The partitions of the shell and tube heat exchanger need to be drilled and cut during the production process. A laser cutting machine is often required to cut the partitions. After cutting the partitions, the partitions need to be cut. Since the partitions are mostly hard and brittle materials, direct cutting is likely to cause damage to the materials. A laser cutting machine with a built-in cutting structure is required to ensure the stable discharge of the shell and tube heat exchanger partitions. Therefore, when workers cut the holes of the shell and tube heat exchanger partitions, they often need a laser cutting machine with a built-in cutting structure to improve the stable cutting of the partitions.
