Abstract
U radu su prikazani postupci valjanja i brušenja površina te usporedba utjecaja istih na kvalitetu obrađene površine. Postupak valjanja temelji se na zaglađivanju površine utiskivanjem vrhova obrađivane površine u sam materijal čime se dobiju hrapavosti Ra 0,2 do Ra 0,4 i otvrdnuće obrađivane površine od 20 HB do 40 HB veće od početne tvrdoće. Postupak brušenja spada u skupinu obrada materijala odvajanjem čestica te veliki broj reznih oštrica skida određeni sloj materijala ostavljajući površinu materijala s malim stupnjem površinske hrapavosti, minimalnog iznosa Ra 0,4. Za provedbu eksperimentalnog dijela uzet je materijal 42CrMo4 te se mjerenjem hrapavosti obrađivanih površina došlo do zaključka da je postupkom valjanja lakše ostvariti manju hrapavost površine za navedeni materijal.
Abstract (english)
The paper presents procedures for rolling and grinding and compare the impact on the quality of the machined surface Roller burnishing process is based on smoothing by impressing peaks of processed part in the material to form the roughness Ra 0.2 to Ra 0.4 and hardening of the working surface of 20 HB to 40 HB greater than the initial hardness. Grinding is one of a group of processing material removal processes and a large number of cutting edges off a certain layer of the material leaving the surface of the material with a small degree of surface roughness, the minimum amount of Ra 0.4. For the implementation of the experimental part was taken 42CrMo4 material and measuring the roughness of the processed surface the conclusion was that the process of roller burnishing was easier to achieve a lower surface roughness of this material.
