The working surface of the North Heavy manufacturer's firework platform adopts scraping technology, and V-shaped, T-shaped, U-shaped grooves, dovetail grooves, round holes, long holes, etc., can be processed on the working surface. The firework platform is a flat reference measuring tool used for workpiece inspection or marking. The firework platform is manufactured according to the JB/T7974-1999 standard, and the products are made in ribbed plate and box-type structures. The worktable surface can be rectangular, square, or circular, with materials including HT200-300, QT400-600, and ZG15-45. The working surface of the firework platform adopts scraping technology, and V-shaped, T-shaped, U-shaped grooves, dovetail grooves, round holes, long holes, etc., can be processed on the working surface. The platform is a flat reference measuring tool used for workpiece inspection or marking. The firework platform (firework plate) should be installed and leveled, with the load evenly distributed on each support point. The ambient temperature is (20±5)°C. Vibration should be avoided during use. The firework platform must have a flat shape, accurate dimensions, and be free of various internal defects, with sufficient strength and stiffness to withstand the impact force of firework hammers, meeting the needs of firework production. Firework Platform Parameter Description

1. Firework platform specifications: 100*100--3000*6000mm (special specifications can be customized according to drawings as needed). 2. Firework platform uses: Suitable for various inspection tasks, serving as a reference plane for precision measurement, used as a reference for machine tool mechanical inspection and measurement, checking, and for determining the dimensional accuracy or geometric deviation of precision parts, as well as for precision marking. It is an indispensable basic tool in mechanical manufacturing. 3. Firework platform material: HT200-300, QT400-600, ZG15-45. The working surface hardness is HB170-240. After two treatments (artificial annealing at 600°C-700°C and natural aging for 2-3 years), the product's accuracy is stable, and its wear resistance is excellent. 4. Execution standard: Manufactured according to the JB/T7974-1999 standard, with accuracy following the national metrological verification regulation JJG117-91.
