Marking platforms and marking plates are manufactured according to standards

Marking platform
/The cast iron platform is manufactured according to the / standard. The marking platform
is made into stiffened plate type and box type. The working surface is rectangular. The material is scraped and ground. The surface can be processed with shapes, shapes, grooves, round holes, long holes, etc. The cast iron flat plate is a flat reference instrument used for workpiece inspection or marking. The installation of the flat plate should be adjusted to the level, and the load should be evenly distributed on each fulcrum. Vibration should be avoided when using it at ambient temperature. The purpose of the flat plate (platform) is to check the flatness, straightness and other geometric tolerances of machine parts as a measurement benchmark. It can also be used Parts marking and grinding processing, installation of equipment, etc. It is a measurement benchmark for testing geometric tolerances such as plane, parallelism and straightness of mechanical parts. It can also be used for scribing, riveting, welding and grinding process processing and measurement of general parts and precision parts. The production process of the marking platform
is basically as follows: 1. Make drawings of cast iron slab blanks according to technical requirements, make models according to the drawings, ingredients, modeling, drying, casting, falling sand, cleaning, and inspection of the blanks Each part of the blank is heat treated and aged. The purpose is to reduce the stress inside the casting and prevent deformation after machining. 2. Cast iron flat plate
Machining appearance inspection and marking, processing and inspection 3. Cast iron flat plate workpiece leveling, manual scraping and grinding, inspection by the inspection department 4. Appearance treatment, painting, packaging and warehousing of the cast iron flat plate. The accuracy of cast iron flat plates can also be said to be the flatness of cast iron flat plates. The general accuracy of cast iron flat plates can be divided into grades, grades, grades and grades. The accuracy standards of cast iron flat plates can be found in the "Machinery Industry Standards of the People's Republic of China"/. The selection of accuracy standards generally depends on the usage conditions. Cast iron flat plates with a precision above grade 1 are used for inspection, marking, assembly, etc. Cast iron flat plates with a precision below grade 1 are generally used for riveting and welding.
