Machining is the typical process used by metal casting machinery to eliminate excess material from centrifugal castings. Upon completion of the centrifugal casting, the casting usually contains surplus material in the form of surface imperfections, excess metal, or sprues and risers.
To eliminate these excess materials, the castings are moved to a machining station where diverse cutting tools are utilized to shape and refine the casting according to the desired specifications. The specific machining operations employed depend on the design and requirements of the casting, but common techniques include turning, milling, drilling, and grinding.
Turning is frequently employed to get rid of excess material from the outer surface of the casting, thereby creating a smooth and uniform finish. Milling and drilling operations may be utilized to create intricate features or holes in the casting, while grinding is often used to enhance the surface finish and eliminate any remaining imperfections.
Advanced metal casting machinery may also incorporate computer numerical control (CNC) technology, which enables precise and automated machining operations. CNC machines are capable of following pre-programmed instructions to eliminate excess material with high accuracy, ensuring consistent quality across multiple castings.
In certain cases, additional processes such as heat treatment or surface finishing might be conducted to further improve the properties and appearance of the castings. These processes are typically carried out once the initial machining stage is completed.
Overall, metal casting machinery undertakes the task of removing excess material from centrifugal castings through machining operations, ensuring that the castings meet the required specifications and quality standards.
Metal casting machinery typically handles the removal of excess material from centrifugal castings through a process known as machining. After the centrifugal casting is completed, the casting is typically left with excess material in the form of surface imperfections, excess metal, or sprues and risers.
To remove these excess materials, the castings are transferred to a machining station where various cutting tools are used to shape and refine the casting to the desired specifications.

Metal casting machinery typically handles the removal of excess material from centrifugal castings through a process known as centrifugal cleaning. Once the casting has solidified, it is removed from the mold and placed in a centrifuge chamber. The chamber is then spun at high speeds, causing the excess material, such as gates, risers, and flash, to be forced outwards due to centrifugal force. This excess material is then collected and separated from the casting, leaving behind a clean and finished product.
