Three dimensional accuracy calibrationThe precision of large-scale measuring machines composed of components can be affected by factors such as environment (temperature, humidity, dust, etc.) and vibration. Guide operators of 3D to correctly use, maintain, and upkeep 3D precision calibration

1、 Environment

1. Temperature: In order to effectively apply the three-dimensional accuracy calibration performance and ensure its precision, the ambient temperature must be provided at 18 ℃ -22 ℃; If the temperature does not meet the standard, indoor air conditioning is commonly used to increase and decrease the temperature.

2. Humidity: The driving and guiding part of the three-dimensional precision calibration uses air bearings. If the humidity is too high, dust can easily adhere to the air bearings, affecting the movement of the measuring machine. If the humidity is too high, it can also cause important mechanical processing surfaces of the measuring machine to rust. In addition, it can also affect computer electronic components, which can seriously cause chip short circuits and burn out. Therefore, the humidity should be maintained at around 50-60%; If the moderate level does not meet the standard, air conditioning can be used for dehumidification.

3. Other:

A strong electric or magnetic field: can cause damage or interference to the disk program, and the grounding voltage should be less than 5 volts;

Dust: It can adhere to the surface and damage the accuracy or disk of the measuring machine;

Vertical exposure to sunlight or direct blowing from air conditioning equipment: The measuring machine may produce local temperature changes, which can degrade accuracy, and the disk and computer may condense due to temperature differences.

2、 The accuracy and service life of 3D precision calibration depend on daily maintenance, and the maintenance items are as follows:

1. Supply air pressure: Before starting up, check if the three-dimensional precision calibration intake pressure gauge is within the range (0.5kg/cm);

2. Three point vertical filter: Confirm the oil and water content in the air. If there is accumulated oil or water in the glass cup, press the discharge hole below the filter to discharge it. Otherwise, it may cause bearing blockage, affect accuracy, and seriously make the machine unable to operate. When the filter core accumulates oil, it needs to be replaced with a new one;

3. Marble platform: The measuring platform should avoid moisture and oil stains. If there is dirt, it should be wiped with dust-free paper or acetone;

4. X, Y, and Z-axis guide surfaces: When there is moisture, it can affect the operation of three-dimensional accuracy calibration (which may cause rusting or blockage of air bearings). Therefore, before use daily, wipe with dust-free paper dipped in alcohol or acetone. When wiping the Z-axis ceramic guide rail, be careful not to touch the grating ruler to prevent it from falling off;

5. Standard ball: The standard ball is made of ceramic components and should be wiped with dust-free paper before use
