For parts with curved surfaces or arc features, different machining strategies can produce different results.
Traditional Z-level layer cutting often leaves visible step marks on the machined surface, requiring additional polishing.
At Lianyang Metal, we use 4-axis helical machining to improve machining quality.
Constant Cutting Load
The cutting tool moves smoothly along a spiral path with fewer sudden changes in direction.
This helps reduce machine vibration and extends tool life.
Better Surface Finish
Compared with traditional layer cutting, the spiral toolpath greatly reduces step marks on the machined surface.
As a result, less polishing—or in some cases no polishing—is required after machining.
Improved Chip Removal
The upward spiral cutting path allows chips to be removed more effectively, reducing the possibility of damaging the finished surface.
For long shaft components and eccentric parts, 4-axis helical machining also helps achieve higher roundness and cylindricity.
