5-Axis CNC Machining
Simultaneous 5-axis machining for complex geometries in a single setup. Reduce lead times, eliminate multiple fixtures, and achieve superior surface quality on parts that would require multiple operations on conventional 3-axis machines.
-
Reduces setups and improves accuracy by machining complex parts in one clamping
-
Reaches undercuts, steep walls, and deep cavities with shorter, more rigid cutting tools
-
Minimizes manual handling and fixture costs while maintaining tight tolerances
-
Shortens lead time from prototype to production for high-complexity components
5-Axis CNC Machining Services
Our 5-axis CNC machining centers handle complex parts from prototype to production. By adding rotational axes to traditional X/Y/Z movement, we machine multiple faces in one setup — eliminating alignment errors and reducing lead time for aerospace, medical, and automotive components.
Advantages of 5-Axis Machining
Eliminates Multiple Setups
Completes five faces in one clamping, saving hours of manual repositioning and eliminating alignment errors between operations
Accesses Deep Cavities
Tilts tool or part to reach undercuts and steep walls that would require long, flexible tools on 3-axis machines
Better Surface Quality
Uses shorter, more rigid tools at optimal angles, reducing vibration and leaving smoother finishes on complex contours
Cuts Fixture Costs
Requires simpler workholding since the part can be repositioned by machine rotation instead of custom fixtures
5-Axis General Tolerances
For most 5-axis machined parts, standard general tolerances follow DIN ISO 2768-m (medium) unless otherwise specified in the drawing. Actual achievable tolerances depend on part geometry, material type, and fixturing method.
| Item | Tolerance | Note |
| Linear dimensions | ±0.01mm ~ ±0.1mm | ±0.01mm achievable on critical features, verified by CMM |
| Hole diameter | ±0.01mm ~ ±0.05mm | Precision bored or reamed holes |
| Hole & feature location | ±0.02mm ~ ±0.05mm | Maintained across multiple faces in one setup |
| Angular tolerance | ±0.5° ~ ±1° | For tilted features and freeform surfaces |
| Surface finish (Ra) | 0.8μm ~ 3.2μm | As-machined, achievable with proper toolpath and tool selection |
| Standard | DIN ISO 2768-m (medium) | Unless otherwise specified in the drawing |
Maximum part size depends on machine configuration and part geometry. Please inquire about parts exceeding standard capacities. Tolerances listed are minimums for ideal conditions. Looser tolerances may apply depending on part geometry, material selection, and specific processing requirements. contact us
