It is not difficult for us to find that the alloy steel castings after grinding have been effectively improved not only in terms of quality but also in terms of performance, so it must be polished when producing castings, so what is the method?
1. Grinding work is generally completed by various grinding machines. For mass-produced alloy steel castings, automatic or semi-automatic special belt grinders and milling machines can also be used to form a grinding line to complete the grinding work. Commonly used belt sanders are fixed, suspended and portable.
2. Fixed grinding wheels are more commonly used, but since the castings need to be held by hand, they can only be used to polish small castings. Suspended grinder is suitable for grinding medium and large alloy steel castings in mass production. It can be pushed to various parts of the casting that need to be polished within a certain range.
3. The materials used to make grinding wheels are mainly silicon carbide and alumina. Grinding wheels made of silicon carbide for belt grinders are often used to grind harder castings, such as brass or bronze. Grinding wheels made of alumina for grinding softer steel castings or annealed malleable iron castings.
The above mainly introduces the grinding method of alloy steel castings. Although the grinding work is not difficult, it is related to various problems. We must do a good job of grinding, and only in this way can the quality be effectively improved.
