Much like the milling machine, the 3-axis machining center, we can say that, is a milling machine plus. A milling machine has 2.5 axes, which somewhat limits its machining speed due to the Z-axis not working simultaneously with the X and Y axes. In the machining center, the axes can work simultaneously.
That is, the Z-axis can enter vertically while the table is moving. The ease of using 3 axes simultaneously gives us the freedom to work in a more dynamic and optimized way, reducing machining time considerably compared to a milling machine. Therefore, it is indicated for machining parts of medium complexity that require a large roughing—ideal for tooling manufacturing (molds, dies, fixtures, maintenance parts).
CNC 4 Axis Machining Center
The machining center has the 3 axes of a normal machining center (X, Y, and Z) and a rotational axis. We can say that a 4-axis machining center is a fusion between a machining center and a CNC machine (เครื่อง cnc which is the term in Thai). After all, the fourth axis can be used to turn the part and position it for milling.
Thus, the 4-axis machining center is recommended for parts with high complexity, requiring a lot of finishing, and highly recommended for machining helical parts.
Because, with the fourth axis rotation function, it is possible to machine this type of part optimally.
5 Axis CNC Machining Center
The 5-axis machining center is very similar to the previous one. It also has a rotational axis that can act as a lathe. But unlike 4 axes, this one has a second rotational axis. Generally, one rotational axis controls the part, and the second rotates the tool holder or table. So, a 5-axis machining center is recommended for parts with very high detail complexity. Widely used for manufacturing propellers of all sizes and complexities and also in the machining of turbine rotors.

Electrical Discharge Machining (Electrical Discharge Machining)
In wire machining, an electrode, the thickness of a smaller needle, is used, which machines along a path previously determined by the programmer. The wire cutting method can be used to cut any electrically conductive material. It is an advantageous strategy to reduce costs and also to reduce burrs.
Therefore, it is recommended to machine parts with a degree of fragility. Widely used to machine molds and dies at a lower cost.
