What is the difference between 3-axis, 4-axis and 5-axis in CNC? What is suitable for machining3/24/2025Parameter Dimension3 Axis CNC4 Axis CNC5 Axis CNCAxis Definition- 3 linear axes: X, Y, Z- The tool moves in a straight line, machining a single plane in a single pass.- 3 linear axes + 1 rotary axis (e.g. A-axis)- Linear and rotary axes are linked to machine multi-angle planes.- 3 linear axes + 2 rotary axes (e.g. A/B or B/C)- 5-axis linkage, tool can cut into workpiece from any angleAccuracy- Low (±0.05mm class)- Multiple clamping error prone- Medium (±0.02mm class)- Reduced number of clamping times improves accuracy- Highest (±0.005mm class, micron class)- Linkage processing avoids interference, resulting in high precisionMachining efficiency- Low- Complex parts require multiple clamping and turning- Medium-high- Multi-face machining in one clamping, 30%-50% increase in efficiency.- Highest- Complete the whole process in one setup, 20%-40% more efficient than 4-axis.Machining types- Surface milling, drilling, simple 2D/2.5D parts- Regular surfaces (e.g. cylindrical surfaces)- Multi-surface machining, cylinder side profile- Moderately complex surfaces (e.g., convex molds for automotive molds)- Complex free-form surfaces (e.g., impellers, propellers)- Inverted features, multi-curvature transition parts¨NBSP; prevWhat exactly is China's advantage in cncnextWhat is the most advanced brand of cnc machining equipment available and how strong is it?
