 0.005mm, it should be rough scraped first. The rough scraping feature is a long scraper with a long stroke (between 10mm and 15mm) and a wide knife mark (10mm). The scraper traces are smooth and the sheets are not repeated. After the machined tool marks are removed, the points can be ground and scraped at the high points shown. When the surface of the cast iron platform is 4 to 6 points per 25 mm × 25 mm and the fine scraping allowance is left, fine scraping can be started.

3, fine scraping

Fine scraping is to scrape off the high point after rough scraping. It is characterized by short scraping method (knife mark width about 6mm, length 5mm~10mm), and the grinding point is scattered quickly. When scraping finely, it is necessary to scrape in a certain direction, and scrape it again. When scraping the second pass, it is necessary to cross the web in a direction of 45 degrees or 60 degrees. When the average grinding point is 10 to 14 points per 25 mm × 25 mm, the fine scraping can be ended.

4, fine shaving

Fine scraping on the basis of fine scraping, using a small scraper or a fine scraper with a circular arc, the knife mark width is about 4mm, and the average grinding point should be 20~25 points per 25m×25m, which is often used for inspection tools, precision guide rails and Scratch the contact surface of the tool.

The cast iron platform is a measurement standard for checking the flatness and straightness of machine parts, and can also be used for part scribing and grinding, installation equipment and other purposes. It is a measurement standard for checking the geometrical tolerances of planes, parallelism, straightness, etc. of mechanical parts. It can also be used for scribing, riveting and grinding process and measurement of general parts and precision parts.
