Document Type and Number:
Japanese Patent JP3218481
Kind Code:
B2
Abstract:
PURPOSE: To provide a lathe capable of using as a Y-axis-function-cum lathe in usual, of sharply improving rigidity when a Y-axis-function is unnecessary, and of supporting right and left turrets in the same high rigidity, in the specifica tion without the Y-axis function in a facing type two-axis lathe.
CONSTITUTION: A Y-axis-function-cum lathe is applied to the lathe, etc., of facing two-wxis 2 turrets, in which one-side and the other side main spindles 2 and 3 are made position-fixed and movable together with a head stock 10 respectively. In the movable side main spindle 3, tool-feeding is made by moving the head stock 10. A turret 5, juxtaposed on the movable side main spindle 3, is supported movably in two axis directions of X and Y, and a Y-axis function is given to make working possible at the eccentric position of work. In this case, an X-axis feed bar 16 is provided on a bed 1, and a Y-axis feed bar 17 is provided on it. A turret 5 is provided on the Y-axis feed bar 17. In the case of a specification without a Y-axis function, the X-axis feed bar 16 is removed to provide the Y-axis feed bar 16 on an X-axis guide 18.
