Podle mě je odlehčování jeklů úplná blbost. Když to takhle odlehčí z jedné strany tak se mu to prohne do luku či úplně zkroutí. Nehledě na to, že se tady nejspíš pokouší o nízkonákladvou frézku, když používá rolničkové vedení. Tak takové prořezání také něco stojí. Ten kluk se pokouší o open source konstrukci, vyrendrovaný to má parádně, je vidět, že za tím má hodně práce. A konstruktivní kritice se nebrání. Prosím o Vaše poznámky a komentáře na jeho stránce, moje zásoba angličtiny na to nestačí.Thank you for your comment https://grabcad.com/jan.vanik" onclick="window.open(this.href);return false;. This cnc model is designed to be produced by laser cutting (90% of the mechanical structure). The rectangular steel tubes of the mobile gantry and the fixed frame were chosen for ease of production by laser-tube machine cutting. The cutting of plates on the walls of the profiles is not useless, and brings several advantages: 1) it allows to reduce from 30% to 40% the mass of the tubes which are here in steel sheet of 4mm and 6mm thick, 2) it does not affect the rigidity of the profile with respect to the mechanical stresses undergone during the operation of the cnc, 3) and also, the calculation of the structures was done by taking into account profiles in C ... the use tube is a plus ... 4) Moreover, this lightening of the tubes allows easy access to the assembly screws and nuts of the elements. but also 5) this relief on the mobile gantry allows acceleration and braking and faster travel speed. Other versions of this series of professional cnc, more optimized, and composed mainly of plates are in the process of industrial production. the plans of a complete model will be published with the first videos good day and thanks again for the comments
