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.

Fitter assembly of heavy cast iron table : Mainly used for large-scale equipment, the installation of the workpiece and the measurement of crossed. Basic flat, mostly single piece of small flat stitch made of high precision, simple splicing, unlimited size can be extended and other characteristics of the application of the basic flat More and more widely.

Fitter assembly heavy cast iron table Widely used in the construction industry, printing industry, hydraulic equipment, construction industry, railway locomotive, instrument production, electronics industry, petrochemical, automotive, ceramic industry, railway locomotive, and other fields.

Cast iron platform measuring purposes: for the reference plane for machine tool inspection test benchmarks, inspection, and precision parts for the dimensional accuracy or behavioral deviation, and for precision marking, in the machinery manufacturing is also an indispensable basic tool.

Fitter assembly heavy cast iron table Material and use: Material for the high-strength cast iron HT200, the face hardness HB170-220, after two manual processing (artificial annealing 600 ° -700 ° and natural aging 2 to 3 years) to make the product accuracy and stability, wear resistance Good, the following product materials and treatment are the same except for ductile iron.

Cast iron platform measuring accuracy: According to the national standard measurement verification procedures, respectively, 0, 1, 2, 3 four levels.

First, 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, should be rough scraper.Grager is characterized by a long blade, long stroke (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 the cast iron platform 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.

Cast iron platform It can also be used for the grinding of parts and the installation of equipment, etc. It is the benchmark for measuring the geometrical tolerance of machine parts such as plane, parallelism and straightness, Can also be used for general parts and precision parts of the line, Maohan grinding processing and measurement.
