The Maintenance of Vision Measuring Machine

The daily maintenance of vision measuring machine is very important. Here are some common faults and some basic maintenance methods. Hope to be helpful to instrument users.

1. Accuracy

In the use of measuring instruments, the biggest problem is that the accuracy is not accurate, resulting in a large error. For example, the accuracy of the x, y, and z axes is inaccurate. First of all, x, y, z drives and x, y grating ruler are basically adjusted when they leave the factory, so do not unpack the machine as soon as you buy it. To avoid impact during use, care should be taken when moving the machine. The fixing block of the workbench must be installed first to prevent collisions resulting in large accuracy errors.

Secondly, the instrument should be placed in a dry, clean, vibrating environment. And ensure that there is a room with a constant temperature, and cover it with a dust cover when not in use. Otherwise, it will lead to rust of instrument components and affect the accuracy of optical components.

2. Projection

Faults of the projection screen include sound, rotational friction, non-uniformity, and not counting when the projector is rotating. These can be solved by replacing parts and adjusting parts. Can not use the hand to touch the projection screen, if there are oil stains, can only use skim gauze to touch the cleanser a small amount of wipe, and then wipe with a small amount of water. Be sure to wipe gently.

Projection imaging faults include image blur, dark contrast and dark area; There are black spots in the image. In order to solve these problems, we can replace the filament, clean the mirror, mirror, table glass, etc. Install a voltage regulator to adjust the voltage to stabilize the bulb. Also note that the cleaning solution should be soft and have a 1:4 ratio of alcohol to ether. You can also use a soft cleaner, such as a brush, to remove dust from the surface.

3. Others

There are also imaging failures, electrical failures, workbench failures, etc., which may need to be repaired by adjusting or replacing parts. But there is no special maintenance method. In short, this kind of precision instrument must be well maintained and maintained. If there is a problem, you must ask the manufacturer to repair it. Therefore, the purchase of measuring instruments is also best to buy from the manufacturer, so that the after-sales aspect can be better protected.
