The hot summer is here, and the temperature of the factory floor is also rising. How to maintain precision equipment under high temperatures?
The more sophisticated the equipment, the stricter the requirements for the ambient temperature used, which requires the attention of factory managers.
01
Unstable accuracy
For high-precision machining, the temperature problem must not be ignored, because the temperature difference is the enemy of accuracy.
Most of the machine components are steel and cast iron, which will change shape and length according to the room temperature and the heat generated by the machine itself!
For high-precision machining of less than 3μm, the temperature must be controlled at a constant 20°C, with fluctuations less than 0.5°C/hour, and the air conditioning system maintains a constant temperature difference of ±1°C throughout the day.
02
Malfunction
(1) Avoid machine failure or damage caused by condensation
For machine tools that use working fluid, such as machining centers, slow wire machine tools, and mirror discharge machines, when the ambient temperature is too high, the temperature of the working fluid will be higher, and once the temperature of the working fluid is too high, the machine will strike.
During the processing, the appropriate ambient temperature should be set, and the refrigerator should be used to keep the working fluid consistent with the ambient temperature to avoid equipment failure.
(2) Do a good job in the prevention of numerical control equipment
Do a good job in the prevention of numerical control equipment to ensure the normal operation of numerical control equipment.
1) The air conditioner of the distribution box can work normally.
2) The door of the distribution box is tightly sealed.
3) The power supply, drive circuit board, etc. with cooling fans can operate normally, and the cooling conditions are met.
4) Clean the ventilation trenches and heat sinks on the high-power circuit boards.
5) Maintenance personnel should conduct frequent inspections to eliminate hidden dangers in time.
