The C/CK5260 consists of the following main components: table, table base, column, cross beam and vertical support. The main elements of the machine are made of HT250 cast iron using sand-resin casting technology. After casting and pre-treatment, the parts were subjected to artificial and vibration aging processes. The quality of casting is characterized by the absence of cracks, pores, shrinkage cavities and other defects. The casting has a stable structure after artificial aging, which ensures the reliability and durability of the machine during operation. The product quality certificate indicates the chemical composition of the molten cast iron, heat treatment data and a curve of temperature versus heat treatment time.
