Design of universal belt grinder
Skala, Ondřej ; Kvarda, Daniel (referee) ; Valena, Martin (advisor)
This thesis focuses on the design of a universal belt grinder with the capability for both vertical and horizontal grinding, aiming to maximize its usage potential. Several grinding attachments have been designed for the grinder, with attention to high quality, versatility, and user-friendly operation. The theoretical part describes grinding, types of belt grinders, and abrasive belts. Based on the research, specific requirements for the belt grinder are established, and a suitable type of construction is selected from the conceptual solutions. This is followed by a design proposal supported by calculations necessary for the proper and reliable operation of the machine and stress analysis using the finite element method. The final part describes the manufacturing and assembly of the machine, concluding with the verification of the functionality of the entire belt grinder, including all grinding attachments. The result is a fully functional belt grinder that meets the specified requirements.

Design of belt grinder
Denk, Daniel ; Tůma, Jiří (referee) ; Pavlík, Jan (advisor)
Aim of this bachelor thesis is to produce a construction proposal of a belt grinder, which is, with respect to universality, adjustable in different axes. Grinding technology, belt grinder principle and description of the functionally important parts are presented in the first part. Second part is dedicated to the market research of existing belt grinders, evaluation of their construction design of an optimal belt grinder. Third part includes the necessary calculations, construction design analysis and economic evaluation of the optimal grinder and the project also contains its proposed 3D model created with Autodek Inventor Professional 2020 model nad drawing documentation.

Design of belt grinder
Man, Lukáš ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
This Master’s thesis concerns the construction of Belt Grinder. The research part deals with types of designs used in Belt Grinders, grinding technology and analysis of grinding/sanding belts which are used for grinding. With use of qualitative methods as Fault Tree Analysis and Quality Function Deployment, the whole topic is taken apart in more detail, so the topic of Belt Grinder is easier to understand. In the next part of the work, the necessary parameters are calculated and then the construction of a Belt grinder for flat surfaces and rounded grinding are modeled. This is followed by a risk assessment analysis, including forms for estimating and subsequently proposing measures to reduce these risks. Part of the work is also the technical and economic evaluation and estimated costs for the implementation of proposed structure.

Technologie broušení dřeva, stroje a nástroje
Slezáková, Světlana
The grinding process is important for treatment of the wood surface. There are many different machines for a sanding wood, whether manual or mechanical. By the correct grinding of a wooden surface it is achieved better final result. The thesis describes factors that influence the course of grinding. The main factors are the kind of wood, the moisture, the selected grinding tool and the technical condition of the machine. The main objective of the study is to determine and compare the change of surface roughness when changing the grit of the sanding belt and the grinding angle. There were chosen three angles at which the samples were grinded. The study also investigates relation between the coarse grit of the sanding belt and roughening of the surface. The research was conducted on the tree species beech (Fagus sylvatica). A second objective of the study is to prepare the background for the laboratory exercise and the lecture on the topic of grinding materials.

Sanding process and sanding abrasives for wood
Kříženecký, Ondřej ; Sarvašová Kvietková, Monika (advisor) ; Gašparík, Miroslav (referee)
This bachelor thesis deals with the process of sanding and abrasive materials for wood. It characterizes the process equalize inequality surface of the wood and wood-based materials, which is important operations in the finishing products with highest quality level. It describes the basic methods of machining and sanding their effect on the final surface quality. In the introductory section concisely describes the history of sanding. The next part deals with the main factors affecting the sanding process and their influences on sanding wood. The main part is dedicated to the distribution of abrasive instrument. The structure of abrasive and its characteristics. Describes kinds of abrasive materials and their features. It analyzes the production of abrasive. The next sections deals with the determination of surface quality, surface preparation before sanding, repairing defects and storage of abrasive intruments. The last part analyze the machinery for wood sanding and their distribution. Describes a circular, cylindrical and belt sanders and their characteristics.
