Pokia\u013e ide o jadrov\u00e9 v\u0155ta\u010dky, karbidov\u00e9 jadrov\u00e9 v\u0155ta\u010dky s\u00fa zvy\u010dajne najlacnej\u0161ou mo\u017enos\u0165ou.<\/span><\/p>\n

Na rozdiel od karbidov\u00fdch vrt\u00e1kov maj\u00fa zuby diamantov\u00fdch jadrov\u00fdch vrt\u00e1kov v sebe zabudovan\u00e9 diamanty. Preto\u017ee diamanty s\u00fa ve\u013emi tvrd\u00e9, prebr\u00fasia si cestu cez ostr\u00fd, \u010disto rezan\u00fd povrch, ktor\u00fd sa sna\u017e\u00edte vytvori\u0165.<\/span><\/p>\n

V skuto\u010dnosti existuj\u00fa dva r\u00f4zne typy diamantov\u00fdch dut\u00fdch vrt\u00e1kov \u2013 na mokr\u00e9 rezanie a na such\u00e9 rezanie. V podstate sa diamantov\u00e9 jadrov\u00e9 vrt\u00e1ky na mokr\u00e9 rezanie po\u010das v\u0155tania chladia vodou, zatia\u013e \u010do diamantov\u00e9 jadrov\u00e9 vrt\u00e1ky na such\u00e9 rezanie sa jednoducho pou\u017e\u00edvaj\u00fa nasucho.<\/span><\/p>\n

Ke\u010f\u017ee pri v\u0155tan\u00ed vznik\u00e1 ve\u013ea tepla, je potrebn\u00e9 udr\u017eiava\u0165 diamantov\u00fa jadrov\u00fa vrtn\u00fa korunku \u010do najchladnej\u0161iu, aby sa minimalizovalo zbyto\u010dn\u00e9 po\u0161kodenie rezac\u00edch zubov. Ak je povrch rezac\u00edch zubov vystaven\u00fd pr\u00edli\u0161 ve\u013ek\u00e9mu teplu, kov, ktor\u00fd ich obklopuje, sa roztav\u00ed a zakryje diamant, \u010d\u00edm sa zn\u00ed\u017ei \u00fa\u010dinnos\u0165 rezania. Ak k tomu d\u00f4jde, korunka bude musie\u0165 by\u0165 \u201eopraven\u00e1\u201c, aby sa diamant op\u00e4\u0165 odhalil.<\/span><\/p>\n

Zhrnutie: Na pr\u00e1cu v interi\u00e9ri sa be\u017ene pou\u017e\u00edvaj\u00fa diamantov\u00e9 vrt\u00e1ky na such\u00e9 rezanie a na pr\u00e1cu v exteri\u00e9ri sa pou\u017e\u00edvaj\u00fa diamantov\u00e9 vrt\u00e1ky na mokr\u00e9 rezanie.<\/span><\/p>\n

Pri pou\u017e\u00edvan\u00ed such\u00fdch rezac\u00edch bitov ich treba udr\u017eiava\u0165 \u010do najchladnej\u0161ie. Na tento \u00fa\u010del by sa mali pou\u017e\u00edva\u0165 kr\u00e1tkodobo a cel\u00fd bit by sa mal pravidelne vybera\u0165 z otvoru a vystavova\u0165 vzduchu, aby sa rozpt\u00fdlilo teplo. Napriek tomu sa diamantov\u00e9 jadrov\u00e9 bity na such\u00e9 rezanie nemusia pou\u017e\u00edva\u0165 nasucho, m\u00f4\u017eete ich pou\u017ei\u0165 aj namokro.<\/span><\/p>\n
