XYZR 4 Axis 3.54"x3.54" Manual Linear Positioning Stage Bearing Tuning Platform Sliding Table 90mmx90mm

I would have given five stars to this product because it is well made and solid. Nevertheless, two areas of the vessel were damaged when it arrived. In order to give it a 1 star if I needed to have all four degrees of freedom, I would have had to give it a minus, since the There is a screw with a 2-inch length One-fourth of an inch long was bent away from the screw so that it cannot be screwed further away from where it had been bending. I would probably never use the lock, since the unit rotates well, and the lock works fine otherwise. An operational issue with one of the linear micrometers caused the most concern. In order to hold the micrometer in place, each device is clamped in an aluminum block. As can be seen in the product images, the micrometers extend from the block in a cantilever fashion. A side force can cause damage to them at the outboard end due to their design. An end of the micrometer itself bumped against the side of the unit when the screws holding it in place were partially pulled out of the base plate. This means that the affected micrometer is lying at a horizontal angle relative to the side of the unit rather than In addition, it is also vertically tilted to a significant degree. There's no function to it. As it happens, I am not in need of the particular degree of freedom involved in my application. It arrived packaged in a box within a box. Both the box within the box and the box between the boxes were tightly wrapped with bubble wrap. Although they were supposed to be designed to take the load they were apparently exposed to during shipment, the cantilevered micrometer mounts (and the rotation stop screw) were actually not designed to support those loads. Although the unit is substantial and heavy, the micrometer mounts were not meant for heavy side loads at their exposed ends, though they are not flimsy. Packages endure the greatest weight at their weakest points and are therefore the most vulnerable to shipping loads. In order to prevent this from happening, there are two simple steps you can take I. 1. In order to avoid damage during shipping, pack the unit so the protruding micrometers and screws can't touch anything. Please specify 2. If the micrometers and any long projecting screws are shipped detached and packaged separately, the main unit can be shipped. You should also provide the customer with a diagram showing where the items are to be installed. Having seen the damage by photographs, I can provide documentation.

In terms of performance, the stage performs well. It has no backlash, smooth positional control, good stability, and no shortcomings that I have Comparatively speaking, the price of this stage is very reasonable, compared with other similar products sold by lab supply websites.
