Title
(EN) IMPROVED HOTWIRE CUTTING MACHINE
(FR) MACHINE DE DÉCOUPE PAR FIL CHAUD AMÉLIORÉE
Abstract
(EN)
An improved hot wire cutting machine, comprising: a heated wire, at least one spring and at least one grooved rod supported on a plurality of end bearings and a plurality of optional bearings at middle of the rod. A splined shaft pair on which multiple discs can slide holding the wire, with motor capable of providing a to-fro oscillating sawing motion action on the wire wherein the grooved rod is free to rotate with help of bearing or synchronized motor. The cutting wire can be a composition of plurality of wires.
(FR)
L'invention concerne une machine de découpe par fil chaud améliorée, comprenant : un fil chauffé, au moins un ressort et au moins une tige rainurée supportée sur une pluralité de paliers d'extrémité et une pluralité de paliers facultatifs au milieu de la tige. Une paire d'arbres cannelés sur laquelle de multiples disques peuvent coulisser en maintenant le fil, avec un moteur capable de fournir une action de mouvement de sciage oscillant en va-et-vient sur le fil, la tige rainurée étant libre de tourner avec l'aide d'un moteur synchronisé ou palier. Le fil de coupe peut être une composition de plusieurs fils.
