Technological, economical and ecological aspects of high efficient cooling

The diploma thesis is aimed to the influence of the high-pressure and low-pressure coolant system according to the machining operation. The comparison was carried out with different types of materials and cutting tools using the main machining operations – turning, milling, and drilling. The study is focused on the chip and heat removal from the cutting zone, tools life and wear of the tools. A description of the basic principle of the high-pressure coolant system meant is described in this thesis. The economical analysis of the high-pressure compared to low-pressure system was determined in the last part of this work
