With the application of five-axis machining centers in various fields more and more widely, there are more and more topics about five-axis machining. For example, why more and more manufacturers tend to use five-axis equipment to meet high-quality processing? Let's take a look today:
5-AXIS existence value
The new product update cycle is shortened, the cost is forced to be reduced, and the traditional process cannot meet the delivery requirements; the quality and quantity of the product depend on labor, and the labor cost is getting higher and higher; EDM needs to process electrodes, which has high process cost, low efficiency, and poor quality , Five-axis can be replaced; the maturity of three-axis processing technology has led to fierce competition for homogeneity.
In the homogeneous competition, only the unique core technology, or the work that others cannot do, can stand out. These have given birth to the emergence of five-axis machining.
Five-axis features
The five-axis machining center is based on the addition of two rotation axes of A/B/C on the basis of the three axes. It is characterized by the linkage relationship and structure of the added two rotation axes and the linear axis. Five-axis linkage makes the processing efficiency faster. Tiltable C-axis structure with larger bearings and better rigidity.

no.1 precision
For some complex multi-faceted processing products, it is difficult to achieve high precision in three-axis processing, and it takes a long time for manual intervention. However, five-axis machining can achieve rapid positioning machining, mainly from the following angles to increase the machining accuracy of the product:
1) Introduce a five-axis fixture;
2) Reduce the clamping process;
3) There is no manual multiple clamping, and the clamping error is reduced;
4) You only need to find the coordinate system once to reduce manual errors;
5) Reduce the length-to-diameter ratio of the tool and reduce the risk of knife snapping.

no.2 surface quality
The five-axis can improve the surface processing quality of the workpiece from the following angles:
1) Use a tool with a relatively short length and diameter to improve processing stability;
2) The process of reducing discharge makes the entire surface more uniform;
3) Use the side edge processing of the ball cutter to improve the surface quality of the workpiece.
no.3 Efficiency
The five-axis can improve the machining efficiency of the workpiece from the following angles:
1) Use a tool with a relatively short length and diameter to increase the machining feed;
2) Use five-axis linkage machining to reduce discharge;
3) Use the side edge machining of the ball cutter, and use the multi-blade cutter to increase the feed rate of the machining.

From the initial manual three-axis to CNC three-axis, to today's high-precision five-axis, the development of five-axis is a trend, and it does not happen overnight.
