Optimization of Casting and Machining Process of Brake Disks to Reduce Customer Rejects

Today most of automotive producers use brake disk in front axial. So it is one of the most safety parts in automotive industry. Because of special characteristics such as good heat transfer, damping capacity, and good machinability, Gray cast Iron is common material for making brake disks. This research, involve more than 20 years experiences in casting, heat treatment and machining of brake disks in Iranian companies. One of very important cases in decrease of driving quality is evades geometrical tolerances such as run-out, parallelism, etc in machining process. Another case is evades balance descended mold mismatch in casting process. These cases motivate wheel shake during driving or brake application. Therefore in this research, the machining of brake disk by best method in production process, for access the best quality and stability production process is reviewed.
