Why Choose 5-Axis Machining with 6CProto
With numerous precision machining providers to choose from, why should you partner with 6CProto? Here are four key reasons that set us apart:
3+2 Axis Machining Vs Simultaneous
Strictly speaking, 3+2 axis machining also uses five axes, but it differs from true simultaneous 5-axis machining. In 3+2 machining, the cutting tool is positioned using two rotary axes before the three linear axes perform the cutting. In contrast, simultaneous 5-axis machining moves all five axes at once, allowing for faster production and superior surface quality on complex, contoured parts.


Feature
Simultaneous 5-Axis Machining
3+2 Axis Machining
Movement
Simultaneous 5-axis machining continuously moves all axes, allowing the cutting tool to glide smoothly between passes for faster, more efficient production.
In 3+2 axis machining, the cutting tool moves along the X, Y, and Z axes while the fourth and fifth axes adjust to a fixed angle. Although this method can be slower than simultaneous five-axis CNC, it improves part rigidity and extends tool life.
