CNC Knowledge: Everyone knows that five-axis machine tools are expensive, but do you know the fundamental value of five-axis?

As five-axis linkage machining centers are increasingly used in various fields, topics related to five-axis machining are increasing. For example, why do more and more manufacturers tend to use five-axis equipment to ensure high-quality processing? Let’s take a look today:

5 AXES have value

New product update cycles are shortened, costs must be reduced, and traditional processes cannot meet delivery requirements; the quality and quantity of products depend on labor, and labor costs are getting higher and higher; process costs, low efficiency and poor quality, the maturity of three-axis machining technology has led to fierce competition in homogenization.

In homogenous competition, only unique core technologies or work that others cannot do can stand out. This gave rise to five-axis machining.

Five-Axis Features

The five-axis machining center adds two rotary axes, A/B/C, to the three axes. Its characteristic lies in the connection relationship and structure of the two added rotary axes and the linear axis. Five-axis linkage accelerates processing efficiency. Tilting C-axis structure, larger bearings and better rigidity.

precision n°1

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

1) Introduction of a five-axis luminaire;

2) Reduce the tightening process;

3) There is no manual multiple tightening and the tightening error is reduced;

4) You only need to find the coordinate system once, reducing manual errors;

5) Reduce the tool length to diameter ratio and reduce the risk of tool tipping.

n°2 Surface quality

Five axes can improve the surface treatment quality of workpieces from the following perspectives:

1) Use tools with shorter length/diameter ratio to improve processing stability;

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

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

Five areas can improve the efficiency of parts processing from the following perspectives:

1) Use a tool with a shorter length/diameter ratio to increase the processing feed;

2) Use five-axis linkage processing to reduce discharge processes;

3) Use the side edge processing of the ball cutter and use the multi-edge tool to increase the processing feed.

From the first manually operated three-axis to CNC three-axis, and now to today’s high-precision five-axis, the development of five-axis is a trend and does not happen overnight.
