Pokud nakupujete stroje, vyb\u00edr\u00e1te dodavatele nebo nab\u00edz\u00edte programy pro tenk\u00e9 kovov\u00e9 sk\u0159\u00edn\u011b, p\u0159esta\u0148te se pt\u00e1t pouze na zna\u010dku laseru nebo v\u00fdkon laseru, kter\u00fd tov\u00e1rna vlastn\u00ed. Ptejte se, jak se vypo\u0159\u00e1d\u00e1vaj\u00ed se zkreslen\u00edm. Ptejte se, jak programuj\u00ed distribuci tepla. Ptejte se, jak si porad\u00ed s nerezovou ocel\u00ed 304 a hlin\u00edkem.
