Turning machining CNC turning aluminum parts is a method of cutting aluminum workpieces on a lathe using CNC turning aluminum parts relative to the rotation of the tool to produce CNC turning aluminum parts. The cutting energy of turning is mainly provided by the workpiece rather than the tool. CNC turning of aluminum parts is the most basic and common cutting method, and it occupies a very important position in production.

l The history of turning
l processing method
CNC turning aluminum parts is developed with the history of turning technology. In 1797, British mechanical inventor Mozley created a modern lathe that uses a screw to drive the tool post. In 1800, it adopted an exchange gear to change the feed speed and the pitch of the processed thread. In 1817, another Englishman, Roberts, used a four-stage pulley and back-wheel mechanism to change the spindle speed. This is the earliest technology for producing CNC turning aluminum parts
The production of CNC turning aluminum parts improves the degree of mechanization and automation. In 1845, Fitch in the United States invented the turret lathe. In 1848, there was a back-wheel lathe in the United States, but there was no CNC turning aluminum parts. At the beginning of the 20th century, a lathe with a gearbox driven by a separate motor appeared, and CNC turning aluminum parts slowly appeared in industrial production. After the First World War, due to the needs of the munitions, automobiles, and other machinery industries, various high-efficiency automatic lathes and specialized lathes for the production of CNC turning aluminum parts developed rapidly. To improve the productivity of small-batch CNC turning aluminum parts, in the late 1940s, CNC turning aluminum parts production lathes with hydraulic profiling devices were promoted. At the same time, multi-tool lathes producing CNC turning aluminum parts were also developed. In the 1950s, program-controlled lathes with punched cards, latch plates, and dials were developed. Numerical control technology began to be used in lathes in the 1960s, and the technology for producing CNC turning aluminum parts slowly developed into what it is today. The production of CNC turning aluminum parts has developed rapidly after the 1970s.
CNC turning aluminum parts are processed by precision turning. The main task of finishing machining is to ensure the machining accuracy and surface quality required by CNC turning aluminum parts. The outer surface of the finish turning generally adopts a smaller back-cutting amount and feed rate and a higher cutting speed to process CNC turning aluminum parts.
Fine-tuning is characterized by an extremely small back-cutting amount and feed amount, and the cutting speed of CNC turning aluminum parts is as high as 150-2000m/min. Fine turning generally uses cubic boron ammonia (CBN), diamond, and other superhard material tools to process CNC turning aluminum parts. The machining accuracy and surface roughness of fine turning are roughly equivalent to those of ordinary cylindrical grinding, and the machining accuracy can reach IT6 or more. , The surface roughness Ra can reach 0.4～0.005μm. It is mostly used for precision machining of non-ferrous metal workpieces with poor grinding workability. It is more effective for CNC turning aluminum parts of aluminum and aluminum alloy workpieces that are easy to block the pores of the grinding wheel.
