What Are The Casting Methods For Machine Tool Castings?
Jun 15, 2018

The casting methods for machine tool castings.

 

1, Priority is given to sand casting. The main reason is that sand casting has lower cost, simpler production process, and shorter production cycle than other casting methods. When the wet type can’t meet the requirements, consider using a 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, whereas clay dry type castings can weigh up to tens of tons.

 

2, The casting method of machine tool castings should be compatible with the production batch. Low-pressure casting, die-casting, centrifugal casting and other casting methods are only suitable for mass production because the equipment and molds are expensive.

 

3, Modeling method should be suitable for factory conditions. For example, castings such as large-scale machine tool beds are generally produced by using a core assembly method. Patterns and sand boxes are not produced, and cores are placed in pits. In other factories, sand box modeling methods are used to make patterns. The production conditions, production habits, and accumulated experience of different companies are all different. Based on these conditions, we should consider what products are suitable and what products are not suitable (or cannot). The flatness of the machine tool bed casting can be divided into three levels: reference, master, and working room. It should be selected according to actual needs. The flatness test accuracy is a guarantee of the quality of the flat panel.
