The New KEYENCE MD-X2000/2500 Laser Marker

KEYENCE announces the latest in the MD-X Laser Marker Series. The MD-X2000/2500 3-axis hybrid laser marker. It has a built-in distance sensor that constantly measures the distance to the marking location and focuses on that location, eliminating the need for manual fixturing or alignment. By tracking unintentional deviation in the height or inclination of the target, marking defects can be prevented over the entire marking area. The two built-in cameras in the head allow alignment without the need for external equipment. This prevents marking errors due to positional deviation. Because the laser marker focuses itself, troublesome adjustments and changeovers are not required. Deviation in the target is identified and automatically corrected, enabling stable marking.

Unlike other conventional methods in which the laser pointer is monitored by the built-in camera, the built-in distance sensor’s laser directly illuminates the measurement locations to take measurements. This maintains high marking quality over the entire marking area. In essence, the focal distance to the marking location is measured and corrected before marking.

The peak power of the MD-X Series is 200 kW, twice that of a conventional YVO4 laser. A high-output, short-pulse laser with a minimum pulse duration of 4 ns minimizes thermal damage to the target. It is ideal for applications where users want to minimize the effects of heat, such as contrast marking on resin.

The MD-X Series has a depth of focus that is characteristic of YVO4 laser oscillators. Depth of focus is an important factor for basic performance to achieve and maintain marking quality. When used in combination with the Z tracking function, this also results in high tolerance to height deviation.

No External Equipment Required for Predictive Maintenance or Troubleshooting Various factors must be considered the cause of marking defects, from target position deviation, to lens flaws, to drops in output power. Marking defects that occurred suddenly were difficult to reproduce, and it was often difficult to identify the cause. The MD-X Series offers a wide range of monitoring functions, from predictive maintenance to cause analysis when a marking defect occurs, without the need for external equipment. By using the Web Monitoring function, the status of the marking process can be obtained accurately, even from a remote location.
