It is understood that the tool cold treatment process refers to the martensitic transformation of the termination point will drop below 0 ℃ low temperature, quenched after the organization contains a large number of retained austenite, in order to convert the retained austenite into martensite, After quenching the workpiece into the cold agent or chiller to continue the practice of cooling.

The cold treatment process has its own presence in the value of the machine that has been processed by ice-cold processing, and there are other machines that can not be compared to yours. Such as the air turbine refrigerator is based on the basic principles of compressed air expansion refrigeration manufacturing, its characteristics are significant, first, the cooling speed, can quickly reach the process temperature. Second, the environment pollution-free, cooling medium for compressed air. Third, the working temperature range is wide and frost free. Fourth, the freezer, low temperature box separation, easy to upgrade. The most important thing is that it is simple to operate, easy maintenance.

    

    Tool cold treatment process is based on the chemical composition of steel for scientific manufacturing, these technologies applied to the tool, measuring tools, precision instruments, not only improve the value of the use of the product, but also greatly improve the efficiency.
