Stages with Step-Motors
This system includes vision CCD cameras, and was used for precision placing of large package, fine lead surface-mount components.
However we supply this product, manufactured in Asia, on an
OEM basis. US suppliers of this type of stage are Xynetics and
Normag. Repeatability is, theoretically speaking, as good as 1
micron. Please specify your reuirements when you enquire.

1 Axis Stage, Motor, Microstepping Drive = $1149
Call if you want this stage mounted on a granite surface plate, or if you need a small high speed air bearing spindle on the same surface plate. This can be the basis of a diamond turning lathe, if you wish. Utilize Parker/Compumotor model 6200 indexer, or Ability Systems' software on a PC for the controller.
