Everyone knows that five-axis machine tools are expensive, but do you know the core value of five-axis?

Why do more and more manufacturers tend to use five-axis equipment to meet high-quality processing requirements? Let's take a look together today.

5-AXIS has value

The update cycle of new products has been shortened, costs have been forced to decrease, and traditional processes cannot meet the delivery requirements. The quality and quantity of the products rely on labor, and the labor cost is getting higher and higher. Electrical discharge machining requires the processing of electrodes, which has high process costs, low efficiency, poor quality and can be replaced by five-axis machining. The maturity of three-axis machining technology has led to fierce homogeneous competition. In the homogenized competition, only unique core technologies or doing work that others cannot do can stand out. All these have given rise to the emergence of five-axis machining.

Five-axis characteristics

A five-axis machining center is based on a three-axis system and adds two of the rotating axes, A, B, and C. Its distinctive feature lies in the interlocking relationship between the two added rotating axes and the linear axis as well as its structure. The five-axis linkage makes the processing efficiency faster. The tiltable C-axis structure has larger bearings and better rigidity.

The core value of the five axes

No.1 accuracy

For some complex multi-faceted processing products, it is rather difficult to achieve high precision in three-axis processing, and the manual intervention time is relatively long. However, five-axis machining can achieve rapid positioning machining, mainly increasing the machining accuracy of products from the following aspects:

1) Introduce the five-axis fixture;

2) Reduce the clamping process;

3) There is no need for manual multiple clamping, and the clamping error is reduced.

4) Only one coordinate system needs to be found, reducing human errors.

5) Reduce the length-to-diameter ratio of the cutting tool to decrease the risk of tool springback.

For example, in the five-axis machining of mold sliders, the number of processes has been reduced from 13 to 2.

No.2 Surface quality

Five-axis can improve the surface processing quality of workpieces from the following perspectives:

1) Use tools with a relatively short length-to-diameter ratio to enhance processing stability;

2) The process of reducing discharge makes the entire surface more uniform;

3) Use the side edge of the ball cutter for processing to improve the surface quality of the workpiece.

No.3 Efficiency

Five-axis can enhance the processing efficiency of workpieces from the following perspectives:

1) Use tools with a relatively short length-to-diameter ratio to increase the feed rate during processing;

2) The process of using five-axis linkage processing to reduce discharge;

3) Use the side edge of a ball cutter for machining and use multi-edge tools to increase the feed rate for machining.
