With the development of the times, the precision requirements for workpieces and aluminum forgings in industrial production are getting higher and higher. Ordinary rough machining is difficult to meet the personalized needs of different customers. Therefore, in the process of making forgings, most processing plants often have semi finishing and finishing steps after preliminary processing, which will greatly increase the precision of the workpieces produced and improve the comprehensive competitiveness of enterprises. So what exactly is finishing? What are the finishing techniques for forgings?
First of all, we want to solve your questions, because many new friends in this industry do not know what is finishing, and why there is a distinction between primary processing and finishing.
The so-called forging finishing is a process of making the main surface meet the requirements of the drawing by using special tools to process the semi-finished products of the workpiece more finely. In actual operation, for parts with no precision requirements, only rough machining can be used to obtain finished products; For parts with high accuracy requirements, machining allowance shall be reserved in rough machining for further finishing.
Why can't it be formed at one time, but must separate the initial processing from the finishing? This is because many workpieces are rough, the shell is hard and the end face is irregular. If these blanks with different materials and different hardness are finished directly, the tool will be easily damaged, which will not only increase the processing cost but also affect the processing accuracy.
