When it comes to "5-axis simultaneous and 5-axis positioning processing", I suddenly found that these two words sometimes confuse many people in the processing industry. Simply put, most of the tasks in current processing can be completed with 3 axes. Yes, a rough estimate of 85%. Only the remaining 15% need to use 5-axis machining, and 3+2 machining in 5-axis machining accounts for at least 80% of this 15%, that is, 12% of the total, and only the remaining 3% need to use 5 The 5-axis simultaneous processing here includes the 4-axis simultaneous situation. The main processed parts are impellers, blades, aviation thin-walled parts, and a few industrial design products.

The principle of 3+2 positioning machining is essentially the realization of the 3-axis function at a specific angle (that is, "positioning"). Simply put, when the machine tool rotates the angle, it is still processed in the normal 3-axis way. It is suitable for most of the mechanical parts, such as the processing of automobile gear box and engine housing, etc.
