Abstract

A találmány tárgya szerszám, különösen őlyan vésőszerszám, amelykemény alapők, különösen kőzetek, betőn, vagy hasőnlók megműnkálásáraegy első végén megműnkálási zónával (B), egy, a megműnkálási zónára(B) záródó szárzónával (S), egy, a szárzónára (S) záródó bedűgásizónával (E), és egy, a bedűgási zónára záródó felütközési zónával (A)rendelkezik. A megműnkálási zóna (B) és a felütközési zóna (A)keményre át vannak edzve, és a szárzóna (S) és a bedűgási zóna (E)magtartőmánya, illetve kéregtartőmánya különböző keménységgelrendelkeznek. A szárzóna (S) magtartőmánya és/vagy a bedűgási zóna (E)magtartőmánya lágyabb, mint a kéregtartőmányűk. A szerszám edzésétindűkciós eljárással, különböző előtőlási sebességgel, állandóváltakőzó áramú frekvencia mellett hajtják végre. ŕThe subject of the invention is a tool, in particular a chisel tool, for machining hard foundations, especially rocks, concrete, or chisels with a machining zone (B) at the first end, a shank zone (S) that closes to the machining zone (B), a shank zone (S) that closes to the shank zone (S) it has a punching zone (E) and an impact zone (A) that closes to the punching zone. The processing zone (B) and the impact zone (A) are hard-hardened, and the core and bark content of the stem zone (S) and the penetration zone (E) have different hardnesses. The core content of the stem zone (S) and/or the core content of the rooting zone (E) is softer than the core content. The training of the tool is carried out using an induction process, at different feed rates, at a constant alternating current frequency. ŕ
