Abstract

Inventia se refera la un procedeu si o masina de superfinisat suprafete metalice cilindrice si conice, cu utilizare în industria de prelucrare a fibrelor, firelor si foliilor. Procedeul consta în prelucrarea unei suprafete rectificata în prealabil, care are o rugozitate Ra=0,8÷0,2 miu, dupa care se face o finisare în trei trepte, utilizîndu-se pentru piesa de prelucrat o viteza de rotatie cuprinsa între 8 si 12 rot/min, iar pentru discul de cauciuc o viteza perfecta cuprinsa între 11 si 12 m/s, avînd un avans longitudinal al discului de 0,5÷1,5 mm/rot, pe disc fiind prevazuta o coala abraziva ce are o granulatie cuprinsa între 220 si 800, iar masina pentru realizarea procedeului este constituita dintr-un batiu, prevazut cu doua papusi, una fixa si una mobila, si cu un dispozitiv de superfinisare.The invention relates to a process and a superfinishing machine for cylindrical and conical metal surfaces, for use in the fiber, yarn and foil processing industry. The process consists of machining a pre-ground surface, which has a roughness Ra = 0.8 ÷ 0.2 miu, after which a three-stage finishing is made, using for the workpiece a speed of rotation between 8 and 12 rpm, and for the rubber disc a perfect speed of 11 to 12 m / s, having a longitudinal feed of the disc of 0.5 ÷ 1.5 mm / rot, the disc being provided with an abrasive wheel having a grain size ranging from 220 to 800, and the machine for carrying out the process consists of a bead, provided with two dolls, one fixed and one mobile, and a superfinishing device.
