"Dicyclohexylamine: The Magician in cutting Fluids."

Cutting fluid, as an important part of machining, not only plays a lubricating role, but also effectively reduces the heat between the workpiece and the tool, thereby improving processing efficiency and product quality. Dicyclohexylamine, as an organic compound, is widely used in many fields because of its unique surface activity and lubrication properties.

Adding dicyclohexylamine to the cutting fluid can play the following key roles:

1. Reduce the adhesive cutting phenomenon of aluminum alloy cutting: Aluminum alloy due to its special adhesive cutting properties, in the cutting process is prone to surface defects such as clamping, squeezing and burr. The addition of dicyclohexylamine can effectively reduce the adhesion between aluminum alloy and the tool, so as to significantly reduce the adhesion phenomenon and improve the processing quality.

2. Improve processing accuracy: methylene and imine in dicyclohexylamine molecules are electron rich, making it easy to form a protective film on the metal surface. This layer of protective film can not only reduce the heat wear and corrosion during the cutting process, but also improve the processing accuracy. At the same time, it can also effectively reduce the accumulation of products such as hydrogen in the cutting fluid, so as to avoid safety hazards.

3. Extend tool life: The protective film formed by dicyclohexylamine and iron surface can significantly reduce the wear and corrosion of the tool surface, thereby extending the service life of the tool. In addition, because dicyclohexylamine also has excellent anti-rust properties, it can provide additional protection for the tool.

Suitability and safety of cyclohexylamine as cutting fluid additive

Although dicyclohexylamine has many excellent properties in cutting fluid, in practical applications, the addition amount and operating conditions need to be specifically determined according to different processing materials, cutting fluid types and operating requirements. At the same time, pay attention to the following safety issues:

Dicyclohexamine is a local anesthetic with certain toxicity. During use, direct contact with the skin and inhalation of gas should be avoided, and protection should be worn if necessary.

When processing high-temperature materials, higher temperatures will degrade dicyclohexylamine molecules, thus affecting the performance of the cutting fluid. Therefore, it is necessary to control parameters such as the temperature and pH value of the cutting fluid to ensure the quality and stability of the cutting fluid.

In the process of using dicyclohexylamine, because dicyclohexylamine molecules are easy to form smoke-like substances, it may affect the health of workers. In order to ensure the safety of use, it is necessary to use an efficient exhaust system for ventilation and ventilation to avoid dicyclohexamine entering the respiratory system and causing harm to the human body.
