Konstrukce malého svislého soustruhu / Design of small vertical turning machine

Rybář, Pavel January 2011 (has links)
Task of this project is design of small vertical lathe. First part is focused on theory of turning technology, sort of lathe types, overview of vertical lathes including description of componets which vertical lathes consist of. At the second part of this project there is performed a propose of the machined part and a propose of cutting machine. The last part of this project provides base structure calculations and analysis needed for design proposal of a small vertical lathe according to specified parametres.

Využití netradičních materiálů ve stavbě svislých soustruhů / Utilisation of innovative materials at design of vertical lathes

Augustin, Petr January 2011 (has links)
In my thesis, I have chosen to concentrate on the replacement of traditional materials by more unconventional ones. My aim is thus to pay attention to theoretical and practical implications that such replacement would induce and to evaluate the pros and cons of such practice. I am going to fucus on the Hulin-located company TOSHULIN which produces vertical lathes.

Polymerbetonový rám svislého soustruhu / Polymerconcret Frame of Vertical Lathe

Buksa, Jan January 2008 (has links)
This work describes construction and calculation of vertical lathe bed designed by request of company TOSHULIN. Apart from a sum of theoretical knowledge, the information contained in it should also serve in practice as a comprehensive guidance for construction vertical lathe bed from this material. The approach is specific by reason of that is necessary to observe functional proportions at contemporary producing part, which is usied for construction vertical lathes. There is a design of construction in this work, which gives better results mechanic, dynamic and thermal features of this part in some way.
