Features of Manual Positioning Stages

(1) High-quality material: The whole stage is made of stainless steel or aluminum alloy, which has better rigidity and stability. After replacing the special vacuum grease, it can be used in a vacuum environment and is suitable for optical experiments and other fields that require high manual adjustment accuracy.

(2) Linear ball guides, crossed roller guides, dovetail guides and steel ball guides are used, and different guides can be selected according to different needs of customers. The Cross Roller Guide increases the effective contact length of the rollers by adopting a unique roller retaining mechanism called the R-type roller cage that shortens the distance between the rollers. The rated overturning moment is large, the rolling elements are arranged in a cross, and the force is applied in multiple directions. Its high-precision surface has undergone special heat treatment, and it is a high-rigidity, rigid-precision, compact finite linear motion system. The effective stroke of the linear ball guide is higher than that of the cross roller guide when the length is the same. Steel ball guides and dovetail guides are cheaper.

(3) There are many kinds of driving mechanisms for the manual positioning stage. For translation stage or lifting stage, there are differential head, thread pair, grinding screw, gear set, rack and pinion, cam type, wedge type and other mechanisms; For the rotary table and the goniometric stage, worm gear transmission mechanism is widely used.

(4) Precise adjustment: It adopts ultra-fine tooth fine-grinding thread pair, and the thread pair has a unique locking mechanism, which effectively improves the stability and sensitivity.

(5) Double locking mechanism: The rear end of the threaded pair has an inner hexagon adjustment hole, which can be adjusted with the standard adjustment handwheel or with a hexagonal wrench to further enlarge the rotation radius and increase the adjustment sensitivity.

(6) Single-axis or multi-axis (such as X-axis, XY-axis, XYZR-axis) can be selected to meet the needs of users.
