Precision Laser Cutting Machine

BackgroundThe customer is an OEM with a small-power laser cutting machine that employs laser technology for precision cutting various metals. Used primarily in the machine tool industry, the device relies on efficiency and accuracy to deliver high quality products that meet the high standards required by modern manufacturers for precision machining.


The Challenge

Because laser cutting machines require high levels of accuracy, the customer was looking for a high value motion control solution that enhanced performance, reduced error rates and delivered high precision.


The Benefits

The chosen solution from FLEXEMATiC delivers enhanced equipment performance through more precise servo control, alongside cost advantages compared with competitors’ solutions. FLEXEMATiC solution delivers absolute positioning accuracy of ≤ 2 microns, repeatability of ≤ ±0.5 microns and operating speed of 1m/s in both X and Y directions.


FLEXEMATiC was able to provide a follow-up error rate of ≤5 µm. The Parkson system’s command cutting trajectory has a minimum diameter circle of 0.2 mm, with errors within one thread throughout the process. The instantaneous speed of the lifting Z-axis can reach 5000 rpm.


The Solution

The solution utilizes an industrial computer with motion control cards. A FLEXEMATiC FV5-U3-NA3R0 servo drive with a 400W output power is employed for the XY axis, paired with a DDL motor. For the Z axis, FV5-U3-NA1R6 drive is used to power a rotary motor with a lead screw.
