(EN) THREAD GRINDING MACHINE
(FR) MACHINE A RECTIFIER LES FILETAGES
(JA) ねじ研削盤
Abstract
(EN)
A thread grinding machine for grinding a thread shaft (3), wherein the thread shaft (3) to be ground is set on a work fixing stand (4) having a work positioning groove (40) of V-shape in cross section on a work table (2), and a grinding wheel (6) is moved to cut the thread shaft (3) set in the work positioning groove (40) from a vertical upper side, whereby the straightness of the thread shaft (3) can be maintained against a grinding resistance and the thread shaft (3) can be accurately ground.
(FR)
L'invention concerne une machine à rectifier destinée à rectifier une tige filetée (3). On installe la tige filetée (3) à meuler sur un support de fixation (4) présentant une rainure de positionnement (40) ayant une section transversale en V sur une table de travail (2). On déplace une meule (6) pour usiner la tige filetée (3) installée dans la rainure de positionnement (40) à partir d'un côté supérieur vertical. La rectitude de la tige filetée (3) peut être maintenue contre une résistance de meulage et la tige filetée (3) peut être meulée avec précision.
