Modern cooling lubricant for metal machining
Nováček, Pavel ; Sámelová, Vendula (referee) ; Zemčík, Oskar (advisor)
This work covers the characteristics of different types of processing fluids used in machining; their types, the possible ways to supply and certain operational activities associated with the use of these liquids. The following are some of the modern trends in machining including dry machining, comparing their abilities with the machining process with fluids.

Technological and economic analysis of the production for the automotive industry
Sedláková, Eva ; Petrenec, Martin (referee) ; Píška, Miroslav (advisor)
The thesis deals with an analysis of an existing technology of thread forming under various technological parameters used in car industry. Furthermore, it characterizes metric threads, their production and quality control, forming taps, process fluids and other process parameters. In the experimental part the experimental tests with a conventional and CNC drilling machines were carried out. The influence of various process fluids on surface and thread quality have been assessed statistically. The technical-economic evaluation of the process fluids and their effect on the technology has been made. The work supports a beneficial role of soap and polymers as convenient tribological means at thread forming.

The influence of process fluid on the machining cycle
Ertl, Roman ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
The bachelor’s thesis focuses on literature search of problems of process fluids in the machining cycle. The aim of the thesis is to describe the properties of metalworking fluids and their distribution. Subsequently, the requirements for metalworking fluids from different angles of view are described. Process infuences are also discussed in detail on aspects such as temperature, wear, tool durability, etc. Another aim of the thesis is the feeding of process fluid into the machine’s working space and alternatives to process fluids, where MQL and dry machining are included. Great emphasis is placed on protecting the environment and the influence of liquids on the health of the machine operator. Subsequently, the basic maintenance of metalworking fluid sis described, starting with the creation of a new concentrate until their disposal.

The influence of process liquids on the machining process
Lišková, Tereza ; Strejček, Jan (referee) ; Kalivoda, Milan (advisor)
The content of my study is related to the coolant comparison in machining manufacturing process. Subject of analysis is a company which produce vacuum pumps and machine parts from aluminium castings and billets. My records and final analysis are a recommendation of the suitable coolant for the manufacturing process in terms of their Lean production system´s KPI´s (Safety, Quality, Delivery and Costs).
