Optical precision translation table is a kind of displacement table in optical adjusting frame, which is mainly used for positioning of mechanical equipment and fixture. It mainly works by moving different directions to the designated position. We have one-dimensional, two-dimensional, three-dimensional and so on multi-dimensional movement in different directions.

 

 

 

When choosing the precise translation platform, we should first determine whether it needs manual adjustment or motor control, and then determine the displacement stroke, load size, displacement accuracy, resolution, desired shape size, or whether quantitative.

 

Electric translation table controlled by motor can subdivide the circuit, achieve ultra-micro-meter resolution, and achieve automation through computer control. Electric translation table mostly uses ball screw drive, circular linear bearings or linear sliders as guideways, so the travel can be large, up to 1 meter, load can reach 50kg (slow speed can also be improved), accuracy can also be achieved. It reaches micron level, but the price is on the high side.

 

The characteristics of precision translation table:

 

 

 

1. The guide rail is a linear ball grinding steel rod with light load.

 

2. Precision machined base and table surface to make the running straightness, yaw, pitch and motion parallelism of the table within a certain precision range

 

3. Displacement adjustment is driven by fine-tuned thread pair

 

4. Micro-adjustment to ensure micro-feed on the table

 

5. The fine-tuning thread pair is placed in the center of the translation table, which is easy to operate.
