Inspection Workbench

Beizhong manufacturer's inspection workbench is also known as cast iron inspection platform, inspection cast iron workbench, inspection plate, large inspection cast iron plate, precision inspection cast iron plate, fitter inspection plate.
Inspection workbench material: HT200-300; Hardness of cast iron inspection workbench: HB170-240. The inspection workbench is mainly used for riveting, welding, inspection, testing, assembly, power machinery testing, and can also be used for marking, grinding process machining, and measurement of general parts and precision parts. The inspection workbench is also known as cast iron inspection platform, inspection cast iron workbench, inspection plate, large inspection cast iron plate, precision inspection cast iron plate, fitter inspection plate.
Detailed specifications of the inspection workbench:
1. Cast iron inspection platforms with specifications from 100mm*200mm to 400mm*400mm, with accuracy grades of 0, 1, and 2.
2. Inspection workbenches with specifications from 400mm*600mm to 1500mm*2500mm, with accuracy grades of 1, 2, and 3.
3. Cast iron inspection workbenches with specifications from 1500mm*3000mm to 2000mm*3000mm, with accuracy grades of 2, 3, or fine planing.
4. Inspection plates with specifications from 2000mm*4000mm to 3000mm*10000mm-4000mm*8000mm, with accuracy grade 3 or fine planing.
Inspection workbench casting process: 1. First, the sand milling process must be well controlled. The performance of the molding sand will directly affect the quality of the platform measuring tool castings. Therefore, the molding sand should have good permeability, wet strength, fluidity, plasticity, and yieldability.
2. Strictly follow the feeding sequence: old sand - new sand - clay - water. The mixing time is set at 6-7 minutes, and after mixing, it should be tempered for about 5 hours. Control of the casting pouring process. Before pouring, the molten iron should be treated with inoculation and slag removal.
3. During the pouring of inspection platform castings, use a large flow, pour steadily and continuously until full. In case of run-out, promptly block the leaking area and replenish molten iron to reduce defects such as cold shuts and insufficient pouring.
Control of the casting cleaning process for inspection platforms. The cleaning process involves removing the measuring tool castings from the mold after cooling to obtain surface-defect-free platform measuring tool castings. Select a reasonable gating system to allow sequential solidification of the measuring tool castings, resulting in uniformly structured measuring tool castings.
