Cast iron platform included

Material: cast iron plate using HT200-300 casting, material ingredients ingredients and ingredients according to the following criteria (%): carbon: 3.1-3.4, manganese: 0.6-0.9, silicon: 1.5-2.0, sulfur <0.12, phosphorus < 0.3. Hardness> 180, the second tempering treatment.

By country Cast iron inspection platform The latest standard GB / T 22095-2008, respectively, 1, 2, 3, fine planing. Face with scraping research process, with the color method for testing, scraping on the use of three flat surface, the surface roughness Ra of the maximum allowable value of 5um. To ensure the accuracy of the plane.

Test platform material: Hardness of working surface HB140 --- 210.

Test platform technical requirements: Flat surface should not seriously affect the appearance and performance of the sand holes, pores, cracks, slag, shrinkage, scratches, bumps, rust and other defects.Plates the casting surface should be removed sand and smooth, The acute angle repair blunt.

First, the cast iron platform scratches

Scratch the role of one is beautiful, and second, there is the function of accumulated lubricants are generally common pattern: diagonal pattern, Yan-shaped patterns and fish scales, etc. In addition, the original pattern can also be observed by the integrity and disappearance of the situation to determine Plane work after the degree of wear.

Second, the cast iron platform rough scraping

If the surface roughness, deep processing of the surface or the surface of serious rust, uneven or twisted, scraping allowance of 0.005mm or more, the rough should be rough scraping coarse scraper is characterized by the use of long scraper, long travel (10mm ~ 15mm (10mm), scraper trail forward, into a piece does not repeat the mechanical processing of the marks in addition to hang, you can research point, according to the high point of shaving scraping.When the surface of cast iron platform research Point every 25mm × 25mm on the 4 ~ 6 points and leave a small scraping allowance, you can start fine scraping.

Cast iron platform fine scraping

Fine scraping is to scrape the rough after scraping the high point, which is characterized by a short scraping method (knife marks width of 6mm, length 5mm ~ 10mm), grinding points scattered fast. Once again, scraping the second time to 45 degrees or 60 degrees to cross the direction of cross-scratching.When the average research point every 25mm × 25mm for 10 ~ 14 points, you can end the fine scraping.

Cast iron platform fine scraping

In the fine scraping on the basis of fine scraping, using a small scraper or with a circular scraper, knife marks width of 4mm, the average research point every 25m × 25m should be 20 to 25 points, commonly used in inspection tools, precision guide rails and Scrape of the tight tool contact surface.
