Simultaneous vs. Indexed 5-Axis
We employ both strategies based on your part requirements:
- Simultaneous 5-Axis Machining: All five axes move continuously during cutting, ideal for complex sculpted surfaces, impellers, blisks, and aerospace contours .
- Indexed 5-Axis Machining (3+2): The part is rotated to optimal positions, then machined with 3-axis moves - perfect for complex prismatic parts with features on multiple faces .
The Challenge of Large-Format Precision
Machining large components presents unique challenges that our experienced team is equipped to handle :
- Thermal stability across massive workpieces
- Tool deflection management for deep reaches
- Chip evacuation from deep cavities
- Workholding for non-rigid or heavy parts
- In-process verification of critical features
Our End-to-End Large 5-Axis Machining Process

Your 2D/3D drawings (STEP, IGES, DXF, DWG, PDF) are reviewed by our senior programmers.
We analyze material selection, critical tolerances, and optimal machining strategies.
Advanced CAM software simulates the entire machining process, verifying toolpaths and detecting potential collisions before any metal is cut .
