精密仪器的保养方法如下:
一、日常维护和保养
(1) 开机前的准备
a、影像测量仪对环境要求比较严格，应按要求严格控制环境温度(20℃士2℃)及湿度(30～80%).
b、影像测量仪的导轨精度很高，如果导轨上面有灰尘或其他杂质，就容易造成导轨划伤。金属导轨可用航空汽油擦拭(120或180号汽油)，花岗石导轨用无水乙醇擦拭。
c、在保养过程中不能给任何导轨上任何性质的油脂。
d、定期给光杆，丝杆或磁条等传动部件上少量防锈油。
e、长时间未使用影像测量仪，在开机前应做好准备工作:控制室内的温度和和湿度(24小时以上)，检查电源等部件是否正常。
f、开机前检查电源，如有条件应配置稳压电源，定期检查接地。
(2) 测量过程的准备
a、被测工件在放到工作台上检测之前，应先清洗去毛刺，防止在加工完成后工件表面残留的冷却液及加工残留物影像测量仪的测量精度及使用寿命。
b、被测工件在测量之前应在室内进行恒温，如果温度相差过大会影响测量精度。
c、大型及重型工件在放置到工作台上的过程中应轻放，以避免造成剧烈碰撞，致使工作台或工件损伤。
d、小型及轻型工件放到工作台后，应夹装牢固后再进行测量，否则会影响测量精度。
e、在工作中移动Z轴时，应注意让镜头在移动过程中远离工件，以避免碰撞。
(3) 测量结束后
a、测量结束后要清洁工作台面。
b、检查导轨，防止有杂物，水渍残留
c、工作结束后将机器总电源等关闭。
二、长期维护
1、环境要求
影像测量仪最好能放在清洁，于净的场所，对环境的要求主要有:
a、光照：影像测量仪不能放置强光或太阳直射的光照环境下，否则将会极大影响测量精度。
b、油污: 影像测量仪是精密仪器,其光栅尺，导轨，平台玻璃和镜头都不能沾染油污，否则会影响测量的精度和仪器的操作性能.
c、避振:如果影像测量仪受到额外的环境振动，测盘的精度将会变低．当频率小于10Hz ，周围振动的振幅不应该超过2um(峰~峰差值);当颊率在10Hz到 50Hz之.间，则加速度不应该超过.0.4Gal.如果振动超过这些限制,应该采用防振措施（如安装振动阻尼器)
d、无尘:影响测盘仪各部件必须保证无灰尘。需定期清洁。
e、温度:环境温度保持在20℃士1℃。时的精度。
f、湿度:湿度对测量精度没有不利的影响,不过高湿度会使重要的-机械表面生锈，阻碍平滑的轴向移动。困此建议环境湿度保持在30℃至m80℃之间.
g、电源:220V50Hz 10A
(2) 部件维护要求
a、测量平台:在装卸工件时要特别小心玻璃平台。测量平台上不可放置过重的测量工件。当测量平台附着水气及油雾层时,请使用清洁剂清除污垢.
b、机身外壳:一机身外壳遭近染时,用软布擦拭干净。机身外壳的的污染并不会影响测量精度，但污染可能扩散至线性滑轨或平台等对测量精度有影响的机身其他部分
c、玻璃类组件,玻璃工件应保持清洁,不可沾上污垢,否则可能导致成像不清晰,测量精度下降。
镜头:不可用手触碰镜头。如果镜头表面有手纹或油污,可用长:纤维脱脂棉球或专用的镜头纸，蘸专用的镜头清洁剂擦拭,也可用纱布浸湿酒精轻轻擦拭。如果灰尘较多，则用吹气球吹掉,或专用的气体清洁剂，镜头毛刷,不可嘴吹。
测量平台玻璃:放置测量工件时容易划伤玻璃面,需要特别注意若沾上油垢或灰尘用软布擦拭。
Image measuring instrument as a precision measuring instrument, if the maintenance and maintenance is not timely, it can shorten the service life of the machine, on the contrary, it can not only prolong the service life, but also ensure the accuracy, reduce the failure rate.
The maintenance methods of precision instruments are as follows:
One, daily maintenance and maintenance
(1) Preparation before starting up
A. The image measuring instrument has strict environmental requirements, and the ambient temperature (20℃ 2℃) and humidity (30 ~ 80%) should be strictly controlled according to the requirements.
