Precision positioning tableWidely used in fields such as optical measurement, semiconductor manufacturing, biological experiments, and automated assembly that require high displacement accuracy. Its core function is to achieve high-precision motion control at the micrometer or even nanometer level. Therefore, scientific inspection and maintenance before and after use are crucial to ensure the stability of equipment operation and extend its service life.

1、 Key points for inspection before use

1. Appearance inspection

Check whether there are scratches, deformations, or rust on the surface of the positioning platform, especially whether key moving parts such as guide rails and sliders are intact. If there are any abnormalities, the use should be suspended and reported for repair.

2. Clean the work platform

Use a dust-free cloth dipped in an appropriate amount of alcohol to gently wipe the surface of the platform, removing dust, oil stains, or other impurities to prevent foreign objects from affecting positioning accuracy or damaging precision structures.

3. Check the drive system

For manual positioning stations, it is necessary to confirm whether the knob rotates smoothly and whether there is any jamming; For electric positioning stations, it is necessary to check whether the motor connection is firm, whether the control cables are intact, and test whether each axis runs smoothly and responds sensitively when powered on.

4. Verify the status of limit switches and sensors

Confirm the reliable operation of the limit switch to avoid damage to the mechanical structure caused by overtravel; The signal feedback of photoelectric or magnetic sensors is normal, ensuring that the control system can accurately identify the position information.

5. Confirmation of environmental conditions

Check whether the laboratory temperature and humidity meet the equipment requirements (usually recommended temperature of 20-25 ℃, humidity<60%), to avoid affecting accuracy and electronic component life due to thermal expansion and contraction or high humidity.

2、 Maintenance measures after use

1. Clean residues in a timely manner

After use, use a soft bristled brush to remove debris from the guide rail and platform, and then gently wipe with a dust-free cloth again to prevent particles from entering the sliding mechanism and causing wear.

2. Lubrication maintenance (if applicable)

partPrecision positioning tableIt is necessary to regularly add specialized lubricating oil or grease to the guide rail or screw. The operation should be carried out according to the recommended cycle in the manual to avoid excessive lubrication or the use of incompatible grease.

3. Power outage protection and dust prevention treatment

Turn off the power switch, unplug the power plug (if it is an external power supply), and install a dust cover on the positioning table to prevent dust from entering the interior and affecting accuracy.

4. Record usage status

It is recommended to establish a device usage log to record each operation parameter, abnormal phenomenon, maintenance record, etc., in order to track the equipment status in the later stage and detect potential problems in advance.

5. Regular calibration and professional testing

It is recommended to have professional technicians conduct comprehensive calibration and performance testing every six months to one year to ensure that the positioning accuracy is always in a good state.

As the core equipment for high-precision motion control, the performance of the precision positioning platform directly affects the stability of the entire system and the reliability of measurement results. Only through careful inspection before use and standardized maintenance after use can the service life of equipment be effectively extended, ensuring efficient and precise operation of scientific research and production work.
