In milling Inconel 718, Shokrani et al. reports that cryogenic LN2 cooling reduced the tool life compared to dry cutting. Similar results were obtained by Musfirah et al. [35], concluding that the extreme liquid nitrogen low temperature can lead brittleness of tool material and to reduction of Inconel 718 thermal conductivity.
To address this gap, this article provides an investigation on the viability of cryogenic cooling in CNC end-milling of aerospace-grade Ti-6Al-4V alloy using liquid nitrogen in comparison with traditional machining environments.

Reducing the particle size of drug materials down to submicron is an important matter in pharmaceutical industry. Cryogenic milling technology is one of the mechanical milling processes, which is mostly utilized in refining grain size of metal and ceramics at extremely low temperature environment. This technique has not been readily studied in application to medical and biotechnology.
Cryogenic machining firstly has been considered as an eco-friendly and pollution-free machining technology of difficult-to-machine materials, in order to significantly increase the tool life and reduce tool wear due to the reduction of tool-tip temperature [9,10].With further studies of this process, the improved surface integrity has been found in the machined surface of Inconel 718, AISI ...
The CryoMill is a cryogenic grinder designed with user safety in mind. The liquid nitrogen flows through the closed system and the user never comes into direct contact with LN 2 which ensures a high degree of operational safety. The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly cooled.
The geometrical and electronic properties of B-doped ZnO monolayer with the concentrations of 12.5% and 25% have been calculated using the first-principles method. B-doped ZnO monolayer leads to the structural distortion around the doped atoms compared with the pure ZnO sheet. The B-B pair or two B-B pairs doped ZnO monolayer present nonmagnetic metal.
The CNTs/Al2009 composite powders were prepared by cryogenic milling. The CNTs were uniformly dispersed on the surface of Al2009 powders. And then the CNTs/2009Al composites were fabricated by hot extrusion/hot isostatic pressing method. The effects of CNTs content and cryogenic milling process on the dispersion of CNTs in Al2009 matrix, the microstructure of powders and the properties of ...
The influence of cryogenic mechanical milling on the structure and the thermal behavior of isotactic polypropylene was investigated by means of wide-angle X-ray scattering, differential scanning calorimetry and transmission electron microscopy.
