Problems solved by technology
[0003] However, the current five-axis power head of the CNC milling machine has a complex structure and high cost. When in use, due to the large milling force, the milling force affects the stability of the five-axis power head, making the tool of the five-axis power head shake, which directly affects the performance of the CNC milling machine. Processing quality, and the five-axis power head itself does not have a knife device, so it is inconvenient to change the tool

Description
Technical field [0001] The invention relates to the technical field of numerical control milling machines, in particular to a five-axis power head of a numerical control milling machine suitable for processing pentahedrons. Background technique [0002] CNC milling machines are widely used in the field of mechanical processing. The more commonly used is plane processing. Some CNC milling machines are equipped with a five-axis power head on the ram, which expands the processing range of the tool, and can process arcs or polyhedrons, reducing the need for re-clamping. Times, thereby reducing machining errors. [0003] However, the current five-axis power head of the CNC milling machine has a complex structure and high cost. When used, due to the large milling force, the milling force affects the stability of the five-axis power head, causing the tool of the five-axis power head to shake, which directly affects the performance of the CNC milling machine. Processing quality, and the f...
