The introduction of Cryonetic machining

Cryonetic machining is a mechanical working process employing the special properties of materials in low/ultra-low temperature condition.

In the low-temperature machining, the use of ultra-low-temperature liquid fluid in the machining system, cutting the area to form local low-temperature (or ultra-low temperature), in order to take advantage of this state object processing and processing tools to change the mechanical properties, so that it is conducive to machining. It can form a better state of processing,especially for some of materials that hard to process，such as titanium alloys, low-alloy steel, low carbon mild steel and particularly some of the toughness of plastic composite materials.

The basic steps of cryonetic machining：

① According to the processing and object processing tool set features the best low-temperature processing temperature Topt;

② the use of low-temperature fluid so that the specific area of closed-end processing temperature Topt;

③ automatic injection of the cryogenic fluid in order to maintain the temperature of processing zones in the state of Topt: On the one hand, when detected in the processing zone temperature deviation Topt, through feedback controller to regulate the flow jet, on the other hand, when the input power processing system Changes directly through the feed-forward regulation of jet traffic controllers in advance in order to maintain the best state of low-temperature processing.
