The hydraulic oil of the cutting machine is indispensable to the cutting machine. Without the hydraulic oil, the cutting machine cannot run. If the hydraulic oil with poor quality or chemical composition is used, it will cause very serious damage to the hydraulic parts and seals of the cutting machine, have a great impact in the production process, and even lead to the decay of the oil cylinder seal ring, then the stamping head of the cutting machine will automatically decline, and the potential safety hazard is very great.

If the hydraulic oil of the cutting machine is tested without the above conditions, please refer to the following points:

Visual inspection: the hydraulic oil is milky white and turbid, indicating that the hydraulic oil contains a lot of water.

Combustion: touch the hydraulic oil in the oil tank of the cutting machine with a clean sponge and light it. If there is a crackling explosion or flicker, it indicates that there is more moisture in the hydraulic oil.

Smell: take out a small amount of hydraulic oil from the oil tank of the cutting machine and filter it with paper. If there is black residue and pungent smell on the paper, it indicates that the hydraulic oil has deteriorated or contains chemical components.

Note: in order to better use the cutting machine, it is recommended to buy regular hydraulic oil. Don't be greedy for cheap. Exceptionally, the new cutting machine will be used for 6 months, and it is recommended to replace the hydraulic oil within one year at most, because impurities will be generated during the running in period of the cutting machine. Replacing the hydraulic oil at one time is very good for the future use of the cutting machine, and will increase the service cycle of the cutting machine and hydraulic oil.

Selecting a good cutting machine hydraulic oil can increase the oil change cycle of the cutting machine and reduce the maintenance cost of the cutting machine. The quality of hydraulic oil can be distinguished from the professional point of view from the aspects of oxidation resistance, foam resistance, abrasion resistance, smell and color. For example, the following methods to identify the quality of hydraulic oil are:

1. Oxidation resistance: take out a small amount of hydraulic oil and put it into a plastic bottle and expose it to the sun for a period of time. If the color darkens seriously, the hydraulic oil is poor.

2, anti foam: two kinds of hydraulic oil are put into two plastic bottles respectively, shaking violently for a period of time. After static, observe the speed of bubble disappearance, bubble disappear quickly, indicating that hydraulic oil is good.
