Details of cast iron scraping research platform

Advantages of cast iron scraping and slabs: The working surface of cast iron slabs is good, the accuracy is high, and there is no jerky feeling. It has uniform structure, dense structure, no trachoma stomata, looseness and other defects.
Common knowledge of cast iron flat plate scraping technology:
What are flat, rough and fine scrapes?
Why should the cast iron flat work surface be scratched?
刮花有什么作用? What is the effect of cast iron scraping and screeding?
Rough scraping of cast iron: If the working surface of the flat plate is relatively rough, the machining marks are deep or the surface is severely rusted, the working surface is uneven or distorted, and the scraping margin is above 0.005mm, it should be rough scraped first. Coarse scraping is characterized by the use of a manual long scraper with a long stroke (between 10mm and 15mm), a wide blade mark (10mm), and a smooth blade trace that does not repeat into pieces. After the mechanically processed knife marks are scraped off, you can apply the diluted iron oxide red, grind the points with a flat ruler, and scrape according to the high point shown. When the grinding point on the surface of the workpiece is 4 to 6 points per 25㎡ × 25㎡ and there is a fine scraping machining allowance, fine scraping can be started.
Flat cast iron scraping and flat scraping: Flat scraping _ is to scrape off the high points after rough scraping. It is characterized by using the short scraping method (blade marks are about 6mm wide and 5mm ~ 10mm long), and the grinding points are dispersed quickly. When scraping finely, you should scrape in one direction, and then scrape it once. When scraping twice, you should scrape the net in a direction of 45 degrees or 60 degrees. When the average research point is 10-14 points per 25㎡ × 25㎡, the fine scraping can be ended.
Grade accuracy of cast iron scraping plate and scraping platform:
The level of cast iron slab requires no less than 20 points in any 25x25mm plane. The secondary cast iron plate requires that the number of contact spots is not less than 12 points in any 25x25mm plane. Tertiary scratching plates do not specify contact spot requirements.
Cast iron scraping and grinding flat plate fine scraping: Fine scraping is performed on the basis of fine scraping, using a small scraper or a fine scraper with an arc, the width of the knife mark is about 4mm, and the average grinding point should be 20-25 points per 25㎡ × 25㎡ , Usually used for scraping of inspection tools, precision guides and tight tool contact surfaces.
Cast iron flat plate scratching: Flat plate scratching is usually called cover surface. The effect of scratching is beautiful, and the function of accumulating lubricating oil. The common patterns are: diagonal pattern, dove pattern and fish scale pattern. In addition, by observing the completeness and disappearance of the original pattern, the degree of wear after flat work can be judged.
Material of cast iron scraping slab: High-strength cast iron HT200-300 Working surface hardness is HB170-240, after two manual treatments (artificial annealing 600-700 degrees and natural aging 2-3 years), the accuracy of this product is stable and wear-resistant Good performance.
Specifications of cast iron slabs: 100 × 100-3000 × 6000mm. Precision of cast iron slabs: According to standard measurement verification procedures, they are 0, 1, 2, 3 respectively.
