With laser polishing, the risk doesn\u2019t exist and the roughness gain is impressive (up to factor 10).<\/li>\n
- Mechanical polishing of hard material is extremely long. Laser polishing is not sensible to the hardness of metal material and time saving is very important. Here too, the roughness gain factor can be up to 10.<\/li>\n<\/ul>\n<\/div><\/div><\/div>[\/vc_column][vc_column width=”1\/12″][\/vc_column][vc_column width=”6\/12″][vc_row_inner gap=”35″ el_class=”cdev_circle_grid”][vc_column_inner width=”1\/2″ css_animation=”left-to-right” css=”.vc_custom_1580124508980{padding-top: 60px !important;}”]