B. The guide rail of the image measuring instrument has high precision. If there is dust or other impurities on the guide rail, it is easy to cause the guide rail scratch. Metallic guide rail can be wiped with aviation gasoline (120 or 180 gasoline), granite guide with anhydrous ethanol wipe.
C, in the maintenance process, can not give any grease of any nature on the guide rail.
D, regularly give light rod, screw rod or magnetic strip and other transmission parts on a small amount of anti-rust oil.
E. If the image measuring instrument has not been used for a long time, preparations should be made before starting the instrument: control the temperature and humidity of the room (more than 24 hours), check whether the power supply and other parts are normal.
F. Check the power supply before starting the machine. If possible, it should be equipped with a regulated power supply and check the grounding regularly.
(2) Preparation of the measurement process
A. Before the workpiece is placed on the workbench for testing, it should be cleaned and deburred to prevent the coolant remaining on the workpiece surface after processing and the measuring accuracy and service life of the image measuring instrument for processing residue.
B. The workpiece to be measured should be kept at a constant temperature in the room before measurement. If the temperature difference is too large, the measurement accuracy will be affected.
C. Large and heavy workpieces should be placed gently in the process of the worktable, in order to avoid violent collision, resulting in damage to the worktable or workpiece.
D. After small and light workpiece is placed on the workbench, it should be clamped firmly before measurement, otherwise the measurement accuracy will be affected.
E. When moving the Z-axis at work, pay attention to keeping the lens away from the workpiece in the process of moving to avoid collision.
(3) After the measurement
A, after the measurement to clean the work table.
B. Check the guide rail to prevent sundries and residual water stains
C. Turn off the main power supply of the machine after work.
Two, long-term maintenance
1. Environmental requirements
It is best to put the image measuring instrument in a clean and clean place. The main requirements for the environment are:
A. Illumination: The image measuring instrument should not be placed under the illumination environment of strong light or direct sunlight, otherwise the measurement accuracy will be greatly affected.
B, oil: the image measuring instrument is a precision instrument, its grating ruler, guide rail, platform glass and lens can not be contaminated with oil, otherwise it will affect the measurement accuracy and the operating performance of the instrument.
C, vibration avoidance: if the image measuring instrument is subjected to additional environmental vibration, the accuracy of the measuring panel will be reduced. When the frequency is less than 10Hz, the amplitude of the surrounding vibration should not exceed 2um(peak to peak difference); When the buccal rate is between 10Hz and 50Hz. If the vibration exceeds these limits, anti-vibration measures (e.g., installation of vibration dampers) should be used.
D. Dust-free: all parts of the measuring panel must be dust-free. Clean regularly.
E. Temperature: the ambient temperature shall be kept at 20℃ and 1℃. The accuracy of time.
F, humidity: humidity has no adverse effect on the measurement accuracy, but high humidity will make the important - mechanical surface rust, hinder smooth axial movement. It is recommended that the ambient humidity be kept between 30℃ and M80 ℃.
G, power supply :220V50Hz 10A
(2) Component maintenance requirements
A. Measuring platform: pay special attention to glass platform when loading and unloading work parts. Heavy measuring workpiece shall not be placed on the measuring platform. When the measuring platform is attached to water vapor and oil mist, please use detergent to remove dirt.
B. Fuselage shell: If the fuselage shell is nearly dyed, wipe it clean with a soft cloth. Contamination of the fuselage shell does not affect the measurement accuracy, but contamination may spread to other parts of the fuselage, such as linear rails or platforms, which can affect the measurement accuracy
C. Glass components and glass workpieces should be kept clean and not stained with dirt, otherwise it may lead to unclear imaging and decreased measurement accuracy.
Lens: Do not touch the lens with your hands. If the lens surface has hand lines or oil stains, you can use long: fiber absorbent cotton ball or special lens paper, dip in special lens cleaner to wipe, can also use gauze soaked alcohol gently wipe. If the dust is more, blow off with balloon, or special gas cleaner, lens brush, not mouth blowing.
Measuring platform glass: it is easy to scratch the glass surface when placing the measuring workpiece, so wipe it with a soft cloth if it is stained with oil or dust.
