Traditional CNC machines move on three linear axes ( X, Y, and Z). Five-axis machines move on all three linear axes and two additional rotary axes. The ability to precisely move a workpiece without removing it has clear advantages over traditional 3-axis machining. The machine tools used for 5-axis machining services are often referred to as 5-axis machine tools or 5-axis machining service centers.
5-axis machining services are often used in the aerospace field to machine airframe parts with free-form surfaces, turbine parts, and impellers. The five-axis machine tool can process different sides of the workpiece without changing the position of the workpiece on the machine tool, which can greatly improve the processing efficiency of prismatic parts.
1. Complex shapes. The main (and best known) advantage of 5-axis machining services is the ability to machine complex shapes. The extra movement creates machining angles and arcs that were previously only possible with a number of special fixtures or extra setups.
2. Fewer settings. The five-axis machine can machine almost all visible surfaces, excluding the bottom or clamping area. 5-Axis Machining Services This broad capability reduces the need for multiple setups or special fixtures.
3. Relationship accuracy. Imprecision finds a way to percolate into every setting change. Once the part comes out of the machine, the precise alignment is lost. Feature-to-feature accuracy can be improved by using the same "zero" or "home" location.
4. 3+2 axis machining. Some parts can only be serviced through 5-axis machining. There are also parts that can be machined more efficiently with 3+2 motion. In 3+2 machining, the fourth and fifth axes are used to position the workpiece (or tool, depending on the type of machine) in a fixed position. In these cases, all five axes do not need to move at the same time. Five-axis machines increase uptime, reduce human error, and eliminate the need for special fixtures. For parts with features or holes on multiple faces or angles, 3+2 machining is the clear choice.
5. Better surface finish. With 5-axis machining services, the part can be positioned to bring it closer to the cutting tool. If the part can be closer to the cutting tool, then the cutting tool can be shorter. Shorter tools are less susceptible to vibration at higher cutting speeds, which directly affects surface finish.
