Encoder Disks

Encoder DisksChemical etching can be used to make your most challenging encoder disks. Slots can be as small as 1.2 times the thickness of the material. Therefore on .005 thick material the openings can be as small as .006. Etching can also create webs that are as small as 60% of the material thickness. On a .005 thick encoder disk the webs can be as small as .004 wide.

Because our etching process dissolves the extra material it does not add any extra stress to the metal. This will allow the disks to stay as flat as the material with which we started. Chemical etching does not create any burrs on parts thus leaving no extra obstruction on the part.
