Analysis of Cleaning of CNC Machine Cooling Device

The cooling device of the CNC machine tool is just as important as the lubricating device. Good cooling can improve the machining quality of the workpiece and the service life of the machine tool components. Under normal circumstances, the daily maintenance of the cooling device is mainly the replenishment and replacement of the cooling liquid and the cleaning of the filtering device.

Then, when should the cooling device be maintained? 1. Observe the oil mark on the front of the tank. When the cooling water is reduced, it should be added in time. Under normal circumstances, the configuration of the water outlet around the main shaft should at least make the oil filter of the cooling pump inlet completely submerged.

2. When the cooling water is contaminated and deteriorated, it should be replaced in a timely manner. The screw plug below the water tank should be removed to discharge the waste liquid. After cleaning the water tank, a new, clean coolant can be filled.

3. The cooling water tank is divided into two chambers: the water tank and the pump box. It is easy to raise the filter when it needs to be cleaned. The cleaning is very convenient. In addition, an oil filter is installed at the entrance of the cooling pump. The above two devices are used for a certain time in the machine tool. After a timely inspection and cleaning.

4. In general, the oil filter and filter should be cleaned once every two months.

The maintenance of the machinery is different, but there are many common points, so the maintenance of CNC machine tools is also very important.

Calcium Carbide

Calcium carbide is an inorganic substance, the chemical formula is CaC2, the main component of calcium carbide, white crystals, industrial products are gray-black lumps, and the cross section is purple or gray. It reacts violently when encountering water, generating acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding, etc.

Acetylene produced by the reaction of calcium carbide with water can synthesize many organic compounds such as synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc.; at the same time, acetylene-oxygen flame is widely used in metal welding and cutting.

Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. The relative humidity is kept below 75%. The packaging must be sealed and protected from moisture. It should be stored separately from acids and alcohols, and avoid mixed storage. The storage area should be equipped with suitable materials to contain the leakage.
