Abstract
(EN)
Provided is a lathe whereby a product having enhanced dimensional accuracy can be obtained. This lathe 1 comprises a first headstock (11), a second headstock (21), a servo device (MZ2) for causing the second headstock (21) to move in the center axis direction of a second main shaft (22), and a control part U1 for controlling the opening/closing action of gripping parts 13, 23 and the movement of the second headstock (21) caused via the servo device (MZ2). The control part U1 opens a second gripping part 23 and causes the second headstock (21) to move toward the first headstock (11) in a state in which the servo device (MZ2) is limited to a torque lower than the maximum torque, imparts a predetermined torque fluctuation to the servo device (MZ2) and detects a change (∆Zi) in the position of the second headstock (21) in the center axis direction of the second main shaft, and determines whether a foreign body 800 is present between the second gripping part 23 and a work piece W0 on the basis of the change (∆Zi) in position detected in the range in which the second gripping part 23 grips the work piece W0.

L'invention concerne un tour permettant d'obtenir un produit présentant une précision dimensionnelle améliorée. Ledit tour (1) comprend une première poupée fixe (11), une seconde poupée fixe (21), un dispositif d'asservissement (MZ2) destiné à amener la seconde poupée fixe (21) à se déplacer dans la direction d'axe central d'un second arbre principal (22), et une partie de commande U1 destinée à commander l'action d'ouverture/de fermeture de parties de préhension (13, 23) et le mouvement de la seconde poupée fixe (21) provoqué par le dispositif d'asservissement (MZ2). La partie de commande U1 ouvre une seconde partie de préhension (23) et amène la seconde poupée fixe (21) à se déplacer vers la première poupée fixe (11) dans un état dans lequel le dispositif d'asservissement (MZ2) est limité à un couple inférieur au couple maximal, communique une fluctuation de couple prédéfinie au dispositif d'asservissement (MZ2) et détecte un changement (∆Zi) de la position de la seconde poupée fixe (21) dans la direction d'axe central du second arbre principal, et détermine si un corps étranger (800) est présent entre la seconde partie de préhension (23) et une pièce W0 sur la base du changement (∆Zi) de la position détectée dans la plage dans laquelle la seconde partie de préhension (23) saisit la pièce W0.

製品の寸法精度を向上させることが可能な旋盤を提供する。旋盤1は、第一主軸台(11)、第二主軸台(21)、該第二主軸台(21)を第二主軸(22)の中心線方向へ移動させるサーボ装置(MZ2)、並びに、把持部13,23の開閉動作及びサーボ装置(MZ2)を介した第二主軸台(21)の移動を制御する制御部U1を備える。制御部U1は、第二把持部23を開いてサーボ装置(MZ2)を最大トルクよりも低いトルクに制限した状態で第二主軸台(21)を第一主軸台(11)の方へ移動させ、サーボ装置(MZ2)に所定のトルク変動を与えて第二主軸の中心線方向における第二主軸台(21)の位置の変化(ΔZi)を検出し、第二把持部23がワークW0を把持する範囲において検出した位置の変化(ΔZi)に基づいて第二把持部23とワークW0との間の異物800の有無を判別する。
