The working surface of the Beizhong manufacturer's fireworking platform adopts the scraping process, and V-shaped, T-shaped, U-shaped grooves, dovetail grooves, round holes, long holes, etc., can be machined on the working surface. The fireworking platform is a flat reference measuring tool used for workpiece inspection or marking. The fireworking platform is manufactured according to the JB/T7974-1999 standard. The products are made in ribbed plate and box-type structures, with working surfaces in rectangular, square, or circular shapes. The materials used are HT200-300, QT400-600, and ZG15-45. The working surface of the fireworking platform adopts the scraping process, and V-shaped, T-shaped, U-shaped grooves, dovetail grooves, round holes, long holes, etc., can be machined on the working surface. The platform is a flat reference measuring tool used for workpiece inspection or marking. The fireworking platform (fireworking plate) should be installed and adjusted to a horizontal position, with the load evenly distributed across all support points. The ambient temperature should be (20±5)°C. Vibration should be avoided during use. The fireworking platform must have a flat appearance, accurate dimensions, and be free of internal defects. It must possess sufficient strength and stiffness to withstand the impact force of fireworking hammers and meet the needs of fireworking production. Fireworking Platform Parameter Description

1. Fireworking platform specifications: 100*100--3000*6000mm (special specifications can be customized according to drawings as needed). 2. Fireworking platform uses: Suitable for various inspection tasks, serving as a reference plane for precision measurement, used as a measurement reference for machine tool mechanical inspection, checking, and for measuring dimensional accuracy or geometric deviations of precision parts. It is also used for precision marking and is an indispensable basic tool in mechanical manufacturing. 3. Fireworking 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 it has good wear resistance. 4. Execution standard: Manufactured according to the JB/T7974-1999 standard, with accuracy following the national standard metrological verification regulation JJG117-91.
