鑄鐵平臺的刮研技術(shù)介紹

1、刮花

刮花的作用一是美觀(guān)，二是有積存潤滑油的功能。一般常見(jiàn)的 花紋有：斜花紋、燕形花紋和魚(yú)鱗花紋等。另外，還可通過(guò)觀(guān)察原花紋的完整和消失的情況來(lái)判斷平面工作后的磨損程度。

2、粗刮

若工件表面比較粗糙、加工痕跡較深或表面嚴重生銹、不平或扭曲、刮削余量在0.005mm以上時(shí)，應先粗刮。粗刮的特點(diǎn)是采用長(cháng)刮刀，行程較長(cháng)（10mm~15mm之間），刀痕較寬（10mm），刮刀痕跡順向，成片不重復。機械加工的刀痕掛除后，即可研點(diǎn)，并按顯出的高點(diǎn)刮削。當鑄鐵平臺表面研點(diǎn)每25mm×25mm上為4~6點(diǎn)并留有細刮加工余量時(shí)，可開(kāi)始細刮。

3、細刮 
細刮就是將粗刮后的高點(diǎn)刮去，其特點(diǎn)是采用短刮法（刀痕寬約6mm，長(cháng)5mm~10mm），研點(diǎn)分散快。細刮時(shí)要朝著(zhù)一定方向刮，刮完一遍，刮第二遍時(shí)要成45度或60度方向交叉刮出網(wǎng)紋。當平均研點(diǎn)每25mm×25mm上為10~14點(diǎn)時(shí)，即可結束細刮。

4、精刮 
在細刮的基礎上進(jìn)行精刮，采用小刮刀或帶圓弧的精刮刀，刀痕寬約4mm，平均研點(diǎn)每25m×25m上應為20~25點(diǎn)，常用于檢驗工具、精密導軌和緊密工具接觸面的刮削。

鑄鐵平臺是檢查機器零件平面度，直線(xiàn)度等形位公差的測量基準，也可用于零件劃線(xiàn)研磨加工，安裝設備等用途。是檢驗機械零件平面、平行度、直線(xiàn)度等形位公差的測量基準，也可用于一般零件及精密零件的劃線(xiàn)、鉚焊研磨工藝加工及測量等。 

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.
