Barrel Rifling Machine Designe and Function Analysis
Loutocký, Petr ; Hammer, Miloš (referee) ; Jankových, Róbert (advisor)
This master’s thesis is devoted to rifling technologies of the barrel bore of fire and gas arms. In cooperation with the company Winston Production, s.r.o. also enters into operation issues of selected manufacturing machine Zs 151 for barrel rifling. It contains an analysis of legislative demands on the technical documentation, description of the construction and function of machinery and materials for the creation of local operating safety rules for its operation. The part of work is also 3D model of the machine created in software SolidWorks.

Efficiency Improvement Proposal of Production of Semi-Finished Products for Gun-Barrels
Zemánek, Patrik ; Botek, Jan (referee) ; Sedlák, Josef (advisor)
This thesis is focused for manufacturing of a gun barrels and his issues. In thesis is involved introducing of the company Česká zbrojovka a.s. and definition of hand fired guns. Written analysis present the state of a technological process and describe an individual phase of manufacturing of the semi-finished product of gun barrel and the following conclusion of a complex manufacturing of a gun barrel from the semi-finished product to the stand, when the gun barrel installed into the gun is. Subsequently are suggested possibly solutions of manufacturing rationalization and possibly purchasing of a new modern CNC machines. In the end is accomplished a technical-economic evaluation, which compares existing and suggesting of the technology.

Materials for Production of Small Firearms
Neužil, Tomáš ; Lidmila, Zdeněk (referee) ; Molliková, Eva (advisor)
The aim of this thesis is to summarize information of small firearms, both in terms of their historical development and the origins of the crafting firearms, through the development of locks and a history of the weapons, which were during this development invented, to the emergence of a single bullet, which is still used today, so from the perspective of our time focusing on the choice of barrel materials, the issue of loading and fatigue barrel and bore when fired and conventional production technologies barrel bore.

Making a replica of cannon barell
Helešic, Jan ; Ostratický, Marek (referee) ; Bořil, Petr (advisor)
The topic of the bachelor's thesis is the production of a cannon replica mainly on the basis of a suitably chosen technology. On the basis of a literary study, which consisted mainly of an examination of historical sources, gravitational casting was chosen. The mold was formed from the inorganic molding compound GEOPOL. The model of the barrel was created according to the historical model of the ship's cannon. The model was created by CNC machining and the material is artificial wood. Cast iron with flake graphite, which has suitable foundry properties, was chosen as the casting material. The conclusion of the thesis contains an evaluation of the selected technology.

Firearms in the Middle East. Beginnings, Production and Use.
Beran, Pavel ; Bouzek, Jan (advisor)
This thesis deals with the development of the hand-held firearms in the Middle East with an emphasis on the period from the 15th to the end of the 18th century. In some passages it also marginally mentions the early 19th century. The first part of the thesis concentrates on the development of firearms in a historical context. The focus is primarily on the Ottoman Empire and partially on Egypt. Among other topics it also analyses the practical use of firearms and the related military tactics including the presence of firearms in major battles, as shown on contemporary paintings and miniatures. In the second part the author deals with the technical development of hand-held firearms. This section focuses mostly on the components of firearms and their development. This section also in some degree deals with the artistic aspects of the preserved firearms. The supplements consist of numerous photographs of the preserved exhibits in Czech and foreign collections and also of other visual materials. Keywords firearms, gunpowder, Middle East, Ottoman Empire, Mamluks, Egypt, flintlock, matchlock, miquelet, stock, barrel, decoration, miniatures
