The ML-Z 9500 Series CO2 laser marker from Keyence can mark not only in the X and Y direction but also in the Z direction. This three-axis motion provides advantages including a 42-mm variable focal length, distortion-free 300 x 300 mm marking area, and the ability to mark clearly on difficult shapes such as cylinders, cones, inclined planes, and spheres. Speeds up to 12,000 mm/s are possible without compromising character clarity. Maximum spot position can be set at any focal length within a 42-mm range. This range of focal length reduces installation time and cost by eliminating the need for a mechanical stage that adjusts during product changeovers or when it is necessary to mark products of varying heights.
