Laser cutting machine precision positioning

by:Transon     2020-10-31
The cutting precision of laser cutting machine is associated with the laser output power of laser generated, there is a more important point is that laser cutting machine precision positioning. About the problem of positioning technology, is how to make subtle positioning technology in the field of spread to the broader field, although reports have proposed using ja can achieve nanometer accuracy of ultra-precision positioning screw, but in most cases, and cannot be accomplished with simple feed mechanism. Especially like a robot, to more than one degree of freedom of position, posture ( Rotation) Many degrees of freedom for the purpose of structure, requirements must be equipped with coarse micro structure. And the micro structure of the multi degree of freedom, in order to precise control the movement of the movement object in any direction, the direction with the same degrees of freedom of movement characteristics, this section is also very important. If you can make good use like with rotator guide, rolling the characteristics of the liquid in the field of small, can achieve sub-micron unit technology. In addition to the report, the use of friction between the roller and slider driving characteristics to achieve nanoscale ultra-precision positioning.
