This diploma thesis deals with the design, production and analysis of a special clamping device for milling process of products. The current small-serial production of screen LCD brackets of aluminum alloy was carried out on the CNC machining center using an outdated clamping method, which negatively influenced the position stability of the workpiece and, consequently, the product. The processing cycles were relatively long due to the time-consuming method of clamping the workpiece and the time-consuming cutting process. The designed clamping device enables, due to an innovative clamping approach, quick and easy clamping, and better positioning stability of clamped workpieces. Additional optimization of processing technology helps to speed up machining process. Combined, this results in a shortening of the processed cycle. It is also possible to achieve a better quality of the surface of the product, which is very important for the product with aesthetic requirements, such as that of the LCD screen brackets. The suitability of the newly designed clamping device was also confirmed by cost analysis.
