Introduction to machine tool castings:
The machine tool stand is one of the machine tool castings. The production of the machine tool stand requires not only the use of advanced and reasonable casting processes and equipment, but also the casting structure itself to meet the requirements of casting production. The rationality of the casting structure for the casting process is called the "casting processability" of the machine tool casting.

Machine tool casting method: The casting method is usually sand casting, followed by special casting methods, such as: metal casting, investment casting, gypsum casting, etc. Sand casting can be divided into clay sand type, organic binder sand type, resin self-hardening sand type, lost mold and the like.
Principles for selection of machine tool casting methods:
1. Sand casting is preferred. The main reason is that sand casting has lower cost, simple production process and shorter production cycle than other casting methods. When the wet type does not meet the requirements, consider using a clay sand table dry sand type, dry sand type or other sand type. Clay wet sand castings can weigh from a few kilograms up to tens of kilograms, while clay dry castings can weigh up to tens of tons.
2. The casting method should be compatible with the production batch. Casting methods such as low pressure casting, die casting, and centrifugal casting are only suitable for mass production because of the high cost of equipment and molds.

3. The modeling method should be suitable for the factory conditions. For example, it is also the production of castings such as large machine bed, generally using the core forming method, not making the pattern and the sand box, and assembling the core in the pit; while the other factory adopts the sand box modeling method to make the appearance. Different enterprise production conditions (including equipment, site, staff quality, etc.), production habits, and accumulated experience are different. It should be considered according to these conditions what products are suitable and what products are not suitable (or not).
4, taking into account the precision requirements and costs of castings.
