A tool to reduce cycle time and cost of new technology

Developers say the process by icefly processes. In view of their hair while maintaining a low tolerance, but also can improve the surface quality.

A new hard drive processing forthcoming, its developers say it can be rough grinding time from 4 hours to 15 minutes. In addition, the process is also thought to be reduced to 85% tool costs, while improving the work tolerances and surface roughness.

The process is by Hardinge and Air Products and Chemicals Limited (air products and chemicals inc.) Co-developed, the principle is the turning operation to import liquid nitrogen at the incision site. In this process, liquid nitrogen cooled cutting tool can to a very low temperature, and prevent the formation of temperature rise in the workpiece, and raise the efficiency of the cutting operation, a huge benefit.

This process is called "icefly", according to the technical director ranajit ghosh Air Products icefly production, said the process can be used to replace the coarse grinding operation, the hardness of the material in the roughing operation 78rc tolerances can be maintained at 0.008 inches, while increasing the depth of cut and spindle speed.

ghosh in the second interview that Air Products has developed about five years ago, the application of liquid nitrogen in the process of cutting operations. Using liquid nitrogen in cutting originally developed for the manufacture of flat steel and heavy craft roll support rollers. These rollers are hardened by hard work of its steel manufacturing. ghosh cooling process, said his company is currently in use on five sets of production of this roller machine the United States.
