As we all know, the ordinary engraving machine has three axes, that is, the three axes XYZ, all the engraving machine at least three axes, CNC engraving machine is a few axes? There may be four or five or even six axes. Which six are they? There are three axes, XYZ, and ABC, the three axes of rotation. The axis around x is the A axis, Y corresponds to B, and Z corresponds to C. However, no matter how you process it, it can only be used once. Face processing, a face mounting. It is often called the five axis.
Here I look at the five axes, the advantages and disadvantages of the sculpture field.
Five-axis, from the price point of view, the hardware is very expensive, there are few matching software in the country, both refer to foreign software, and the road to the knife is quite troublesome, requires professional technical personnel to carry out engraving, which limits his extensive application. And the engraving speed is also very slow and cannot be batch-engraved. Most people will not consider the question of when these hundreds of thousands of things can be returned.
Let's talk about the four axes. Specifically, there is one more axis of rotation, which axis does not matter. Four-axis subdivision, there are four-axis three-linkage and four-axis four linkage, what does the linkage mean? In other words, up to several axes move at the same time. What is the effect of this? Of course, it has an effect on the engraving method. The more linkages, the more complex the method of calculating the knife path in the engraving process. However, the four-axis machine manufacturers generally say that there are multiple layers of meaning, which requires a customer friend to ask to understand, or will fall into the "trap". A well-paying manufacturer will tell you about the concept of "false four-axis", that is, the four-axis model, but it is a triaxial theory. Why does this phenomenon occur? It stems from carving, some small ones like olives. Nuclear-sized samples have a small amount of deformation during the engraving process. This type of bas-relief carving is suitable for pseudo-four-axis and long columns. Some symmetrical or round patterns are suitable for engraving, but for some asymmetrical or square shapes, Rectangular, in the sculpture process deformation is too large, not suitable for pseudo four axis, so those who carved Guanyin or Buddha ornaments do not consider this false four axis.
The true four-axis is four thousand dollars more expensive than the fake four-axis. Fake four-axis carving out the knife on the line, really four-axis use PM knife out.
True four-axis, the general manufacturer's meaning is four-axis three linkage, and all are used PM carving knife to carving, PM this software is cracked, poor domestic software technology, so this software is famous. The most common, but the calculation is slower. Engraving efficiency is not high. However, the Chinese can make multiple carvings at once to compensate for inefficiency. This is a multi-head engraving machine.
