V\u00fdroba hriade\u013eov m\u00e1 dlh\u00e9 historick\u00e9 pozadie. Najstar\u0161ie d\u00f4kazy poch\u00e1dzaj\u00fa z ir\u00e1nskeho mesta Persepolis, kde stroje tvarovali kovov\u00e9 ty\u010de do hriade\u013eov. Tento proces sa vyv\u00edjal po st\u00e1ro\u010dia. Vyhovuje potreb\u00e1m priemyseln\u00fdch odvetv\u00ed, ako je automobilov\u00fd, leteck\u00fd a stroj\u00e1rsky priemysel.

Z\u00e1kazkov\u00e1 v\u00fdroba hriade\u013eov m\u00e1 tri hlavn\u00e9 v\u00fdhody. Maj\u00fa presn\u00e9 rozmery, presnos\u0165 a vynikaj\u00facu povrchov\u00fa \u00fapravu. Proces sa za\u010d\u00edna stanoven\u00edm \u00fa\u010delu pou\u017eitia hriade\u013ea. To zah\u0155\u0148a podmienky, ktor\u00fdm bude podlieha\u0165, a po\u017eiadavky projektu. T\u00fdm sa zabezpe\u010d\u00ed, \u017ee ka\u017ed\u00fd z nich bude presn\u00fd a bude fungova\u0165 tak, ako je potrebn\u00e9.<\/p>\n\n

V\u00fdber materi\u00e1lu<\/h3>\n\n

Rozhoduj\u00faci je v\u00fdber materi\u00e1lu. Hlin\u00edk, uhl\u00edkov\u00e9 vl\u00e1kna, oce\u013e a plast s\u00fa materi\u00e1ly pou\u017e\u00edvan\u00e9 na in\u00e9 \u00fa\u010dely. Napr\u00edklad v priemysle sa pou\u017e\u00edva oce\u013e, preto\u017ee je n\u00e1ro\u010dn\u00e1. Hlin\u00edk sa pou\u017e\u00edva v rekrea\u010dn\u00fdch vozidl\u00e1ch najm\u00e4 pre svoju \u013eahkos\u0165.<\/p>\n\n

Dizajn a programovanie<\/h3>\n\n

Vo f\u00e1ze n\u00e1vrhu by sa mal stanovi\u0165 materi\u00e1l pou\u017eit\u00fd na v\u00fdrobu hriade\u013ea, jeho priemer a d\u013a\u017eka. Potom sa v softv\u00e9ri CAD vytvor\u00ed podrobn\u00fd pl\u00e1n. Po tomto procese obr\u00e1bania sa naprogramuje softv\u00e9r CAM na vytvorenie dr\u00e1h n\u00e1strojov a CNC programu (G-k\u00f3d).<\/p>\n\n

Rezanie a tvarovanie<\/h3>\n\n

Tento materi\u00e1l sa narez\u00e1va do tvaru pomocou p\u00edl alebo laserov a potom sa opracuje na potrebn\u00fa ve\u013ekos\u0165 pomocou fr\u00e9z CNC. Hrubovanie zah\u0155\u0148a rezanie materi\u00e1lu na men\u0161ie kusy a ich s\u00fastru\u017eenie pomocou fr\u00e9zy na presn\u00e9 tvarovanie.<\/p>\n\n

Nastavenie stroja<\/h3>\n\n

Ak chcete nastavi\u0165 stroj CNC, mus\u00edte si okrem in\u00e9ho vybra\u0165 vhodn\u00fd typ stroja – fr\u00e9zku alebo s\u00fastruh, pripravi\u0165 obrobok a vybra\u0165 rezn\u00e9 n\u00e1stroje. S\u00favis\u00ed to s upevnen\u00edm dielov pomocou up\u00ednac\u00edch pr\u00edpravkov a pou\u017eit\u00edm ostr\u00fdch rezn\u00fdch n\u00e1strojov, aby sa dosiahla presnos\u0165.<\/p>\n\n

Proces obr\u00e1bania hriade\u013ea<\/h3>\n\n

CNC s\u00fastru\u017eenie dobre zvl\u00e1da valcov\u00e9 diely. Je ide\u00e1lny na v\u00fdrobu hriade\u013eov na mieru. Mus\u00ed tie\u017e zah\u0155\u0148a\u0165 starostliv\u00e9 monitorovanie a kontroly po\u010das cel\u00e9ho procesu. Ich cie\u013eom je zisti\u0165 kvalitu.<\/p>\n\n

Tepeln\u00e9 spracovanie<\/h3>\n\n

Existuj\u00fa r\u00f4zne typy procesov tepeln\u00e9ho spracovania. Kladivov\u00e9 opracovanie zabezpe\u010duje, \u017ee hriade\u013e znesie zmeny teploty a prostredia po\u010das pou\u017e\u00edvania.<\/p>\n\n

Povrchov\u00e1 \u00faprava<\/h3>\n\n

Povrch hriade\u013eov mo\u017eno vylep\u0161i\u0165 tryskan\u00edm, eloxovan\u00edm alebo pasiv\u00e1ciou. Ak sa to dosiahne, bud\u00fa lep\u0161ie sl\u00fa\u017ei\u0165 svojmu \u00fa\u010delu a z\u00e1rove\u0148 bud\u00fa v\u017edy dobre vyzera\u0165. To sa vykon\u00e1va aj galvanick\u00fdm pokovovan\u00edm. Tieto met\u00f3dy sp\u013a\u0148aj\u00fa \u0161pecifik\u00e1cie po\u017eadovan\u00e9 pre r\u00f4zne aplik\u00e1cie.<\/p>\n\n

In\u0161pekcia a kontrola kvality<\/h3>\n\n

Na meranie v\u0161etk\u00fdch vlastn\u00fdch hriade\u013eov sa pou\u017e\u00edvaj\u00fa mikrometre, meradl\u00e1, strmene at\u010f., aby sa zabezpe\u010dilo, \u017ee sp\u013a\u0148aj\u00fa po\u017eadovan\u00e9 tolerancie.<\/p>\n\n

Balenie<\/h3>\n\n

Nakoniec sa hriadele starostlivo zabalia. Cie\u013eom je zabr\u00e1ni\u0165 po\u0161kodeniu pri preprave. Musia sa dosta\u0165 na miesto ur\u010denia v neporu\u0161enom stave, aby sa mohli pou\u017e\u00edva\u0165 v r\u00f4znych aplik\u00e1ci\u00e1ch.<\/p>\n\n
