[0029] 1 is a front perspective view of a precision roll lathe according to a first embodiment of the present invention, and FIG. 2 is a rear perspective view of the precision roll lathe without a roll installed.

[0030] In Fig. 1 and Fig. 2, numeral 10 denotes a bed. A headstock 12 , a tailstock 14 and a support 16 are installed on the bed 10 . A roll W as a workpiece is rotatably supported by the headstock 12 and the tailstock 14 .

[0031] The head box 12 is located at one end of the bed 10 in the longitudinal direction. The headstock 12 includes a box body 17 , a main shaft 18 , a chuck 19 fixed on the front end of the main shaft 18 and a servo motor 20 for driving the main shaft 18 . The main shaft 18 is supported by a hydrostatic oil bearing (not shown) provided in the case 17 . The chuck 19 holds the spindle of the roll W, and transmits the rotation of the spindle 18 to the roll W. As shown in FIG.

[0067] Now, a precision roll lathe according to a second embodiment of the present invention will be described with reference to FIG. 7 .

[0068] The roll lathe of this embodiment is characterized in that a chip suction device 60 shown in FIG. 7 is provided. As shown in FIG. 7 , the chip suction device 60 includes a moving table 61 and a support arm 62 . The moving table 61 moves on the bed 10 in a direction parallel to the moving direction of the slider 41 . A ball screw is used as a driving mechanism of the moving table 61, and a W-axis is used as a control axis of the driving mechanism.

[0069] The support arm 62 is fixed on the moving table 61 , and the support arm 62 extends toward the roller W. As shown in FIG. The suction duct 63 is supported by a support arm 62 . A joint 64 is mounted on the downwardly bent end of the suction duct 63 , and a suction nozzle 65 is connected to the suction duct 63 via the joint 64 . The tip of the suction nozzle 65 is located near t...

Abstract

There is provided a precision roll turning lathe which can perform machining of fine grooves at a dramatically higher speed as compared to conventional roll turning lathes, thus significantly shortening time taken for machining one groove. The precision roll turning lathe includes: a bed; a headstock, mounted on the bed, having a main spindle for rotating a roll as a workpiece while holding one end of the roll by means of a chuck; a tail stock, mounted on the bed and disposed opposite the headstock, for rotatably supporting the other end of the roll; a carriage including a saddle mounted on the bed movably in the longitudinal direction of the roll, and a table mounted on the saddle movably in a direction perpendicular to the longitudinal direction of the roll; and an air slide apparatus, mounted on the table, including a guide rail extending parallel to the roll in the longitudinal direction, an air slider having a diamond tool, capable of traveling in a floating state on the guide rail, and a linear motor for driving the air slider.

Description

technical field [0001] The present invention relates to a precision roll lathe, and more particularly to a precision roll lathe used in the processing of rolling dies for extrusion molding of optical products such as lens sheets. Background technique [0002] A roll lathe is a machine tool used to process rolls. A roll lathe is a lathe in which a tool holder attached such as a diamond tool is mounted on a stand, and the roll is rotated by a head box and the stand is fed in the lateral direction (X-axis direction) of the roll, thereby basically using A ring groove is machined on the roller. When machining the axial groove on the roller, when the roller is indexed by the headstock (C-axis), the bracket is fed along the longitudinal direction of the roller (Z-axis direction), thereby machining the axial groove. [0003] With the advancement of mechanical control technology in recent years, ultra-precision machining using roll lathes has been realized. At present, roll lathes...
