Motori elettrici – Electric motors ME-1

Determinare con esattezza lo spessore massimo che e possibile tagliare e un fattore importante nel processo di lavorazione della pietra. La tabella sottostante mette a disposizione una serie di valori utili per una prima stima sulla possibility di taglio e sulle velocita di rotazione ideali per la lavorazione. La velocita di rotazione del disco dipende dal tipo di materiale, per i piu rappresentativi vengono forniti i valori minimi e massimi ricavati dai cataloghi dei piu importanti costruttori mondiali di dischi abrasivi. Accurately determine the maximum thickness that can be cut is an important factor in the process of working stone. The table below provides a number of useful values for a first estimation on the possibility of cutting and rotation speed ideal for processing. The rotation speed of the disk depends on the type of materials, the most representative are provided the minimum and maximum values obtained from the catalogs of the most important manufacturers of abrasive discs. Dimensioni raccomandate Recommended dimensions * La velocita massima indicata si puo raggiungere alimentando il motore tramite inverter. I parametri di configurazione dipendono dal tipo di motore. * Maximum speed can be achieved feeding motor through frequency converter. Parameters must be set up accordingly to the motors. La profondita di taglio (Pt) puo essere velocemente calcolata applicando questa Cutting depth (Pt) can be easily estimated applying this simple rule: semplice regola: Dove: • Pt e la profondita di taglio utile • 0d e il diametro del disco • 0f e il diametro delle flange A e lo spazio di sicurezza affinche le flange non entrino in contatto con il materiale da lavorare, possiamo ritenere adeguato lo spazio di circa 5 mm. Where: • Pt is the available cutting depth • 0d is the diameter of the blade • 0f is the diameter of the flanges A is the area of security so that the flanges do not come into contact with the material to be processed, we can assume adequate space of about 5mm.
