This year, the H 630 horizontal centre was installed at the Faculty of Mechanical Engineering of the Czech Technical University (CTU) in Prague. The machine was purchased mainly for research of machining process and application of automation technology and robotics. A novelty is integrated in the machine – a single-channel tool cooling unit using liquid CO2.

The H 630 is currently the only machine in the Czech Republic that can offer this unique cryogenic tool cooling technology as serially integrated.

In addition to its superior equipment, the machine can proudly display support of functionalities according to the requirements of Industry 4.0 and a faithful digital twin of the machining process simulation.

This month, in the Industry 4.0 testbed at CIIRC CTU in Prague, the first operational tests of machining with cryogenic tool cooling using liquid CO2 took place. This is a technological innovation in the field of cryogenic cooling, which was developed by the Technical University of Ljubljana. Liquid CO2 mixed with lubricant is supplied via the spindle into the tool through one channel only, where a temperature of -70 °C is reached at the end of the tool due to the expansion of the liquid CO2. By this, the tool temperature during machining is reduced, allowing a significant increase of the cutting parameters and an extension of the tool life.

Cryogenic cooling technology is designed for machining difficult-to-machine materials such as titanium and nickel alloys or heat resistant steels.

The operational test of machining with cryogenic cooling by liquid CO2 was attended by representatives of the technical department and CTU researchers led by Petr Kolar. Prof. Franci Pusavec from TU Ljubljana and Prof. Pedro Arrazola from Mondragon University were distinguished guests in the laboratory.
