Mechanical processing stages are divided into divided into several stages?
mechanical processing generally divided into three stages, respectively is rough machining, semi-finishing and finish machining.
rough machining: with rapid removal of the blank allowance for the purpose, should be chosen when rough precision machining large feeding and cutting depth as large as possible, so that in a relatively short period of time to remove as much allowance.
finishing: make precision machining surface to achieve high precision and surface quality.
semi-finishing: between roughing and finishing in the middle of the process.
