The appearance of the basic flat plate is basically a box type. The working surface is rectangular, square or round. The material is H and the scraping process is used. The working surface can be processed into shapes, U-shaped grooves, dovetail grooves, round grooves, etc. Holes, long holes, etc. It is a flat reference measuring tool used for workpiece and equipment inspection, marking, assembly, welding, assembly and riveting.
Basic flat plate specifications: **, (special specifications are made according to the buyer's drawings), the implementation standard is.
Basic plate accuracy: tested by coloring method. The grade-level flat platform shall be no less than 1 point within the range of mm square on each side. The grade-level flat platform shall be no less than 0.0 points within the range of ㎜ square on each side. The grade-level flat platform shall be no less than 0.0 points within the range of ㎜ square on each side. Points are that the working surface of the cast iron platform should be free of rust, scratches, bruises and other appearance defects that would affect use.
The basic platform (basic flat plate) is suitable for various assembly, welding, and inspection work. It is a reference plane for accuracy measurement. It is used for machine tool mechanical assembly, inspection and measurement reference, checking the dimensional accuracy or behavioral deviation of parts, and making precision measurements. Assembly, welding, and marking are also indispensable basic tools in mechanical manufacturing.
After using the basic platform, clean the working surface in time and then apply a layer of anti-rust oil.
The basic platform (basic flat plate) is subject to regular weekly inspections in accordance with national standards, and the verification cycle can be several months depending on the specific situation.
Basic platform (basic flat plate) packaging: wooden packaging form, the platform surface is sealed with plastic film, this kind of packaging is suitable for inland transportation of the flat plate, and has good moisture-proof, shock-proof, rust-proof and rough handling resistance, etc. Measures to protect the platform to ensure safe delivery to site.
After the basic platform (basic flat plate) is worn out, it can be re-scraped to restore its accuracy.
The basic platform (basic flat plate) can be used to test the flatness of parts using the coloring method, which has the advantages of accuracy, intuition and convenience. Pushing the watch base and workpiece on the scraped cast iron flat plate is smoother and has no astringent feeling, which facilitates measurement and ensures measurement accuracy.
The cast iron quality and heat treatment quality of the basic platform (basic flat plate) have a great impact on the performance of the flat plate: either the working surface is deformed due to large residual internal stress, the accuracy cannot be maintained due to lack of wear resistance, or it is difficult to scrape. Roughness with small values cannot be obtained.
