The characteristics of precision casting
The characteristics of precision casting:
1. The larger boundary length of precision castings is 700Mm, which is easy to work under 200mm, and the larger net weight is about 100kg, usually less than 10kg.
1. The larger boundary length of precision castings is 700Mm, which is easy to work under 200mm, and the larger net weight is about 100kg, usually less than 10kg.
2. The standard tolerances of precision castings are 20mm ±0.13mm ±100mm ±0.30mm, 200mm ±0.43mm mm, but the specification accuracy of small parts is not easy to achieve within ±0.10mm. The tolerance of viewing angle dimension is ±0.5 ~ ±2.0 degrees, and the precision casting Z is less than 0.5 mm in thickness and 1.5 mm in thickness. The surface roughness of precision castings is about Rmax4s ~ 12s.
3. There are basically no restrictions on precision casting materials, such as nut lost foam ductile iron castings, spinning pituitary-water glass steel castings, titanium metal, alloy copper, flange water glass precision steel castings, cobalt-based and nickel-based heat-resistant alloys, hard raw materials.
4. Precision castings are made into complicated workpieces with excellent specification and precision, drilling production and processing.
5. Precision castings save the consumption of raw materials and can be manufactured in many ways.
