What is the difference between 3-axis, 4-axis and 5-axis CNC machining?

In the field of CNC machining, we often hear terms such as 3-axis, 4-axis, and 5-axis simultaneous machining. Specifically, what are the differences between them? Jiahangaero will briefly describe the differences between them in the text.

CNC milling machines are classified according to the number of axes they operate. These axes can basically determine what kind of parts can be manufactured, and the number of axes is also related to the accuracy and production efficiency of production. In general, the more axes available, the more complex parts it can produce.

① 3-axis CNC machining

3-axis CNC machining generally refers to three linear motion axes in different directions, such as up and down, front and back, left and right. The 3-axis can only process one surface at a time, which is more suitable for the price of some disk parts, and there are certain restrictions on the need to process holes or grooves on many surfaces.

② 4-axis CNC machining

The price of 4-axis CNC is to add a rotation axis on the basis of 3-axis, generally 360-degree rotation in the horizontal plane, but it cannot achieve high-speed rotation, it is more suitable for processing some box-like parts, most 4-axis CNC The machine tool allows the part to rotate, which is called the B axis in the industry. In this way, the equipment can act as both a milling machine and a lathe. If drilling is required on the side of a part or on the curved surface of a cylinder, 4 The shaft is a better choice, which obviously increases the efficiency of machining and can also improve the accuracy of machining.

③ 5-axis CNC machining

5-axis CNC machining is a rotation axis added to the 4-axis, generally 360-degree rotation on the vertical surface, the price of 5-axis CNC has been able to carry out comprehensive processing to achieve one-time clamping to complete all processing procedures, reducing the cost of clamping and products bruising rate. Because 5-axis CNC machining has higher versatility, it is more suitable for machining parts with more complex appearance and structure, such as prosthetics, medical components, aviation components, titanium alloy parts, engine parts and military products.

If you have the needs of machining parts, which type of CNC machining should you choose? First of all, we need to know that what is suitable is the best. We have to consider from many aspects. If our precision requirements are not so large, or our processing technology is not very complicated, then choosing three-axis can meet our needs. , and can also reduce some costs. If we need tolerance requirements within ±0.001mm or even smaller, then we can choose four-axis or five-axis. Of course, we must also consider the manufacturer's capabilities and listen to the manufacturer's opinions. Jiahangaero specializes in aluminum alloy precision manufacturing. It has more than 120 sets of 3-axis, 4-axis, and 5-axis CNC machines. It can provide you with professional CNC processing services. It has large output, small tolerances, and rich experience.
