Laser micro machining machines
Laser micro machining system ABLASER
Company：NIDEC MACHINE TOOL CORPORATION
Features 1
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.
