What Are The Technical Requirements For The Processing Of High Chrome Iron Sand Casting?

The technical requirements of the gravity casting in low price affect the working performance of the parts on the one hand and the economics and feasibility of the manufacturing process on the other hand. There are often technical questions about the processing of casting mold parts. The following is a simple analysis of this problem.

1. Surface dimensional accuracy of High Chrome Iron Sand Castingprocessing;

2. Part processing shape accuracy;

3. Surface roughness of the part;

4. The mutual positional accuracy between the machining surfaces of the parts;

5. The hardness and heat treatment requirements of the parts;

6. Other special requirements.

Usually, during the processing, as the surface precision is improved, it is inevitable that a finer surface roughness will be obtained at the same time, but as the surface roughness is lowered, the processing cost is increased. Therefore, when determining the accuracy, the operator must first ensure the performance requirements of the part, and also consider the process conditions and the manufacturing cost of the parts.
