The precision of laser cut comprises by many sided element:
1, the volume that stimulates the facula after beam of light passes focusing
The facula after stimulating beam of light to gather is smaller, cut precision is taller, cut especially seam lesser, the smallest facula can amount to 0.01mm.
2, the walks along a precision to deciding cut repetition of workbench precision
Workbench precision is taller, the precision of cut is taller.
3, workpiece ply is bigger, precision is lower, cut seam bigger.
Because laser light beam is taper, cut seaming also is cone-shaped, the stainless steel of ply 0.3MM compares 2MM cut seam many small.
4, workpiece material has certain effect to laser cut precision character.
Below similar case, the cut precision that stainless steel wants to compare aluminium is tall, tangent plane is a few smoother.

The cut quality of laser beam cutting machine is good. Cut width is narrow (it is commonly 0.1- - 0.5mm) , precision is tall (general aperture center is apart from an error 0.1- - 0.4mm, outline on size error 0.1- - 0.5mm) , cut surface surface roughness is good (general Ra is 12.5- - 25 μ M) , cut seam do not need rework to be able to solder commonly.
