Laser micro machining machines
Laser micro machining system ABLASER
Company：NIDEC MACHINE TOOL CORPORATION
The original laser head technologies are for high precision and high efficiency.
Features
The optical laser head on the original technologies enables high precision helical machining.
The laser head adopts a prism rotator that adjusts and rotates the laser beam to an arbitrary hole diameter, enabling shape processing with sharp edges. It is also possible to drill holes of any cross-sectional shape, such as straight, tapered, reverse tapered or hand-drum-shaped.
