In recent years, CNC machining centers have continuously evolved through innovation, resulting in the development of three-axis, four-axis, and five-axis machining centers, as well as turning-milling composite CNC machining centers. Today, we will discuss the distinct characteristics of three-axis, four-axis, and five-axis CNC machining centers.
Three-Axis CNC Machining:
This typically involves three axes of movement in different directions, such as left-right, up-down, and front-back. Three-axis machining can handle one surface at a time, making it suitable for processing disc-like components.
Four-Axis CNC Machining:
In addition to the three linear axes, a rotational axis is added, which usually allows the base plane to rotate 360 degrees. However, it cannot operate at high speeds. This type of machining is more suitable for processing box-like components.
Five-Axis CNC Machining:
This includes an additional rotational axis beyond the four-axis setup, typically allowing the vertical plane to rotate 360 degrees. Five-axis machining centers enable comprehensive machining, allowing for single-clamp processing, which reduces clamping costs and minimizes the risk of scratching the product. They are especially suitable for processing components with multiple positions and surfaces, high precision requirements, and particularly strict shape accuracy.
Although five-axis machining centers have a significant competitive advantage over four-axis and three-axis centers, not all products are suitable for five-axis machining. Products suitable for three-axis machining may not be suitable for five-axis machining. Using a five-axis machining center for products that can be processed with a three-axis center can increase production costs and may not necessarily improve the outcome.
