High-Speed Steel Drills and their Uses
Jaroš, Aleš ; Dvořák, Jaromír (referee) ; Sliwková, Petra (advisor)
This Bachelor thesis, as one can deduct from the title, deals with high-speed steel drills and their uses into practice. The problem of high-speed steel is described step by step from division, chemist to heat treatment. Fundamental features of drilling method and tools that are suitable for drilling are described either. The last part of Bachelor thesis is focused on producers and application of high-speed steel drills to practice.

Powertrain of in-line four-cylinder spark ignition engine
Mačuga, Martin ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
According to given to cylinder diameter, stroke and ideal indicator diagram we will investigate with maximum cylinder pressure and further design for proportions piston insider ( piston and piston - pin) as well as piston rod. Then shall do strength calculation upper connecting-rod eye according to given to calculations namely for the select material of piston rod. In the end we evaluate the select material whether is for suggested piston rod fit.

Výroba a vlastnosti vrtáků
Kukla, Jan
The bachelor work is based on a survey of the production and basic characteristic of the production and properties of drills in the company, which deals with the total production of drilling tools. Five-axis CNC tool grinders are able to achieve high precision processing with a wide range of different types of materials. Hardness, toughness and heat resistance of drill bits are specified prefabricated bore material (aluminium, stainless steel, etc.), the geometry of a cutting edge drills (Mitsubishi, Gühring, "RDS", etc.) and the type of the coating (TiAlN, AlCrN, ArTiN, CC Alu speed, etc.), or processing of the surface (nitriding, blackening).
